In 2009, James Swoben, a former data manager for California-based SCAN Health Plan, filed a whistleblower complaint against his own employer, and then amended that compliant three times over the next two years to add claims against United Health, HealthCare Partners, Aetna, WellPoint and Health Net.
The Centers for Medicare & Medicaid Services (CMS), administrator of the federal Medicare program, pays Medicare Advantage organizations fixed monthly amounts for each enrollee. CMS calculates the payment for each enrollee based on various “risk adjustment data,” such as an enrollee’s demographic profile and the enrollee’s health status, as reflected in the medical diagnosis codes associated with healthcare the enrollee receives. These diagnosis codes are reported by Medicare Advantage organizations to CMS.
Because Medicare Advantage organizations have a financial incentive to exaggerate an enrollee’s health risks by reporting diagnosis codes that may not be supported by the enrollee’s medical records, Medicare regulations require a Medicare Advantage organization, as an express condition of receiving payment, to “certify (based on best knowledge, information, and belief) that the [risk adjustment] data it submits . . . are accurate, complete, and truthful.” 42 C.F.R. § 422.504(l), (l)(2).
The gist of Swoben’s complaint is that the defendants – Medicare Advantage organizations United Healthcare, Aetna, WellPoint and Health Net, and HealthCare Partners, a physician group providing health care services to the organizations’ enrollees in exchange for a percentage of the organizations’ capitated payments – performed biased retrospective medical record reviews.
According to Swoben, retrospective reviews by Medicare Advantage organizations typically should identify (and report to CMS) two types of errors in the risk adjustment data previously submitted: (1) diagnosis codes supported by an enrollee’s medical records but not previously submitted to CMS (underreporting errors); and (2) diagnosis codes previously submitted to CMS but not supported by the enrollee’s medical records (over-reporting errors). Identifying and reporting the first type of error is favorable to the Medicare Advantage organization; identifying and reporting the second type of error is unfavorable.
Swoben alleges the defendants conducted one-sided retrospective reviews designed to identify (and report to CMS) solely the first type of error. He alleges these reviews were designed to exaggerate enrollees’ health risks and cause CMS to make inflated capitated payments to the defendants. These actions, Swoben alleges, rendered the defendants’ periodic certifications under § 422.504(l) false, in violation of the False Claims Act, 31 U.S.C. § 3729(a)(1).
The district court dismissed the suit without leave to amend The 9th Circuit Court of Appeals reversed and reinstated the claim in the published case of James M. Swoben v United Healthcare Insurance Co, et. al.
CMS has long made clear that, under § 422.504(l), Medicare Advantage organizations have “an obligation to undertake ‘due diligence’ to ensure the accuracy, completeness, and truthfulness” of the risk adjustment data they submit to CMS and “will be held responsible for making good faith efforts to certify the accuracy, completeness, and truthfulness” of these data.
“When, as alleged here, Medicare Advantage organizations design retrospective reviews of enrollees’ medical records deliberately to avoid identifying erroneously submitted diagnosis codes that might otherwise have been identified with reasonable diligence, they can no longer certify, based on best knowledge, information and belief, the accuracy, completeness and truthfulness of the data submitted to CMS. This is especially true when, as alleged here, they were on notice – based on audits conducted by CMS – that their data likely included a significant number of erroneously reported diagnosis codes.”
