How Medicare Advantage plans dodged auditors and overcharged taxpayers by millions

In April 2016, government auditors asked a Blue Cross Medicare Advantage health plan in Minnesota to turn over medical records of patients treated by a podiatry practice whose owner had been indicted for fraud.

Medicare had paid the Blue Cross plan more than $20,000 to cover the care of 11 patients seen by Aggeus Healthcare, a chain of podiatry clinics, in 2011.

Blue Cross said it couldn’t locate any records to justify the payments because Aggeus shut down in the wake of the indictment, which included charges of falsifying patient medical files. So Blue Cross asked the Centers for Medicare & Medicaid Services for a “hardship” exemption to a strict requirement that health plans retain these files in the event of an audit.
