Thank you, Stephanie. Good afternoon, and thank you all for joining us. Doug Devine, our Chief Operating Officer and Chief Financial Officer, and Daniel Wilson, our EVP of Corporate Strategy and Development, join me on today's call. My prepared remarks today cover progress we've made throughout the first half of 2022 and discuss the near and long-term growth initiatives for our business. I'll then turn the call over to Doug to provide a detailed review of our second quarter financial results. Starting with our second quarter results, we were pleased with the performance during the quarter, with revenues up 10% sequentially and 26% year over year, and we achieved record quarterly registrations amidst a difficult market environment. Our top-line results were ahead of expectations and position us well for the second half of 2022 and beyond.
We also continue to make progress in driving an increased focus on operational discipline, delivering nearly 200 basis points of sequential improvement in our gross margin profile. In our core U.S. commercial business, we achieved another record of quarterly registrations driven by an all-time high number of new accounts doing business with us in the quarter, with new account openings in the second quarter up 22% compared to the first quarter of 2022. Our volume performance outperformed the market year-to-date, driven by our strong growth in primary care and other specialty segments as we continue to grow our overall share of the market.
While we realized our highest level of daily registrations ever in the month of June, we have already seen seasonality typical of the summer months, and there continues to be clinical staffing shortages and a challenging macroeconomic environment, which we anticipate will continue through the back half of the year. On the pricing front, we shared last month that CMS published their proposed calendar year 2023 physician fee schedule, which contained proposed payment rates for the two main CPT codes related to long-term continuous ECG monitoring. In the proposed rule, CMS published data that implies payment rates ranging from $207 to $295 across the company's three IDTFs. We estimate that proposed rates will have an immaterial impact on our overall ASP in calendar year 2023 versus calendar year 2022.
We are now in a public comment period that runs through early September before CMS issues a final rule anticipated in early November for implementation on January 1, 2023. During the open comment period, we are continuing to fully participate in the rulemaking process to share relevant information as CMS finalizes their rates for calendar year 2023. Turning to updates on the innovation front, we were excited to announce that we gained 510(k) clearance for the clinically integrated ZEUS system for the Zio Watch. This is an important early step in expanding our platform to more patients who may benefit from preventative and proactive cardiac monitoring. The ZEUS system, produced in partnership with Verily, combines deep learning algorithms with our proven and trusted ECG monitoring service in a clinical-grade, long-term, non-invasive wearable device.
Using a continuous PPG AI-based algorithm, the Zio Watch not only detects AFib, but also characterizes the amount of AFib over time to calculate an AFib burden estimate with accuracy comparable to the Zio XT patch as a reference. This contextualization of patient AFib presence or absence collected through the monitoring period is important and clinically meaningful to aid in a potential diagnosis. With full integration into our Zio Service, the Zio Watch is intended to be complementary to Zio monitors by adding a modality with longer wear times for patients who require long-term monitoring. We plan to introduce the ZEUS System for a limited market evaluation in 2023. Another highlight of our ongoing product innovation efforts, the Zio monitor, our next-generation biosensor, has demonstrated an initial positive impact on patient compliance following an initial launch several months ago.
While preliminary, we are encouraged by the impact that this lighter, smaller, and thinner form factor could potentially have on our patient's experience, while also providing opportunity for greater manufacturing and scalability efficiencies. We continue to anticipate full-scale commercialization and conversion to this next-generation device in 2023. Finally, we were excited to launch a new clinical resource center on our website to enable clinicians centralized access to clinical evidence, on-demand webinars, and case studies. This resource serves as a gateway to published clinical evidence, offering summaries of significant research as well as a list of more than 35 clinically relevant published articles to support the clinical validity of Zio. Furthermore, a webinar library hosts on-demand educational videos featuring respected physicians and clinical staff discussing the impacts and outcomes of their experiences with Zio.
Our case study section offers evidence illustrating how the Zio Service has helped healthcare systems improve cardiac patient care. Turning toward progress against the pillars that we have identified for our future success, I'm excited that we have rounded out our executive leadership team to include a number of new individuals, which we believe will be important for growth and transformation of the business in the coming years. Dr. Mintu Turakhia, our recently appointed Chief Medical Officer and Chief Scientific Officer, has hit the ground running in his first two months to drive innovation, lead research and evidence generation, and enhance our clinical vision. Chad Patterson, who joined the company as our new Chief Commercial Officer in late July, has extensive experience driving revenue growth through strategic sales and marketing execution in global markets, which will be leveraged as we expand geographically and into adjacent spaces.
Reyna Fernandez has also recently joined iRhythm as our Chief Human Resources Officer to develop and lead implementation of strategies to support our global growth imperatives, bringing a wealth of experience in leading HR functions in large global organizations, as well as companies with fast-paced, high growth-focused environments. Finally, we are also excited to have Brice Bobzien join us on August 8 as our new Chief Financial Officer to guide our organization through financial and operational transformation, as well as help position the company to scale internal processes as we prepare for future growth. I'm very excited to welcome these seasoned leaders into our leadership team and look forward to executing on our vision of building iRhythm into a market leader in the digital healthcare space.
Finally, we are also pleased to announce that we will hold an Investor Day on the morning of September 21st in New York City for analyst investors of the company. This half-day event will focus on key elements of a refreshed vision, renewed long-term business strategy, details of our growth pillars, and long-range financial targets. We appreciate that investors and stakeholders have been asking for greater granularity on these topics, and we are excited to be able to host this event in person as well as via live video webcast. In conclusion, we finished the first half of 2022 having made steady progress against our goals and in a strong position to capitalize on the sizable opportunities ahead of us to serve millions more patients.
We see significant runway for growth within our core market that we serve today as we continue to shift the standard of care to Zio, the gold standard in this space. With more than $200 million of cash on the balance sheet and a clear path to being profitable, we continue to invest in our mid and long-term initiatives that will leverage our technology platform in new geographies and across new markets. We are excited about our future here at iRhythm. I'll now turn the call over to Doug to discuss our financials.
Thanks, Quentin. Our second quarter results demonstrated the strength of our business as revenue grew 26% year-over-year and 10% quarter-over-quarter. Registrations and new account onboarding continued growth and new stores again contributed strongly to our growth. Taking a more detailed look at our second quarter financial results on a sequential basis, revenue increased 10% quarter-over-quarter from $92 million to $102 million. We had strong growth in the number of new accounts onboarded, increasing by 22% from first to the second quarter. Average volume from new accounts was flat from the first quarter to the second quarter. Looking at new store, same store mix, new store defined as accounts that have been opened for less than 12 months accounted for 38% of our year-over-year growth, down from 55% in the first quarter of 2022.
XT home enrollment was about 20% in the second quarter, approximately flat compared to the first quarter. Turning our attention to the rest of the P&L, gross margin for the second quarter was 68.8%, a 1.9% increase from gross margin of 66.9% during the first quarter. Increases in volume and a reduction in average unit cost contributed to stronger gross margins during the second quarter versus the first quarter. Second quarter adjusted operating expenses, net of restructuring, were $93.5 million, up 12% from the first quarter and up 29% year-over-year. Non-recurring costs related to executive transitions and professional services contributed to the increases in operating expenses. Adjusted EBITDA of -$5 million during the second quarter was down 0.2 million versus adjusted EBITDA of -$4.8 million during the first quarter.
Cash and short-term investments declined $4.3 million from the first quarter to $204.5 million. Adjusted EBITDA losses were the primary uses of cash. Accounts receivable increased by $2.1 million to $57.4 million from $55.3 million in the first quarter, primarily driven by the increase in revenue from the first quarter to the second quarter. Net loss was -$23.9 million or a loss of $0.80 per share compared to a net loss of -$17.4 million or $0.59 per share in the same period of the prior year. Turning to updated guidance for 2022, we expect full year revenue to range between $415 million and $420 million, reflecting year-over-year growth of 29%-30%.
We expect gross margin to range between 68% and 69%. We expect operating expenses to range between $375 million and $385 million, and we expect adjusted EBITDA to range between -$12.5 million and -$17.5 million. The adjusted EBITDA will exclude restructuring costs and will continue to exclude stock compensation expense. We continue to anticipate adjusted EBITDA break even or better by the fourth quarter of 2022. Looking at the third quarter, we expect volumes to be approximately flat to the second quarter due to continued staffing limitations with providers and high levels of patient and provider vacations in the July and August time frames.
As previously stated, we expect to see about $7 million of benefit from the NGS pricing in second half 2022, roughly evenly split between the third and fourth quarters. With that, Quentin, Dan, and I would like to open the call for questions. Operator?
Thank you. We will now start today's Q&A session. If you would like to ask a question, please press star followed by one on your telephone keypad now. If you change your mind, please press star followed by two. Just to remind you all that we ask that you ask one question with one follow-up. When preparing to ask your question, please ensure your phone is unmuted locally. Our first question today comes from Cecilia Furlong from Morgan Stanley. Your line is now open.
Thanks for taking the question. This is Calvin on for Cecilia. Congrats on a good quarter. Two from me. I wanted to start with a two-part geographic volume shift question. So with national pricing kind of now potentially in place for 2023, A, I wanted to confirm your plan of shifting volume over time to San Francisco. You know, is perhaps a two-year timeline a reasonable timeframe as you think about executing the shift of claims and human capital? And, B, you know, is the plan to shift a portion of the claims to the NGS region throughout, you know, the balance of this year like you previously planned and then redirect those to San Francisco sometime next year? Or would that MGM portion just kind of stay in Illinois more on a permanent basis?
Yeah. Well, thanks for the question. Appreciate it. I think my answer will address both of those questions in one response. If not, follow up with a clarifying question, feel free to. You know, I think one of the greatest benefits that we have with getting a final rule put in place is that for the first time, we're able to effectively really manage across all three of our IDTFs in the most operationally efficient manner possible. We haven't been able to do that historically. Now that we have a final rule coming into place, that's gonna allow us to do that in a way that we just haven't historically been able to do, which means, you know, processing through Houston, processing through Chicago or Lincolnshire, and also processing through the San Francisco location.
We're excited by the opportunity that gets created from that perspective. Keep in mind, you know, more than half of our volumes come from the western part of the United States today. Naturally being able to serve those, you know, locally to those IDTFs or that San Francisco IDTF is advantageous to us. We certainly are excited by that. We will continue down the path with NGS over the course of this year. I think that just naturally takes advantage of the capacity and what we have built out there or have been building out there throughout the rest of this year. I would expect volumes will continue to remain there into next year as well. I think that will continue to be a part of how we operate into the future.
Thanks. Very helpful. If I could just add a quick follow-up. Looking forward to the September Analyst Day, I was wondering if you could talk a little bit about your outlook for just the support for silent AF reimbursement from here, on the heels really of Guard-AF likely not providing statistically significant results just given the enrollment. Thoughts on how this ultimately shifts payer momentum, shifts USPSTF guidelines or, you know, could endpoint CE data be a needle mover or something else? Thanks so much.
Yeah. Look, we're very excited with the progress that continues to be made in the silent AF efforts in our Know Your Rhythm program in the discussions with many of the commercial payers and different potential partners that are out there. We'll share a lot more around that at the Analyst Day, but I will tell you, we're excited by what we're seeing. We're excited by the engagement from a payer's perspective with respect to how we're positioning the program, how we've designed the program.
In terms of longer term reimbursement, you know, I think that's gonna continue to take some time to build up and create evidence with, but I do see it on the commercial payer side, something that's very interesting and quite a bit of engagement with our partners that are out there, and look forward to sharing much more of that in the Analyst Day.
Great. Thanks so much.
Our next question today comes from Allen Gong from JP Morgan. Your line is now open.
Hey guys. For my first question, I kind of just want to have a follow-up to the question on the IDTFs. You know, given the kind of preliminary guide you gave at the time of the proposed rule release, it sounds like, you know, you are planning to have a mix of IDTFs, or at least you're gonna have volumes going through a mix of IDTFs through 2023. When we think about, you know, longer term, say out to 2024, it sounds like, you know, you see some benefit to maintaining some level of volumes at all three of the IDTFs that we're talking about through, you know, Texas, Illinois, and California. Is that going to be continuing out into 2024, or do you plan to shift predominantly all of your revenues to San Francisco, given the favorable GPCI there?
Yeah, Allen, I think, you know, that's something that we'll continue to evaluate into the future. Having the ability to leverage all three IDTFs now, unlike, you know, what we've been able to do historically, is gonna give us the opportunity to see where we're most efficient and how we can most efficiently manage through, you know, volumes into the future. We're expecting significant growth in this company as we think about the terrific opportunity that exists in the core market, just to move this to the standard of care, but then to expand into the primary care channel. There's tremendous volume growth that's gonna sit in front of us.
How we're best, you know, served or positioned to serve that volume demand as it comes is something we'll evaluate over the course of 2023, and we'll talk about 2024 as we get closer to it. I guess what has me most excited is for the first time, we can really begin to leverage the operational efficiency that exists in the company, better than what we have historically. We're looking forward to that.
Got it. I appreciate that, the Zio Watch won't be launching until next year, or the ZEUS. When we think about kind of its role in the portfolio, how should we think about it playing alongside, you know, your current launch of the next-gen patch in symptomatic AF? How should we think about, you know, the role of it in asymptomatic? Because I think, when investors were originally contemplating the watch, they were thinking of it as maybe a solution for asymptomatic, given the longer wear times. Thank you very much.
Yeah, thanks, Allen. I'll ask Dan to comment on that. I can jump in as well. Dan, you wanna comment on it?
Yeah. Yeah, thanks, Allen, for the question. I can start here, and Quentin can add anything that he'd like to add. You know, we're excited about Zio Watch and excited about the potential that it adds to our portfolio. As we look, you know, at the market, we see a clear gap in terms of, you know, between kind of long-term monitoring as it's defined today, between, you know, 14-30 days, and then longer-term, you know, the only real option out there today is ILRs, which is an invasive procedure. We see a clear opportunity for a non-invasive clinical grade long-term monitoring platform like Zio Watch and we're excited to have achieved regulatory clearance and getting that into the market next year.
We do see a number of clinical use cases both, you know, on the symptomatic and potentially on the asymptomatic side. We'll certainly share more details around that in terms of how we are evaluating those opportunities and prioritizing those opportunities as we get closer to market. Certainly see, you know, opportunities for that, for Zio Watch in our portfolio and in the market.
Thank you. Our next question comes from Joanne Wuensch from Citi. Please go ahead.
Good afternoon, and thank you for taking the question. Seems to me like we're gonna be talking more about the international opportunity, and it also seems to me some of your new hires may be more targeted to that. Could you just sort of give us a mile high view of how you think about that contributing, maybe not this year, but over the next couple of years?
Yeah, sure, Joanne. Certainly international for us is a meaningful opportunity that I think we've just begun to scratch the surface with the presence we have in the U.K. You know, as we've shared before, we'll start market access efforts in a select number of countries in the back part of this year, notably Netherlands, Switzerland, Germany, France, Sweden. Those are some of the particular countries on our roadmap. Each one of those countries have a little bit of a different with respect to getting reimbursement in place. But I think the right way to think about, you know, revenue contribution is really probably 2024. I think you'll see market evaluations, you'll see us begin to do a bit of work with products getting both into country in the back part of 2023.
I think that's really gonna be less about more of a market evaluation sort of effort, and then ramp in that 2024 timeframe. Hopefully that brings us through from a timing perspective, how we're thinking about it. I think as we get into 2023, we'll continue to explore other opportunities that are out there. You know, we are moving forward with Japan, the largest HCM market in the world. We expect to submit for full regulatory approval in the not too distant future. What we see there, that's probably a 2024 timeframe as well. Right now it's feeling like 2024 is the right timeframe to really start to think about some contribution, but you'll hear more about it over the course of 2023 for sure.
As a follow-up, do you think that the reimbursement is in place in most of these markets, or do you think you'll have to go to bat for that there? Thank you.
No, you know, what's interesting is, you know, ambulatory cardiac monitoring is in place in each of those countries. There's reimbursement established already. The Holter monitor's incredibly popular there. The challenge is how do we articulate our value differentiation and clinical distinction relative to those offerings? That's what the market access efforts are for. Reimbursement is there in terms of monitoring. It gives us a platform to start from and then to articulate our value and work for different reimbursement levels is really what we're focused on. We're not gonna have to articulate the need for monitoring. That's understood, which is a big part of why we selected the countries that we did select, to be quite honest with you.
Thanks. Our next question comes from Margaret Kaczor from William Blair. Your line is now open.
Hi, this is Brandon on for Margaret. Thanks for taking the question. Congrats on a great quarter, and I wanted to talk a little bit about the new openings. You know, in the past, we used to talk about individual cardiology practices and that kind of going into IDNs. You guys obviously had a great and record quarter of new account openings. Can you talk a little bit about what those new accounts look like? Where are you guys kinda focused right now? Where is the demand coming from? What the potential size of these are and volumes and how they ramp?
Yeah, sure, Brandon. We continue to make great progress in the cardiologist sort of specialist EP space with respect to new account openings. We haven't really seen that trend line change from historical sort of levels of the last several quarters or so. But what we're seeing is that the interest level in the primary care physician space and some of these other specialties is elevating up. You know, we've talked very specifically around the fact that we have a high degree of confidence that you're gonna see the primary care physician begin to utilize this sort of technology in their practice.
Not only is it our point of view. When you talk with payers, they also articulate the fact that they believe more and more of this sort of monitoring is gonna find its way into that primary care space.
That was the last one we heard there from one of the speakers. Would any other speaker like to take over that question, or would you like me to ask the next one?
Sorry, are you not able to hear me?
I can hear you, Quentin.
Okay. I'll continue on. If you can, please interrupt me. The point is, you know, we've got a strong belief that the primary care physician space will open up, and we're seeing that begin to be validated in our new account openings, where a higher and higher mix is coming from that primary care channel. It's validating our belief, our thesis, that that will be a significant space for us into the future. I do believe the average size of a primary care physician office in terms of the prescribing levels is gonna be less than what you see in the cardiologist space. I see that. I think that's why, you know, we've seen a pretty good level of average volume from new accounts be pretty consistent. Doug mentioned that.
It does put a little bit of pressure on that just 'cause I think the PCP office is a bit smaller. There's a lot more of them, but they're a bit smaller. We're mindful of that. I think we need more experience, to be honest with you, to really identify just what the right average volume is there, and so I'm not gonna comment on that just yet. We're very excited by the momentum that's being built in that primary care space.
Great. In terms of, Quentin, you've been bringing on a lot of new, experienced leadership, obviously with great backgrounds. Kind of curious, as you look at the organization and we look forward a couple of years, what kind of commercial changes do you think that iRhythm that needs to make? You've been homegrown for several years. This wasn't really a story that kind of, quote, unquote, "needed fixing." Perhaps you have identified the things that could take you to the next level, and you've brought in some management to do that. What are some of those opportunities that you've seen, and what can we expect in terms of commercial or operational changes over the coming years? Thanks.
Well, look, I'm excited to have the leadership team finally set. You know, we have with us around the table who we're going to battle with for the future now, and I'm excited to be able to really get after it from that perspective. We've added a lot of global capabilities and incredibly strong commercial experience set from different perspectives. You know, one that has experience with med device, you know, sort of medical background, but also blending the lines with consumerism, which is where I think the future of this sort of technology will go and continue to blur those lines, and so that excites me. When you look at it, I think there's a couple different things from a commercial perspective.
We have to continue to evolve the model here in the U.S. that allows us to continue to pursue the primary care physician space. I think that's done in multiple ways, not just simply putting feet on the street. I think the marketing aspect becomes a much bigger part of who we are and how we move forward and how we create awareness. Not only awareness, education that articulates why we're unique and different just versus any other monitoring capability that's out there because we truly are differentiated with our AI capability, the algorithmic efforts that have been put forward and the data that stands behind our products. So we've got to continue to elevate our ability in that sense. I think you will see us evolve in the U.S. marketplace.
Then, internationally, every market's a little bit unique and different. I think that, you know, how we approach that, having skills around our leadership table who have been there before, have seen what success looks like there, is only gonna position us for greater success and faster success. I'm excited to see what that looks like as we move into the future. We're in the middle of understanding exactly what that design looks like as we go. We'll talk more about it into the future, but we now have a capability in the organization that I believe meets up very well with the opportunity that sits in front of us.
Great. Thank you.
Our next question comes from David Rescott from Truist Securities. Your line is now open.
Hey, guys. Thanks for taking my question. Congrats on the strong quarter. First, just on Zio AT. I guess the first part of the question is, you know, is that product at all or has that product at all been having a positive impact as it relates to opening the new accounts that you saw in the quarter? And I think in the past, you know, you've discussed how the product is, you know, 14-day wear device, whereas the majority of the market and I believe reimbursement, you know, kind of covers this longer 30-day wear monitor devices. Can you just talk about what the maybe future iterations of that device would be and how that would open up the market to you guys?
Sure. You know, today we hold, I would call it, you know, mid-20s in terms of sort of market share of the overall ACM market. Yet we're probably around 7% when we think about the MCT space or where AT really can play, and it just speaks to the opportunity that sits there from a product perspective. In terms of new account openings, you know, it has the opportunity to open some new accounts. The vast majority are being opened with XT, and AT happens to get pulled into it sort of after the fact. It's not the lead into many of these new account openings. I believe there's that opportunity into the future, but today XT is really continuing to be that door opener.
In terms of the product configuration itself, you know, 14 days versus 30 days, we understand there's a difference there. The reality is in 30 days of monitoring, though, you're gonna get on average about 12 really good days of feedback and data that you're paying attention to and monitoring. With our 14-day product, you're gonna get 14 good days of monitoring. I think there's a little bit of education that needs to continue to be had and made on our part. I also think there are some things we can do from a product features and functionality that can close that gap down in terms of 14-30 days. We're focused on that effort.
I won't give you any, you know, specifics of exactly how we're looking at that product offering, but we are looking to continue to evolve it and I think become even more effective player in that space where I don't see any reason why we can't hold the same sort of market share there that we hold in the XT business over time, as we continue to educate and close that gap on the product side.
All right. That makes sense. I guess as it relates to the ZEUS, you know, the Zio Watch, I'm just wondering kind of what the differentiation here is between some of the, you know, existing, you know, watches out there that suggest that they could identify at least something similar to what the Zio Watch is going after. Just following up on Dan's comments around potentially maybe going after or looking at a little bit of the implantable loop recorder market with the watch. I guess how do you kind of move into that space or address that space and build or develop the market there? Thank you.
Yeah. Well, maybe I'll let Dan continue on with his response, and I'm happy to take the latter part of how we enter into it. Dan, you wanna comment on that?
Yeah. Yeah, I could start, Quentin, you should chime in. David, I would say the distinction is pretty straightforward as we think about how Zio Watch compares to consumer wearables. Zio Watch and ZEUS is designed as a prescription diagnostic-grade wearable, that integrates into clinical workflows and provides clinical context that is important to patient care and specifically estimating AFib burden. We know that's an important clinical metric for physicians and that's one, you know, that is trusted, as we deliver our Zio service for XT and AT. And that's exactly what we're looking to deliver with Zio Watch as well. It's purpose-built to kind of deliver that same level of service, as Zio XT and Zio AT, and part of that is generating the clinical evidence to back that up.
That is part of our initial efforts as we enter market evaluation efforts next year. Quentin, you wanna continue on from there?
Yeah. No, I think you hit the nail on the head, though. I mean, it's a very different offering, right? and what folks come to love about iRhythm and Zio is the entire offering, including the service component that our Zio Watch will have with it and continue to differentiate and set it apart. In terms of how we enter the space, you know, in many respects, we're already in many of these accounts where ILRs are being implemented or implanted. we have a contact point into the centers. we just haven't had the right solution necessarily or an alternative solution maybe to the ILR.
The interesting thing in that space is our market data would tell us that only 30% of all patients recommended for an ILR will actually have the procedure done, just not wanting to have something implanted in the body. I think we have a tremendous opportunity to offer up an alternative solution to, you know, continuous monitoring over a longer period of time. Could even be over years, you know, if you're wearing the watch over that period of time to compare to sort of the timeframe that an ILR might be implanted for. I like the way we're positioned there. We can continue to do work around how we take it to market, but I think we continue to find different ways, different opportunities for this product to potentially play in the marketplace. That excites me.
All right. Very helpful. Thank you.
Our next question comes from Marie Thibault from BTIG. Your line is now open.
Good afternoon. Thanks for taking the questions. I wanna ask the first one here, and try to level set on what an average sort of, reimbursement rate would be, when you consider the guidance you've given, which you said, you know, immaterial impact on, calendar year 2023 versus 2022. Given there's been so many moving parts, I wanted to try to understand, is that average maybe somewhere around the $250-$275 range? What are you seeing as sort of the average when you think about the Medicare reimbursement rate?
Yeah, Marie, I think it's a good question. I think from a couple different perspectives, the $250 is about the right way to think about it. That's how we've thought about it. When we look out across, you know, the analyst models and how each of you have modeled it, I think on average, the Street's sitting somewhere around $250 as well. I think, you know, that's the right way to think about it, an average rate in 2023, which is pretty comparable to where the average rate stands for 2022. That's how we're thinking about it.
Okay, that's really helpful. I appreciate that. Wanted to go back to your comments on primary care physicians. That's a really interesting potential growth opportunity. Wondering if you have, you know, carved out a portion of your sales force to focus on that market. Is there sort of a differentiation on how you approach those doctors or sort of educate them on how to use the device? Any color there would be helpful. Thank you.
Marie, I think that's where we have the opportunity to really elevate up our ability, our capability, to target those sort of opportunities with the right tools and education. For the time being, you know, most of the progress that's been made there have been our top reps, you know, seeing that as an opportunity and going in and beginning to educate the accounts on their own. We've tried to create that opportunity in the field force by adding what we call key account managers or customer experience managers that maybe will step in and maintain the existing accounts that we have working with us who have been long-term customers and free up the territory manager to go out there and hunt for new business.
What we find is, you know, they're seeing the opportunity in the primary care space, and they're naturally sort of hunting there on their own. That's great to see in terms of the results that we're putting up in terms of the new account openings, but it's also being done without what I think are the most effective and most efficient tools that we can create. I think that's a big part of, you know, bringing in some incremental focus on the marketing side, on the educational side, building out capabilities, investing into our teams that are here. I think you can see us, you know, really make some headway there. We're excited about it, but we're in the early stages. I would tell you there's a lot of progress to be made there.
Very interesting. Thank you.
Our next question comes from Bill Plovanic from Canaccord. Your line is now open.
Hi. Thanks. Good evening. I'm gonna ask a couple of financial questions, if I may. Just, you know, on the guidance, Doug, as we think about, you know, the incremental $7 million, $3.5 million in the third quarter from the NGS, was there any contribution from NGS in the second quarter, or is that up and above what we saw from NGS in the second quarter?
Yeah, Bill. I mean, we certainly ran some test claims through in the second quarter. You know, as we talked about before, we have an existing staff out of the NGS, out of our Chicago, North Chicago office. You know, so that, you know, so think of the $7 million, $3.5 million a quarter as, you know, that's the incremental benefit you're gonna see going forward for the rest of this year.
Okay. Thank you. That's helpful. Just, I was wondering if you could provide us any directional guidance on the levels of growth or any other metrics regarding your payer mix, including the contracted third party, non-contracted CMS and healthcare institutions?
Yeah. Doug, feel free to jump on that.
Yeah. Bill, on that one, you know, when you're looking at it on the year-on-year basis, you're seeing, you know, about 10% more of our mix going to CMS, and that's a combination of two factors. I mean, one is the pricing that you know we're seeing better pricing than we were seeing last year. The second is that, and you know there were some shifts in pricing from Zio AT, and our mix has continued to richen incrementally towards Zio AT as well. You know, we've been working on the non-contracted, so non-contracted has not been. You're not seeing any real growth in the non-contracted segment.
Okay. If I could ask just one last follow-up question, and it's kind of a clarification. You know, you talked about the PCP. I don't know if you talked a lot about the post-TAVR and if you have specialized the reps are doing the same thing where they're kind of focusing on those account and going in. Any clarity on that would be greatly appreciated. Thanks so much.
Yeah, Bill, on that last one, that continues to be an opportunity for us. You know, we're in a very, very small amount of TAVR centers today. I think in terms of priority and focus, it's certainly something that's on our list, and we see it as an opportunity. Primary care has been higher on that list to date. There's not a lot of contribution coming out of the area today.
Thanks for taking my questions.
Mm-hmm.
Our next question comes from Suraj Kalia from Oppenheimer. Your line is now open.
Quentin. Good afternoon, everyone. Quentin, can you hear me all right?
We got you. Yep. Hey, Suraj.
Perfect. Hey, so Quentin, thanks. I know you guys provided a lot of information on the call. Specifically on optimizing IDTFs in 2023 and beyond, Quentin, will there be different technician reviews at the three locations, or is there a set format that you'll anticipate moving forward?
I think that's part of the opportunity that we
The reason I ask.
Yeah. Sorry to cut you. Go ahead.
No, the reason I ask is, you know, just figuring out efficient costs, levels of review, you know, how it impacts the P&L.
Yeah, I think that's exactly sort of the opportunity that we have to evaluate and take a look at now. You know, depending on the complexity of the data that comes off the devices, off of the patients, will identify or dictate what level of review is required, whether it's a more simple sort of review or a more complex sort of review. We're gonna have the opportunity to get how we maximize those efficiencies into the future. There's obviously a different cost of doing business within each one of those IDTFs. Just from a geographic perspective, we've got to contemplate that.
There's different service level that we can offer to our patients in terms of just timeliness of turnaround times when we start to consider, you know, shipping costs and freight costs and those sort of things with the different intake centers or distributions. Those are all things that we've got to evaluate now with our business models. Historically, we haven't had the real opportunity to look at it from the most efficient operational perspective. Max, but on a go-forward basis, having a final rule in place, I think it makes it much easier for us to look at it through that lens and make the right decision for the company.
Quick additional question, and I'll hop back in the queue on ZEUS. Forgive me, maybe I missed this. How do you anticipate billing for ZEUS? I think that would be one part. You're obviously looking at different strategies for market penetration. I heard your commentary about tapping into ILR and MCOT, so on and so forth. You know, I'm curious because ILR, primary users as we understand, you know, whether it's unexplained syncope or convulsive syncope or, it's. You know, there are a bunch of randomized trials that have been done in the space. I'd be curious if that is a route you all are anticipating going, i.e., you know, pouring of the resources for an RCT. Any additional color on billing and/or clinical trials would be greatly appreciated.
Gentlemen, thank you for taking my questions.
Yeah. Yeah, no, thanks for the question, Suraj. I think you hit the nail on the head with the reimbursement aspect. You know, that's one of the pathways we gotta continue to work through, and it's part of, you know, why we talk about a market evaluation out in 2023 versus a whole lot sooner. We know that's a pathway that we've gotta have discussions with payers around and really determine how this fits and how the reimbursement landscape will work. We're evaluating that. I think it looks different depending on the utilization of how the device is used. You know, if it were part of the Know Your Rhythm program, that might be a little bit different than a traditional pathway outside of that.
We've got some learning to do there, but we do think there's a place for this in the marketplace. With respect to ILR, I think, you know, that's just an identification of another opportunity where something like this device could fit. It's early stages. We've got to continue to evaluate, sort of how to compete, how to win in that space and what that looks like. It's early stages. I think we're just sharing some ideas of what gets us excited with that sort of diagnostic capability and that wearable factor, that doesn't exist today in the marketplace. Work to be done, but opportunity as we see it.
Thank you.
Our final question comes from Mike Polark from Wolfe Research. Your line is now open.
Hey, good evening. Thank you for taking the questions. I just wanna make sure I understand the bridge in the current calendar year 2022 guidance. You know, a lot of moving parts on pricing. You know, for the full year revenue growth of, call it 30%, the question really is what's the contribution net from price and volume in that outlook? In the context of initially, I think the Novitas move to 2-3s was a 10% lift. NGS is now coming into the mix. That seems to be another two, three, or four points. It gets me to kinda 12 or 14 points of price.
MCT is experiencing, you know, 20%-30% lift this year in payment rates, and that's another two or three points. I'm kinda like mid-teens total, mid-teens plus total pricing benefit for the year from all this. I just wanna, you know, get the updated view on how you see it and what is embedded in the guidance at this point for full year volume growth.
Sure, Mike, I can speak to that. You know, we came into the year continue to reiterate sort of our views around our volume expectations being around that 20% growth rate from a volume perspective. You're right, when you look at those various price effects, you're getting into call it the mid-teens, lower mid-teens, but you're not meaningfully off. Then we contemplate sort of that low to mid-single digit commercial pricing pressure that we commented on, and I think that continues to be a very accurate way to look at it and model it, which gets you know, down to call it roughly 10% contribution from price on a 20% volume, that's your 30% growth rate.
That's how we think about it, continue to look at it here at the midpoint of the year, and we can update that in the future if we need to.
Appreciate that. Good segue to my follow-up. I'm curious for the updated thinking on, you know, in 2023, proposed rule moves to final. You have a national rate with Medicare. It's, I think, the national average rate's in the $215 zone. So what's the latest fresh thinking on if this moves forward at current proposed rates, you know, is there risk to your rates with Medicare Advantage plans, private payers, or is there not? Any fresh thoughts on that would be welcome. Thank you for taking the questions.
Yeah, you know, we've spent a lot of time looking at this across the payer landscape that we have and understanding sort of what positions we have with the payers, the discussions we're having, sort of the tone of those discussions. I continue to believe the right way to think about it, considering just kind of where things are at and the current price points we have, is that, low- to mid-single-digit, you know, pricing pressure from a commercial payer perspective feels like the right place to be. If we see something that changes or causes us to think differently about it, we'll be happy to talk about it and address it. I continue to believe that's the right way to think about it into the future, and certainly how we're thinking about our models right now.
Thank you. That does conclude today's Q&A session. I will now refer you back to the management team for closing remarks.
Well, look, thanks for joining us today. I wanna make sure that I take the opportunity just to thank our entire iRhythm team for the terrific progress that's been made to date and the momentum that's being built in the business overall. We continue to be excited by the future that sits in front of us and look forward to executing against the goals and the priorities that we've put forward. I look forward to the opportunity to see many of you guys here in September at our Analyst Day, where we'll share much more around many of the exciting things happening here at the company. With that, we'll talk to you in just about a month and a half. Take care.
That concludes today's iRhythm Technologies, Inc., Q2 2022 earnings conference call. You may now disconnect your line.
