What CMS found
In a Feb. 27 notice, CMS said Elevance failed to delete diagnosis codes not supported by medical records for dates of service from 2015 through April 2023, did not report and return the resulting overpayments within 60 days, and sent its corrections on encrypted USB flash drives rather than through CMS systems. The agency also said Elevance’s annual data certifications were inaccurate. The sanctions cover 45 contracts and would suspend both enrollment and communications to beneficiaries.
Elevance can avoid them by submitting the required corrections through CMS systems and having its senior official attest by March 30. The company disclosed the notice on March 2, said it revised its practices in April 2023 and is engaging with CMS. Its shares fell 9% that day. Elevance enrolled about 1.9 million seniors in MA for 2026.
Why this reaches the hospital
Hospitals are not party to the sanction, but they will feel its effects.
- Payer mix. If the freeze takes effect, seniors in your market who would have picked an Elevance plan will go to other MA plans or traditional Medicare, shifting volume across contracts with different rates and rules.
- Documentation scrutiny. CMS is targeting diagnoses without chart support. Expect MA plans to press harder on provider documentation, coding audits and retrospective record requests.
- Denials and downcoding. Insurers under compliance pressure often tighten payment review. Track denial rates and appeal turnaround by plan.
- Contract leverage. A plan facing growth limits may be more open to value-based terms, or more aggressive on rates. Know which before your next renewal.
The broader signal
This is not the first time CMS has frozen a major MA carrier. Cigna faced similar sanctions in 2016, and analysts note it lost about 14% of its MA members the following year. What stands out here is the scope of the findings, which reach back across most of a decade of risk adjustment data. Hospitals that have treated MA risk coding as the plans’ problem should assume documentation quality will become a bigger part of payer relationships.
