Under 42 U.S.C. § 1320a-7k(d), a Medicare or Medicaid overpayment kept past the 60-day deadline becomes an obligation, and the reverse false claims provision reaches anyone who knowingly and improperly avoids such an obligation. CMS rules tie identification to False Claims Act knowledge, so an audit that has already calculated the overpayment becomes a record of what the organization knew. No false claim is needed. Keeping the money is enough.

Abstract

Two 2026 DOJ settlements show how an unfinished internal overpayment audit becomes a False Claims Act case under the 60-day overpayment rule. Covers the overpayment statute at 42 U.S.C. § 1320a-7k(d), the reverse false claims provision at 31 U.S.C. § 3729(a)(1)(G), and the CMS identification rules at 42 C.F.R. § 401.305 and § 422.326. Ends with an operator checklist for open review queues.
