Welcome to the Quest Diagnostics fourth quarter and full year 2018 conference call. At the request of the company, this call is being recorded. The entire contents of the call, including the presentation and question and answer session that will follow, are copyrighted property of Quest Diagnostics with all rights reserved. Any redistribution, retransmission, or rebroadcast of this call in any form without the written consent of Quest Diagnostics is strictly prohibited. I would like to introduce Shawn Bevec, Vice President of Investor Relations for Quest Diagnostics. Go ahead, please.
Thank you. Good morning. I'm here with Steve Rusckowski, our Chairman, President, and Chief Executive Officer, and Mark Guinan, our Chief Financial Officer. During this call, we may make forward-looking statements and will discuss non-GAAP measures. We provide a reconciliation of non-GAAP measures to comparable GAAP measures in the tables to our earnings press release. Actual results may differ materially from those projected. Risks and uncertainties that may affect Quest Diagnostics' future results include, but are not limited to, those described in our most recent annual report on Form 10-K and subsequently filed quarterly reports on Form 10-Q and current reports on Form 8-K. For this call, references to reported EPS refer to reported diluted EPS, and references to adjusted EPS refer to adjusted diluted EPS excluding amortization expense.
Growth rates associated with our long-term outlook projections, including total revenue growth, revenue growth from acquisitions, organic revenue growth, and adjusted earnings growth are compound annual growth rates. As a reminder, the company now reports uncollectible balances associated with patient responsibility, which we will refer to as patient concessions as a reduction in net revenues, when historically, these amounts were classified as bad debt expense within SG&A expenses. Now here's Steve Rusckowski.
Thanks, Shawn. Thanks, everyone, for joining us today. This morning, we'll discuss the fourth quarter and full year 2018 and review progress on our two-point strategy. Mark will provide more detail on the results and take you through our 2019 guidance. For the fourth quarter, revenues decreased 1.4%. Reported EPS was $0.92, down about 50% from the same period in 2017. Adjusted EPS was $1.36, down 2.9%. Performance in the quarter reflects increased reimbursement headwinds, as well as softer organic volume than we expected at Investor Day, and the change in estimate of reserves for revenue and accounts receivable, which Mark will cover later in the call. For the full year of 2018, revenues grew 1.7%. Reported EPS declined roughly 4% to $5.29. Adjusted EPS grew approximately 17% to $6.31. In 2018, we grew revenues, adjusted earnings, and cash from operations despite some challenges in the marketplace.
Mark will update you on the quarter and share our perspective on 2019. Quest is well-positioned in 2019 to grow share and deliver revenue growth as our in-network status now extends to approximately 90% of commercially insured lives in the U.S. Volumes are off to a good start this year. Our guidance for 2019 reflects our expectation that strong volume growth will continue throughout the year. It also reflects significant reimbursement pressure, partially offset by our continued execution of our Invigorate program. As we discussed at our Investor Day in November, we are poised for growth based on three fundamental changes in the marketplace. First, PAMA-driven reimbursement pressure is the catalyst for structural change. In 2019, we expect about a 10% reduction in Medicare reimbursement rates and a similar reduction in 2020.
The impact of these cuts will be more significant on smaller, independent hospital outreach laboratories, which we believe could eliminate the majority of their profit and will provide a catalyst for market consolidation. Second, payers are more focused than ever on driving better value in their lab spend, which supports our plan to gain share. Finally, nobody cares more about the variation in healthcare costs than employers and their employees, the country's largest payer. Increasingly, patients are motivated to find the high-value, low-price providers like Quest. We are very well-positioned to benefit from these trends. Our strategy to accelerate growth has five elements. Now we'll share the progress we've made. First, we aim to grow more than 2% this year for M&A. In 2018, acquisitions contributed more than 3% to revenue growth.
The nine deals we announced and closed since the beginning of 2018 position us well to meet our 2019 target. Earlier this week, we completed the acquisition of the clinical laboratory services business of Boyce & Bynum, a leading provider of diagnostic and clinical laboratory services in the Midwest. The second element is to expand relationships with health plans and hospital health systems. First, on health plans. We're entering 2019 with the best access this company's had in over a decade. We've added 43 million lives, which represents about a billion-dollar opportunity for Quest as a result of our in-network status with UnitedHealthcare, Horizon Blue Cross Blue Shield of New Jersey, and Blue Cross and Blue Shield of Georgia. As I said earlier, we have already seen encouraging volume growth early in 2019 resulting from this expanded network access.
Hospital health systems are facing unprecedented financial pressures and are therefore motivated to discuss ways we can help them with their lab strategy. We recently signed two new professional laboratory services agreements in the Southeast region. In both relationships, we will provide full lab management, employing technical lab staff, providing operational lab oversight, and maintaining responsibility for the laboratory supply chain. As we outlined at our Investor Day, most hospital CEOs and CFOs are still not fully aware of PAMA, which impacts hospital outreach labs. We believe that as this impact of PAMA becomes increasingly more visible, hospitals will be more motivated to work with us on their laboratory strategy. The third element of our growth strategy is to offer the broadest access to diagnostic innovation. We made key acquisitions to expand our capability and enhance our service offerings in 2018.
We saw strong double-digit growth in 2018 from a number of key test categories, including Prescription Drug Monitoring, tuberculosis testing, and Cardio IQ. In 2018, we made significant progress executing the fourth element of our growth strategy, which is to be the laboratory provider of choice for consumers. Before arriving at a Patient Service Center, patients can check in electronically through MyQuest and view estimated wait times before making an appointment. At the Patient Service Center or in the physician's office, our enhanced real-time estimator lets patients know their financial responsibility before we collect their specimen. Once the results are available, patients can view them through MyQuest digital platform, which is now available for more than 6.5 million users, or they can review them on the Apple Health app. We continue to build out our industry-leading retail strategy.
By year-end, we'll be in more than 200 Safeway and Walmart locations. In 2018, we launched QuestDirect, a service which enables consumers to order tests without a doctor's script in the continental U.S., and we're pleased with the volumes we've seen so far. The fifth element of our growth strategy is to support population health in data analytics and extended care services. Payers understand the value of the lab data and how it can help them improve their members' health outcomes. This has strengthened our value proposition as well. We're also growing revenues from pharmaceutical customers. Quest Clinical Trials Connect, which we launched in 2018, is helping pharma and CROs recruit patients for trials faster, better, and more efficiently. The second part of our two-point strategy is to drive operational excellence. Our Invigorate cost-cutting initiative has been successful. We see more opportunities ahead.
We are confident there's an opportunity to continue to improve and save roughly 3% on our cost structure, or about $200 million per year, to offset increases in our wage bill, as well as reimbursement pressures. At a recent Investor Day, we identified a number of areas for improvement, such as reducing denials and patient concessions, further digitizing our business, continuing to standardize and automate, and optimizing our lab and Patient Service Center networks. Given the increased reimbursement pressure in 2019, we're also closely managing our cost structure. We are rebalancing our resources by reducing expenses in some areas while ensuring we have the operational resources needed to deliver on the volume increases we expect this year. Let me turn it over to Mark, who will take you through our financial performance and our 2019 guidance in detail. Mark?
Thanks, Steve. In the fourth quarter, consolidated revenues were $1.84 billion, down 1.4% versus the prior year. Revenues for Diagnostic Information Services declined 1.5% compared to the prior year, primarily due to a change in estimate adjustment to increase reserves for net revenue on accounts receivable that we previously highlighted in November. I will share more on this in a moment. Volume, measured by the number of requisitions, increased 3.4% versus the prior year. Excluding acquisitions, volumes grew 1.1%. Revenue per requisition in the fourth quarter declined by 5.5% versus the prior year, driven primarily by the reserve adjustment and increased denials and patient concessions. For the full year, price headwinds were consistent with our expectations of slightly less than 1.5%. I'd like to provide color on the reserve adjustment we made in the fourth quarter. You'll recall, we discussed this at Investor Day.
We recorded a change in estimate to increase our accounts receivable reserves by approximately $35 million. We did this based on the following: unexpected increases in coverage denials and patient responsibility, and a billing system conversion in one of our regional labs that resulted in timely filing denials and impacted our ability to precisely estimate reimbursement rates. Because these items were not typical with our historical experience, we monitored them and, in accordance with our process, increased our reserve levels. I am confident in our current process, and we have tightened the level of precision around this complex estimation going forward. Before moving on, I'd also like to provide an update on the headwinds to our Prescription Drug Monitoring, hep C, and vitamin D test categories that we've been discussing over the prior couple quarters.
In Prescription Drug Monitoring, we saw an increase in restricted payer policies that impacted both volume and reimbursement. We lapped denials for two of the more significant payers in the fourth quarter. In 2019, we continue to expect PDM reimbursement challenges as payers seek more clinical evidence to support coverage. Turning to hep C, as we noted previously, AbbVie's hepatitis C therapy reduces the need for genotype testing. While market share of this therapy continues to grow modestly, we expect to lap the most significant headwinds by the second quarter. Finally, in vitamin D testing, higher payer denials impacted both volume and revenue in 2018. One national payer implemented a more restrictive policy last March, which we expect to lap in Q1, but we expect continued pressure on vitamin D testing in 2019.
Moving on to the remainder of our fourth quarter results, reported operating income was $220 million, or 12% of revenues, compared to $269 million or 14.4% of revenues last year. On an adjusted basis, operating income was $271 million, or 14.7% of revenues, compared to $317 million or 17% of revenues in the prior year. Reported EPS was $0.92 in the quarter, compared to $1.82 a year ago. Note, the prior year quarter included a tax benefit recorded as a result of the Tax Cuts and Jobs Act. Adjusted EPS was $1.36, down approximately 3% from $1.38 last year. Cash provided by operations was $1.2 billion in 2018 versus $1.18 billion in 2017. Capital expenditures in 2018 were $383 million, compared to $252 million a year ago. Now turning to guidance. We are providing the following outlook for 2019.
Revenue is expected to be between $7.6 billion and $7.75 billion, an increase of approximately 1%-3% versus the prior year. Reported EPS expected to be greater than $5.16 and adjusted EPS to be greater than $6.40. Cash provided by operations is expected to be approximately $1.3 billion, and capital expenditures are expected to be between $350 million and $400 million. There are several considerations that I will now review for you to think about in 2019. First, as we've shared previously, we are facing more than $200 million of reimbursement pressure this year. This headwind is expected to be relatively evenly spread throughout the year. Second, based on the factors I discussed earlier, the fourth quarter of 2018 should create an easy compare in the fourth quarter of 2019. Third, our revenue guidance includes more than 1% revenue growth from M&A that has already been announced and executed.
Fourth, as Steve mentioned, our volumes are off to a good start this year, and we expect them to continue to build throughout the year. Finally, we are incurring incremental costs in the first quarter to support the volume growth from our expanded network access. We're also tightly managing our cost structure and have undertaken a restructuring in the first quarter of 2019 that will begin to yield savings starting in the second quarter. As you think about the first quarter, we have approximately one less revenue day. To remind you, denials and patient concessions increased throughout 2018, and we are assuming these headwinds carry into 2019. Taking these into consideration with some of the items I just highlighted, we expect revenue to be flat to down in the first quarter, while adjusted EPS is expected to be similar to the adjusted EPS we reported in the fourth quarter.
I will now turn it back to Steve.
Thanks, Mark. Well, to summarize, Quest is well positioned in 2019 to grow revenue and earnings. Our in-network status now extends to approximately 90% of the commercially insured lives in the United States, and volumes are off to a good start. Our guidance for 2019 reflects reimbursement pressures offset by strong volume increases and continued execution of our Invigorate program. Now, we'd be happy to take any of your questions. Operator?
Thank you. We will now open it up for questions. At the request of the company, we ask that you please limit yourself to one question. If you have additional questions, we ask that you please fall back in queue. Our first question today comes from Ross Muken with Evercore. Your line is open.
Good morning, guys.
Good morning, Ross.
As we look at sort of the fourth quarter and kind of what's implied in the first part of 2019 and then over the balance of the year, I guess, as you think about sort of the state of the lab market in general and some of the reimbursement headwinds you're dealing with and then the flexibility of your cost structure, I guess, in terms of your thesis for the business, obviously, there's a lot of things that occurred toward the end of the year that were challenging for you guys. Yet, there's a lot positive happening on the volume side.
I guess, how do you sort of put it all together for us so we can kind of be confident that, clearly, the challenges we saw in the back part of this year, you've sort of dealt with and now are reflected accurately, so that we've sort of found a rebasing side. Then what could you point us to kind of over the balance of this year, that we should be looking for to kind of judge that the jump off into hopefully 2020 and beyond, I guess, is going to be better? Because, obviously, you had a tough fourth quarter. The Q1 is supposed to be a bit weaker, and Mark, you walked through that, and then we sort of recover. So I'm just trying to get a sense for confidence in some of the moving parts and your sort of evolved thesis here.
Well, let me start, and I'll then turn it to Mark. Thanks, Ross, for your question. To start, we'd go back to what we shared with you on Investor Day. We still believe, as the market leader, we have a tremendous opportunity to gain share. I think we just announced the kickoff of our journey to pick up share, and it starts in 2019. We also coupled 2019 with the most significant reimbursement that this industry has ever seen, reimbursement cuts. It's muting some of the share gains that we're going to pick up this year. What we told you at Investor Day, there's two parts of our market share gains, is one is we do believe we can accelerate M&A, and we're actually targeting for 2% growth through M&A.
What we said in our guidance, we only will put in our guidance what we have seen so far closed, so it's roughly 1% in the guidance for 2019. Second is we will see organic growth, and we have to pick up some volumes to be able to offset that reimbursement pressure. When you go through the math, we believe there's an opportunity for us to pick up share in 2019, and that will continue in 2020. The second part of this is the setup for what's going on in the industry, and I'll come back to those three points again. One is PAMA's hurting all of us, but it's going to hurt the non-market-leading laboratories much more significantly. We believe this will be a catalyst for further consolidation.
Second is, with our better-than-ever access changes, payers are working proactively with us on how they do a better job of managing our category of spend. Finally, as consumers are pushing back on their physicians, pushing back on their employers, and asking questions about the best value in the marketplace, and we are the best value in the marketplace. Best quality, the best service at the lowest price. Ross, we have really kicked off 2019 with the beginning of a journey here to pick up share, and we believe with confidence that we can deliver on that outlook that we outlined at Investor Day. Mark, would you like to add to that?
Yeah, sure, Steve. Ross, as I mentioned, and we've talked about several times, including Investor Day, this year saw more dramatic changes throughout the year than certainly any one I've experienced since I've been at Quest. Denials were a big part of that. I'll start with the vitamin D change back in the second quarter. We saw more and more state Medicaid programs making decisions to deny cystic fibrosis. We've talked about Prescription Drug Monitoring and the payers both tightening policies around same day of service for presumptive and definitive testing, which we think is clinically appropriate, but they put in policies to deny payment for one of those tests. We've seen them squeezing panels, saying that they're going to pay for fewer and fewer analytes, and again, we don't think that's necessarily clinically appropriate, but that is the way many of them are paying now.
Even in the area of allergy, there was an NCCI edit that was put in last year that resulted in significant denials in our allergy space. It was a tough year from a denials perspective. We have built all that into our 2019 guidance. When I talked about carrying the fourth quarter business into Q1, we fully accounted for all that in our thinking and the guidance that we're providing. The other area of surprise was patient concessions. Based on what we knew going into the year, we're expecting a similar level of patient concessions. I'm sure you've seen, and we referenced the Kaiser report that came out about the middle of the year that informed us and others that actually the average deductible went up significantly, so there was more being borne by patients.
Obviously, that meant more of our revenue was coming from patients, and we were just starting to see that in our collections, because there's obviously a delay in the adjudication process with payers. We obviously send the bills out to the patients, so we start to get an experience of the collection rate that may or may not match our historical rate and was actually finding that it was being negatively impacted. The other thing I mentioned was we did have some issues with one of our lab conversions. We have done a number of these that we've shared. We're getting close to the endpoint in the standardization process. This particular lab was not a legacy Quest system. It was a system we had acquired a couple of years ago as part of an acquisition.
We therefore did not do as well with this conversion as we did historically, and therefore, we struggled, as I mentioned, with some filing deadlines and other things. The other issue is this is in a geography where historically there's a higher rate of patient concessions versus other geographies. As we got delays in our ability to send out bills, and as we pushed more and more to patients and less directly to the payers, that definitely created a headwind. The good news on that one is we fully expect that to be behind us, and so that's more of a temporal issue versus the denials, which as I said, and the overall level of patient responsibility will carry into 2019 and is fully baked within our guidance.
Our next question comes from Patrick Donnelly with Goldman Sachs. You may ask your question.
Great. Thanks, guys.
Good morning, Patrick.
Morning. Steve, maybe just on the United trends. I know you gave some color. You guys are expecting a first tranche to move pretty quickly. Can you just talk through how it's come in relative to expectations, and then any way you can frame the expectations for the year would certainly be appreciated in terms of what's being.
Yeah, sure. What I said in my prepared remarks, it's off to a good start. We expected that it would be off to a good start. It's on our expectation that we expected to be able to pick up some of the volume early in the year. What we also said is that it will continue to build throughout 2019, and also this provides us a growth opportunity beyond 2019 into 2020, into 2021. Okay? When I talked about a billion dollars worth of opportunity, we'll see a portion of that in 2019, and that's contemplated in our guidance. There is a large portion of that a billion dollars beyond 2019. It's tracking well. We're happy with the early volumes we see, and it will continue to build throughout the year.
Our next question comes from Ralph Giacobbe with Citi. You may ask your question.
Thanks. Good morning.
Morning.
Just, Labcorp had sized an incremental $30 million headwind from Medicaid related to PAMA. Are you seeing similar as the-- I think you said over $200 million of reimbursement headwind seems a little bit worse than what you previously estimated. Wanted to understand that. If you could, real quick, you talked about incremental cost in the first, I think you said in the first quarter. Hoping you can just size that, and whether that does go away for the rest of the year. Thanks.
Yeah, Mark?
Sure. Ralph, the $200 million is actually consistent with what I shared at Investor Day. The amount of PAMA headwinds outside the Clinical Lab Fee Schedule where we're directly reimbursed from Medicare on fee for service is not large. There's some Medicaid programs that have reduced their rates. They may have justified it or cited PAMA changes. It's hard to know whether these Medicaid rates are directly tied to PAMA. You can look across all the states. There seems to be potentially some direct relationship. Not all of them have changed the rates. Yeah, there's a little bit of headwind in Medicaid, as there typically is. That's not unusual, certainly not to the magnitude of the amount that you asked us about.
Then we're not going to size the investment specifically, what we wanted people to understand is when you look at the rhythm of the quarters coming to the year, on the cost side, not only do we not benefit from the restructuring of our cost base that we announced at the end of this quarter until Q2, we also are actually spending more in Q1 as we're making people aware of our new access in all of the geographies where we need to inform patients and providers. We're betting on the combo, adding Patient Service Centers, extra couriers, doing all the things to ensure that as this volume comes, the customer and stakeholder experience is outstanding. Obviously, we'll continue to monitor that as we see the volume and either add more or less.
Initially, when you add that a little bit ahead of the volume, it's cost versus cost of sale. That's really what we wanted to make sure people understood. The other significant item in terms of the quarterly cycling, as I mentioned, is one fewer revenue day. That is significant. We pick it up in Q3. Losing a day of billing in Q1 versus last year is going to be a significant impact in the year-over-year comparison.
Thank you. Our next question comes from Bill Quirk with Piper Jaffray. Your line is open.
Morning, Bill.
Great. Thank you. Good morning, everyone. A couple questions here. First off, on vitamin D, real quick, just want to confirm that this is lower volume versus, say, pressure on reimbursement levels. Also on the Medicaid denials, was hoping you could expand on that a little bit, because it's pretty much universally covered, at least based on our due diligence. Lastly, just big picture question for Steve. Based on our conversations, how much volume from the hospitals do you think could be in play for M&A over the three-year PAMA period, initial PAMA period? Thank you.
Yeah. Gotta.
Mark, why don't you take the first two?
Yeah. The Medicaid denials. And I'm not sure what you're referencing, Bill, a combination of managed Medicaid, where they put in more restrictive requirements, including pre-authorization, that often can result in denials. Also, some of it arguably clinically appropriate, where they put in new intelligence to ensure that women only have this once in a lifetime. They may have had this done by a different lab historically. We obviously weren't aware of it. We get an order, we think it's legitimate, we do the work, we provide it to the payer, and they deny it based on a once-in-a-lifetime policy. Those things are absolutely tightening in cystic fibrosis. We have had a couple of states, I don't have it at my fingertips. We'll circle back and do that. Actually, the state programs with traditional Medicaid that have stopped reimbursing cystic fibrosis as well.
On vitamin D, as I mentioned, it was a combination. Certainly, we still continue to get and got orders with screening codes. Quite often, vitamin D is ordered as a part of a bunch of other common laboratory testing. We don't choose to not perform that test, even if the diagnostic code initially is not one that suggests we get reimbursed. It absolutely is a headwind to our revenue per req, and has resulted in significant denials with the change in this national payer. Also, as physicians have gotten educated on the appropriate use, and certainly we're driving that, the industry is driving that, you have seen a fall off because some of the vitamin D that was being ordered was for screening, and clinically, that has been determined not to be appropriate.
There still is a number of vitamin D tests that are coming through in screen codes that really are not screening. The doctors just are not coding them appropriately, and unfortunately, those are resulting in denials and headwinds for us.
Yeah. Bill, in your question about the opportunities around hospitals, let me start by reminding you and everyone that what we said in Investor Day is in 2018, we had a strong year for M&A. It was about 300 basis points roughly. If you recall, if you go back to one of those Investor Day slides that we used and charts we used, if you look at the distribution of the M&A we've done over the past two years, it's really been a balance of acquiring hospital outreach, acquiring some outreach deals, excuse me, some laboratory regional deals, and then finally buying some capabilities and services and advanced diagnostics. If you look at the hospital deals, it's been a good part, but not the majority of what we have acquired. Then second is we still pick up, let's say one regional lab per year.
Matter of fact, we just said in our prepared remarks that we closed on Boyce & Bynum in Missouri. That's a good example of doing that once again. What we also indicated is prospectively, we do believe based upon what we see in our pipeline for all three categories, is that M&A should be north of 2% going forward. We also said we've only contemplated in our guidance something around 1%, which are those deals for 2019. Some portion of that is the acceleration in the discussions we're having with hospitals around their lab strategy. When we have those discussions, Bill, we also have discussions around professional laboratory services, and that's an organic growth opportunity.
We announced, again in our prepared remarks, that we picked up two engagements in the back half of 2018 that we feel good about, and we have more engagements in the pipeline as well. You need to think about our hospital strategy really from a contributor to M&A to get to that 2%, but also equally the opportunity organically to pick up organic revenue growth through these professional laboratory services engagements that we continue to announce.
Thank you. The next question comes from Lisa Gill with JP Morgan. You may ask your question.
Good morning, Lisa.
Good morning, Steve. Good morning, Mark. I just really wanted to make sure that I understand how we're thinking about the cadence of earnings this year. If I look at 2018, it looks like roughly 52% of earnings came in the front half, 48% in the second half. It sounds like it's going to be vastly different in 2019. Am I thinking about that correctly, that we're going to see a lot more of the earnings come in the third and fourth quarter, just based on all your commentary, whether we think about the incremental day in the third quarter, we think about anniversarying hep C, as well as vitamin D, as well as some other things. That would just be the first part of my question.
Secondly, also along those lines, Steve, you made this comment around the volume to build throughout the year as it pertains to the managed care contracts. Can you maybe just give us some color? Is that you're educating the physicians around being in networks? What are some of the things that will have to happen throughout 2019 to give us comfort that you will see that volume?
Okay, Mark, you first start.
Yeah. I'll start with the quarterly cadence, Lisa. Yes, you're correct. As we look at 2019, as I mentioned, Q4 should be, and we expect to be, an easy compare to 2018 given the significant change in estimate that I referenced. Also, Steve will comment more color on this in a minute, we expect volumes to build. While we certainly moved a bunch of offices and got incremental access volumes at the beginning of the year, we're continuing to compete, and we expect to build more and more over time. We also have referenced and are anticipating and hopeful that United will announce this preferred lab network, and we're hoping to be included in that. We're expecting to be. We're awaiting that announcement. We think that'll benefit us as well, certainly with United patients.
Yes, we have probably not gotten as much into the calendar impact on quarterly cycling in the past, but it is so significant. We're going to provide more transparency. Losing a day in the first quarter, gaining a day in the third quarter certainly will change the year-over-year impact. That is not insignificant. Finally, as you mentioned, some of the timing of what we incurred, some of the headwinds last year and when we lap those, and that will not happen in Q1, therefore we have a tougher compare year-over-year in Q1, combined with the cost items that I mentioned earlier. For all those reasons, the compare is much tougher in Q1. The last thing I would add is patient concessions.
As we mentioned at the beginning of the year, we did not anticipate a significant shift to patients away from the payers directly on where our revenue would come from. Now that we saw what happened last year, we are building in a higher rate of patient concessions from day one. Obviously, over time, as we look at our collections, we will adjust that. That's certainly going to be a headwind in the first quarter as well. All of those things are built into the guidance that we provided for the year.
Just to fill out the question around volume growth throughout the year and the first tranche in the first quarter. What we shared in 2018 is when we announced that we were going to be back in-network with United and Horizon and with Anthem in Georgia, we started to communicate that to our customers. What we will see in the first quarter is the first tranche, if you will, of those really good customers request, that they wanted us to get back in the network, and we're ready to flip those accounts as quickly as possible. You'll see that. Second part of this is why it's going to continue to build, is not everyone is flipping on day one. It provides us an opportunity for the rest of 2019, and then into 2020 and 2021.
Some of this is that some of the market is still hearing firsthand from us that we're back in-network. To answer your question, what do we need to do is we continuously work on communication. We do this with our sales force. It takes multiple calls to the customer to be able to flip those accounts, typically. Sometimes we need to work out some of the IT integration issues to make sure we can get those orders and also result those from some customers that might be relatively new. That just takes some time. If you take the state of New Jersey, where essentially we're back in-network with the Blue Cross Blue Shield system in New Jersey and with United, we pick up a lot of access.
We've got a number of accounts that we're detailing to pick up significant share, but those take more time than maybe where we only had, we didn't have 10% of the volume of those loyal customers in that first tranche. That's what we're going to need to do, and we'll do in the back half, and that will continue in 2020 and 2021, where we still see more opportunities to pick up share.
Thank you. Our next question comes from Jack Meehan with Barclays. You may ask your question.
Thanks. Hi, Steve. Hi, Mark.
Hey, Jack.
Hey, Jack.
I had a couple of, just hoping for some details on both the rev per req and volumes in the quarter. On rev per req, down 5.5%. By my math, the accounts receivable change was about two points. If you could bridge us on the remaining, what some of the factors are, that would be helpful. On the volume side, how much did M&A contribute, and the moving pieces between weather and calendar would be helpful.
Are you asking weather and calendar in Q4, Jack? Or just.
Yep, all related to the fourth quarter.
Okay. The other drivers of revenue per req include things like mix. For instance, our PLS business, which as we've explained in the past, has a lower revenue per req, had a higher growth rate than our overall core business. That created some headwinds on our rev per req. What I referenced in terms of the fact that the business experienced an increasing level of denials throughout the year, and also patient concessions relative to the prior year. Those things all made it a tough compare year-over-year, Q4 2017 versus Q4 2018. It wasn't just the change in estimate, it was actually a recognition that that business had a lower revenue per req as we were exiting the year. Those are some of the contributors. We certainly had a little bit of weather impact.
It wasn't significant, but it was a headwind in that as well. In terms of days, it was a small impact, small negative impact as well. The other thing was that we had some price changes in the back half of the year that will annualize in 2019 before the end of the year. You combine all those things, and those certainly were the drivers in the year-over-year decrease in rev per req.
Thank you. Our next question comes from Kevin Caliendo with UBS. You may ask your question.
Morning, guys. Thanks for the call.
Hey, Kevin.
I just wanted to go over the United, the preferred network. You made the comment that you hope to be included, and I would assume that you're planning on being included given that you're now in-network. If you can clarify that comment a little bit, that'd be helpful. Also, I just want to understand what you think is going to actually happen within the United network come July 1. What actually changes within United behavior, within their member behavior? If you can sort of quantify that'd be really helpful.
Yeah. Sure. First of all, one would think when we announced in May that we're back in-network with United, and we're the nation's largest commercial laboratory that, if in fact United were to go forward with a preferred laboratory network, then we would be included. It's up to them to announce that, but we're clearly hopeful and planning on being one of the short list of laboratories that are included. In that, what we share with that, in the past, is that all payers, and particularly United, I think in my mind is taking the lead on this, is realizing that they could do more to do a better job in laboratory spending. By having a preferred laboratory network, they're going to tighten up the network, and they will work with us on things that we can do to make sure that we drive market share gains.
That would include things like working with their customers, their ASO customers, on benefit designs. It could include working with us on our hospital strategy, where it could be in the best interest of all parties to think about a different network strategy within a geography. It also could include things that we're proactively going after certain geographies where we know there's an opportunity for us to gain share. Can't announce it before it's announced, but we're hopefully will be included, as you would expect we should be, given we're the largest national and given that we just announced we're back in- network. There'll be a lot of strategies within us to help us with our market share gain plans that we've outlined through the course of the last 6-9 months. Mark, you like to add to that?
I think that covers it. Obviously, we're respectful of United's desire and right to announce. We've applied for that lab network. There's a certain set of criteria, as we looked at it, we're very confident, but ultimately, we need to wait for United. Then in terms of what the particular aspects are, I think Steve captured it well. Largely, it's whoever's preferred, you're preferred for a reason. Obviously, it's better value, but it's also quality metrics and other things that United's looking for their members. Therefore, United, the patients, and everybody else in the ecosystem who is in that preferred lab network will all benefit if there's more work sent to those better value providers.
Thank you. Our next question comes from Ricky Goldwasser with Morgan Stanley. You may ask your question.
Morning, Ricky.
Good morning. Two questions. Let me start with the payer one. When you listed the factors that had a negative impact on price in 2018, you talked about payer denial that started in March, one national payer, and it's going to lap in the first quarter. What gives you confidence that other national payers are not going to follow the lead of the specific one? Have you had conversations with payers, and have you factored in that risk in your guidance range?
Yeah, Ricky, thanks for the question. Actually, a majority of the payers are already there. In the managed Medicare space, they've been following MLCP for a while, and that's really where this emanated from. Cigna adopted it in 2018. The last remaining significant payer who hasn't moved there yet is Aetna. We obviously have a very close relationship with Aetna. We expect Aetna to move in that direction, and certainly that is built within our assumptions. We don't know exact timing. We don't know for sure, but certainly in our assumptions and in our guidance, we're expecting Aetna to go there as well, and therefore, all the national payers to be there.
Thank you. Our next question comes from Ann Hynes with Mizuho Securities. Your line is open.
Morning, Ann.
Good morning. When I look at your free cash flow guidance, it looks pretty strong despite the reimbursement headwinds. Can you let us know what is embedded of that free cash flow guidance? Is it how much share repurchase is embedded? How much is slated for M&A? Secondly, typically you provide a guidance range, and you're just doing a minimum this time. Is there a reason for that? Maybe what are the biggest swing factors that could get you higher than that minimum range? Thank you.
Sure, Ann. The guidance on operating cash flow, $1.3 billion, is obviously commensurate with our expectations around growth and earnings. There's not a significant change in working capital assumed within those numbers. There's other puts and calls around some tax items and so on and so forth that impact our operating cash flow that we've taken into account. Largely, the change year-over-year is based on our net earnings. In terms of cash deployment, I talked about the $350 million-$400 million for internal capital, which obviously leaves you somewhere between $900 million and $950 million of free cash flow. Our dividend now gets us to a long way towards our majority commitment to our shareholders, but certainly we need to do some share repurchases to get ourselves to that least 50% commitment.
That is built into our expectations to basically, at this point, prevent dilution given our equity program. We're not anticipating in that guidance that I provided a pickup from any reduction in waste. With the remaining free cash flow, it's going to be situationally dependent. As Steve talked and I mentioned, we have an M&A strategy. We expect to deploy a chunk of that cash. We're coming into the year with some good carryover based on deals that we've already executed, but we just announced the closing of Boyce & Bynum.
Beyond that, we believe there's opportunity to deploy more in M&A, we're going to use the same financial discipline we always have. If we have a deal that we know in mind will create more value for our shareholders, we're going to move forward on that deal. If, at a given point in time, we don't have any executable deal that meets our expectations, we will buy back shares as we have historically. At this point, I don't have a specific plan for the balance of the year beyond our majority commitments and obviously beyond the cash that we're deploying for the Boyce & Bynum acquisition.
Thank you. Our next question comes from Brian Tanquilut from Jefferies. Your line is open.
Hey, good morning, guys.
Good morning.
Morning. Steve, just a question for you. As we talk about payers consolidating market share to the top players, on your competitor's call, they talked about Blue Cross of Florida as a payer that they're having conversations with. Is that something that we should start thinking about? If you just could give us some details on that contract in terms of expiration and the setup that you have with them right now. Thanks.
Yeah. Brian, as we've done in the past, I'm not going to give you a specific comment on a specific payer. What we have said is that we're in very nice shape entering 2019 with our relationships. What we will say is that, going into 2019, we should have most of the nationals in good shape. We obviously are there with United, we're there with Aetna, the others we'll be in nice shape as well. Also in these big states, matter of fact, we talked about at our Investor Day, we're particularly strong in the biggest states in the United States. If you look at California, if you look at New York, Florida, and Texas, about 110 million lives, our share is very strong, our relationship with the other payers in those states are quite strong. We feel good about that.
We're in nice shape in those states. That is true, to go back to your specific question about Florida, we feel good about our presence in Florida. We have a strong working relationship with Florida Blue Cross Blue Shield, and we feel we're in a nice position to deliver on picking up share that we talk overall about doing as Quest Diagnostics in the state of Florida because of that relationship and our great assets that we have in Florida.
If I could just jump in real quick. I didn't answer the second part of Ann's question, my apologies, before we jumped to Brian. Ann and others, the reason we've chosen to give a floor instead of a range this year is given some of the uncertainty this year, obviously, to make the call on how quickly we grow that volume, we move access. It's not a negative uncertainty, it's just more variability than we've experienced historically in terms of how the volume might come, where it will come from, et cetera. The guidance we're providing with the floor, obviously, is towards the lower end of our revenue guidance. To the extent that we hit the upper end of our revenue guidance or even potentially surprise ourselves and beat that, those would be the upside. I think we've got our cost down pretty good.
Really, the question is around the overall volume growth, the pace at which it comes, and the source of which lives, because obviously there's variability in the pricing and margin depending on which payer they come through. That would be the opportunity to do better, and hopefully, that answers your question on why we chose to give a floor instead of a range.
Operator, next question.
Thank you. Our next question comes from Derik de Bruin with Bank of America Merrill Lynch. Your line is open.
Hi, good morning. Thanks for taking my call.
Hey, I certainly have seen my out-of-pocket diagnostics costs creep higher now that I'm getting some work done on a regular basis. I may not have noticed this if I was doing a one-off or annual visit. I guess, how do you drive consumers to shop around for their diagnostic vendor when they're at the hospital? If you're told to go to the hospital lab to give a sample, at what point can you intervene, or can they intervene to ask Quest to run the test? It's basically, how do you give that consumer the choice to send it to a lower cost provider if the hospitals aren't telling you to go there?
Yeah. Excellent question. We've been on raising awareness for consumers around the wide variation in medical costs broadly. Related to that, it is a multi-prong approach. First of all, in some states, we actually provided this at Investor Day, the states are actually providing visibility of the wide variation for consumers. In the state of Massachusetts, they're actually providing it on a website. If you go on that website, you'll see the wide variation of what the average commercial rates for Quest Diagnostics are versus hospital outreach laboratories. The hope is, in that state, since consumers are picking up a fair share of the cost of healthcare, that consumers will start to become aware of this and bring that information to their physician.
The second part of this is physicians are the advocate, typically, for the patient, even though they have this relationship with the hospital systems. In some cases, they sell their practice. Still, they realize that this is coming out of their patient's pocket. They realize there could be wide variation, which for a number of patients, it's a considerable sum of money. For those of us who are reasonably healthy, it might be once a year, but for many, it's not once a year. It's a considerable portion of out-of-pocket costs. We're making sure the physicians are aware of this as well. When you look at what we're doing with the payers, the payers are going to increasingly make it visible.
The payers all reach out to their membership and have campaigns with simple messages like, why pay more? Related to that, it's not just the lab. I know many of you realize there's other ancillary services that you have the same issue. For instance, radiology is getting a lot of visibility. The help we're getting here as well is this topic in general is getting a lot visibility for payers, but equally from physicians, and then with consumers asking questions. Once they realize they can ask the question, they demand that they know they could come to Quest, we're in-network, and therefore it's unacceptable that you tell them they can only go to the hospital lab. They simply point to, "It's going to cost me extra money if I don't go to Quest. Doc, why does this make sense?" That's what we're doing about it.
Thank you. Our final question today comes from Matt Larew with William Blair. You may ask your question.
Hi, good morning.
Morning.
I wanted to ask about your referral partners. You mentioned, Steve, that volumes had trended nicely through the first quarter. I just wanted to get a sense for what of that you attributed to potential share gains versus increasing healthcare utilization at the end market level. Thanks.
Yeah. First of all, we're here in, we're only, I guess February 14th. Happy Valentine's Day. What we see in the first five or six weeks of the year, as we said, we're off to a good start. We haven't been asked about it, about share. We think utilization volumes are stable. We're not seeing big pickups or drops in our good customers, therefore, we think utilization environment out there is relatively stable. Therefore, the volume is coming from share gains, and that's what we expected. Good start. We're picking up share, and that's going to build throughout the year. Operator?
We are showing no questions in queue.
Okay. Thanks everyone for joining us today. We appreciate your support and questions, have a great day. Take care.
