What Aetna’s $117.7M Settlement Means for Documentation

Aetna, a CVS Health subsidiary, has agreed to pay $117.7 million to settle federal allegations that it knowingly submitted inaccurate diagnosis codes to inflate Medicare Advantage payments. The March 2026 settlement highlights growing scrutiny around risk adjustment practices and reinforces the importance of defensible documentation.

What Happened

• Settlement amount: $117.7 million

• Announced by: U.S. Department of Justice on March 11, 2026

• Allegations: Aetna submitted or failed to withdraw inaccurate diagnosis codes for Medicare Advantage enrollees to increase payments from CMS

• Violation: False Claims Act

• Timeframe: Alleged misconduct tied to chart review activities dating back to 2015

Federal investigators found that some diagnosis codes submitted during Aetna’s chart review program were not fully supported by documentation yet were still used to boost risk scores and payments.

Why It Matters for Providers

While the settlement targets a payer, it sends a clear message to the entire Medicare Advantage ecosystem:

• Documentation integrity is non-negotiable

• Unsupported diagnoses can trigger financial and legal consequences

• Plans may increase scrutiny of provider documentation and coding workflows

This case reinforces the importance of clear, defensible documentation — especially for chronic conditions that drive risk scores.
