- The audit found UnitedHealthcare likely inflated Medicare billing claims by at least $46.9 million during the 2020-21 payment period through upcoding of diagnoses.
- Optum and UnitedHealthcare are Minnesota-based subsidiaries of UnitedHealth Group; Optum State Government Solutions is contracted to analyze Minnesota Medicaid claims.
- The audit report was published Tuesday as Optum continues investigations into Minnesota's healthcare programs and Medicaid reimbursement system.
A government audit concluded that UnitedHealthcare’s Medicare Advantage plans received roughly $47 million in improper payments linked to billing practices the watchdog described as upcoding (per Healthcare Dive).
The audit singled out UnitedHealth Group’s Optum unit as playing a role in the plan operations tied to those payments and recommended further review of the business practices (per Healthcare Dive).
UnitedHealthcare is the named recipient of the overpayments in the audit; the report portrays the issue as systemic within Medicare Advantage billing rather than a single-transaction error (per Healthcare Dive).
The audit’s focus on Optum ties the findings to the insurer’s broader vertically integrated structure: UnitedHealth sells coverage through UnitedHealthcare while Optum provides services that support plan operations, and the watchdog raised questions about how those internal relationships affected coding and payment rates (per Healthcare Dive).
UnitedHealthcare and Optum were identified by the audit as central actors, and the watchdog recommended additional scrutiny, though the audit text cited by Healthcare Dive does not, in the excerpt provided, specify enforcement steps or exact remedial actions (per Healthcare Dive).
The timing of the audit reflects growing scrutiny of Medicare Advantage payment practices and the business models of large integrated health companies; the audit frames the $47 million figure as an estimate of overpayments rather than a confirmed repayment total (per Healthcare Dive).
Going forward, auditors urged follow-up review to determine recoveries and any administrative or civil consequences, leaving the final financial and regulatory outcomes unresolved in the published excerpt (per Healthcare Dive).
