Opinion

MARK HABELT, et al., Case No. 21-cv-00776-EMC

Plaintiffs, ORDER GRANTING DEFENDANTS’ v. MOTION TO DISMISS

IRHYTHM TECHNOLOGIES, INC., et al., Docket No. 55 Defendants.

Lead Plaintiff Public Employees’ Retirement System of Mississippi brings this class action on behalf of similarly situated investors against Defendant iRhythm and Individual Defendants King, Coyle and Devine (current or former corporate officers of iRhythm) to recover damages for Defendants’ alleged violations of federal securities laws. Now pending is Defendants’ motion to dismiss Plaintiffs’ Second Amended Complaint (“SAC”) in its entirety for failure to state claims, pursuant to Fed. R. Civ. P. 12(b)(6). Docket No. 55 (“MTD”). For the following reasons, the Court GRANTS Defendants’ motion. A. Relevant Factual Allegations 1. iRhythm’s Business Defendant iRhythm is a “digital healthcare company that focuses on providing long-term ambulatory electrocardiogram (“AECG”) devices” designed to “diagnose cardiac arrythmias.” Docket No. 54 (“SAC”) ¶ 2. AECG devices can provide up to 14 days of electrocardiographic data which is “scanned and analyzed by [iRhythm’s] cardiac technicians, and then presented in a patch, from which the company allegedly derives “over 85% of its total revenue.” Id. iRhythm’s revenue from the Zio XT patch is allegedly “directly or indirectly tied to Medicare reimbursement rates.” Id. ¶ 3. “At least 25% of the Company’s total revenue was tied to servicing Medicare patients” and the remaining sales to commercial payors were allegedly “indirectly tied to Medicare reimbursement rates” because those customers “typically pay between 1.5 times to 2 times the rate set by the [Centers for Medicare and Medicaid Services (“CMS”)] in a Medicare Physician Fee Schedule (“PFS” released annually.” Id. CMS requires reimbursed services to be billed pursuant to “Current Procedural Technology” (“CPT”) codes, which are assigned corresponding prices. Id. ¶ 4. Prior to 2021, iRhythm billed for its Zio XT service under temporary CPT codes—called Category III codes— which are used for newly-introduced technologies. Id.; MTD at 13. CMS delegates the reimbursement pricing rates for Category III codes to regional Medicare Administrative Contractors (“MACs”). Novitas, the MAC that oversees pricing for iRhythm’s Zio XT services, set the Category III rates for Zio XT between $311 and $316 for several years prior to 2021. SAC ¶ 4, 57. 2. Recommendation of Zio XT for Permanent Pricing and CMS’s Proposed Rule The American Medical Association (“AMA”), which has a role in maintaining CPT codes, recommended that CMS adopt a permanent Category I CPT code for the Zio XT service in 2021, indicating its view that the service had become the “standard of care.” Id. ¶ 56. The process by which a Category III temporary CPT code is adopted into a Category I permanent code involves the AMA’s Resource-Based Relative Value Scale Update Committee (“RUC”) providing a recommendation of pricing to CMS. Id. While CMS “gives weight to the RUC’s input and recommendations, it is not obligated to accept the RUC’s recommendation in the final rule, and it can modify pricing based on its own analysis or delegate pricing to MACs in the final rule.” Id. Based on the RUC’s recommendation, CMS proposed a rule with reimbursement rates of $375.83 and $386.16 for Category I CPT codes for External Extended ECF Monitoring, including the Zio XT, to go into effect in January 2021. Id. ¶ 62. The proposed rule noted that CMS “did (August 17, 2020), allegedly because “iRhythm declined to submit actual invoices, instead providing CMS with insurance claim and cost data that showed only the total cost charged to third-party payors” which includes, among other expenses, the cost of iRhythm’s service to analyze data collected by the Zio XT patch, “without any breakdown of the cost of the different components of the Zio XT,” SAC ¶ 68. CMS observed that rather than receiving traditional invoices, it received alternative forms of pricing information, including a weighted median of historical billed prices for the service, a top-down calculation of the cost of the supply per service, and invoices provided from clinical studies. 85 Fed. Reg. 50165. CMS noted that it requires “an invoice representative of commercial market pricing to establish a national price for a new supply or equipment item,” and, therefore, based on the data that was made available to the agency, it “cannot establish supply pricing based on an analysis of claims data and in absence of a representative invoice.” Id. Instead, CMS proposed to employ a “crosswalk to an existing supply for use as a proxy price until [it obtained] and invoice to use.” Id. CMS explained that although the proxy item it identified was “not clinically similar to the extended external ECG patch,” the agency “believe[d] it [was] the closest match from a pricing perspective to employ as a proxy until [CMS was] able to arrive at an invoice that is representative of commercial market pricing.” Id. at 50165-66. The proposed rule was followed a public notice-and-comment period. SAC ¶ 59, 64. 3. MCDA’s October 2020 Comment On October 5, 2020, MCDA, a healthcare policy and consulting firm based in Washington, D.C., filed a report to CMS as a comment on its proposed rulemaking, urging the agency to adopt a significantly lower CPT Category I price for extended external ECG’s patches, including the Zio XT. Id. ¶¶ 63-99. The report argued (1) that the true cost of Zio XT was less than $100 because iRhythm had folded indirect, un-reimbursable expenses for research and development, and sales and advertising into their costs, id. ¶¶ 65-70; (2) the proxy device CMS relied on for pricing purposes was more complex, and, therefore, an inapposite comparator, id. ¶¶ 71-74; (3) an invoice from a device developed by one of iRhythm’s direct competitors of an allegedly similar device executives in the industry allegedly were aware that the cost of the monitoring device is a small fraction of CMS’s proposed rate and the price of the hardware was trending downwards, id. ¶¶ 94- 96. iRhythm filed a three-page response to the MCDA report which, allegedly, did not contest MCDA’s analysis. Id. ¶¶ 100-03. 4. CMS Final Rule and Pricing for 2021 On December 1, 2020, CMS released its Final Rule establishing payment rates for AECG monitoring devices for the calendar year 2021. The agency, however, declined to set a national reimbursement rate for the devices because it lacked “an invoice representative of commercial market pricing.” 85 Fed. Reg. 84632 (Dec. 28, 2020). The Final Rule acknowledged its decision not to set a national rate was based, in part, on “the conflicting information and assertions provided by commenters” during the notice-and-comment period and declined to establish pricing based on the proxy device it previously identified. Id. at 84633-34. CMS maintained Category I CPT codes for AECG devices, allowing those services to be provided and billed to Medicare patients, but it delegated pricing for those codes to the regional MACs for 2021. SAC ¶ 105. Thus, Novitas remained responsible for determining the reimbursement rates for Zio XT in 2021. Id. Plaintiffs allege that iRhythm’s stock price declined after CMS released its final rule from $240.64 on December 1, 2020 to $180.90 by the end of trading on December 4, 2020. Id. ¶ 106. After CMS delegated the rate-setting decision for 2021 to Novitas, MCDA allegedly published another report arguing that iRhythm’s proposed pricing lacked support. SAC ¶¶ 108-21. Plaintiffs allege their independent expert, Dr. Freeman, independently corroborated MCDA’s analysis. Id. ¶¶ 122-30. On January 29, 2021, Novitas announced reimbursement rates for Zio XT that slashed the historical rate of $311 to a range of average rates of $73.82 to $89.36. Id. ¶ 135. Plaintiffs allege th
