CVS Health (CVS) subsidiary Aetna agreed to pay $117.7 million to resolve federal allegations that it defrauded Medicare through false diagnosis coding, with shares falling 0.5% amid broader healthcare compliance concerns.
The settlement highlights ongoing scrutiny of Medicare Advantage risk adjustment practices that can impact insurers’ profitability and regulatory standing.
Key Takeaways
- Aetna settles $117.7 million Medicare fraud allegations without admitting liability
- Allegations centered on false morbid obesity diagnosis coding practices
- Whistleblower to receive $2.01 million from settlement proceeds
Settlement Details and Market Context
The U.S. Department of Justice said Wednesday that Aetna submitted inaccurate diagnosis codes for morbid obesity and other health conditions between 2018 and 2023 to secure higher monthly payments from the Centers for Medicare and Medicaid Services 1. CVS shares traded down 0.5% following the announcement, underperforming the broader healthcare sector.
Under Medicare Advantage’s risk adjustment system, insurers receive higher payments for sicker patients with more complex medical conditions. Private insurers collectively receive more than $530 billion annually from the government to care for Medicare Advantage patients, according to Assistant Attorney General Brett Shumate 2.
Regulatory Enforcement Pattern
The settlement stems from a January 2024 whistleblower lawsuit filed by Mary Melette Thomas, a former Aetna risk adjustment coding auditor from Arizona. Thomas will receive $2.01 million from the settlement under the False Claims Act’s whistleblower provisions 3.
The case follows a broader Department of Justice crackdown on Medicare Advantage risk adjustment practices across the industry. Similar investigations have targeted multiple major insurers for allegedly inflating patient risk scores to maximize government payments.
Company Response and Industry Implications
CVS said it settled to avoid litigation costs and uncertainty, while maintaining its disagreement with the allegations. “Aetna continues to disagree with the DOJ’s industry-wide allegations, and this settlement should not be seen as an acknowledgment of liability,” a CVS spokesperson said 4.
The settlement represents approximately 0.04% of CVS’s annual revenue, suggesting limited immediate financial impact. However, it underscores ongoing compliance risks facing Medicare Advantage operators as federal oversight intensifies.
Medicare Advantage Market Dynamics
CVS acquired Aetna in 2018 for $70 billion, making it one of the largest Medicare Advantage players. The business model relies heavily on accurate risk adjustment coding to optimize per-member payments from CMS.
“Medicare Advantage relies on accurate reporting,” said Scott Lampert, the Department of Health and Human Services’ acting deputy inspector general for investigations. “Today’s settlement makes clear that no company is beyond accountability, no matter how large or well known” 5.
Outlook
The settlement resolves Aetna’s exposure related to the specific morbid obesity coding allegations but doesn’t preclude future regulatory scrutiny. Medicare Advantage remains a growth driver for CVS, serving millions of beneficiaries nationwide.
Industry analysts expect continued federal oversight of risk adjustment practices as Medicare Advantage enrollment continues expanding. The settlement may prompt enhanced compliance measures across the sector.
