The HHS' Inspector General's Office released audits of nine Medicare Advantage plans over the last six months, according to the organization's semiannual report to Congress, published Dec. 5.
The OIG audited medical coding records for diagnoses considered "high-risk" for upcoding. Medicare Advantage plans have faced allegations of upcoding members' medical records to make them appear sicker, thereby receiving more payments from CMS.
Here are the audits, published between April and September 2022, summarized in the semiannual report. The audits found over $72 million in total overpayments.
1. People's Health Network
The Louisiana-based payer received $3.3 million in overpayments in 2015 and 2016, OIG said.
2. Cariten Health Plan
The Humana subsidiary received $9.9 million in overpayments in 2016 and 2017, the agency said.
