The HHS Office of Inspector General published a Medicare provider compliance audit on September 17, 2026, estimating that Methodist Hospital received at least 12.4 million dollars in net Medicare overpayments.
Auditors reviewed a sample of 100 inpatient and outpatient claims totaling approximately 1.4 million dollars, covering January 2020 through December 2021. Of those, 73 claims complied with Medicare billing requirements. The remaining 27 did not, resulting in 256,926 dollars in identified overpayments within the sample period.
Federal auditors found at least 12.4 million dollars in estimated Medicare overpayments at Methodist Hospital, traced to the hospital not following its own billing policies.
Applying standard statistical projection to the full billing population, OIG estimated net overpayments of at least 12.4 million dollars. During the same two-year period, Medicare paid the hospital approximately 62 million dollars in total.
Auditors found that errors occurred primarily because the hospital did not consistently apply its own written policies and procedures in the billing areas examined.
OIG recommended that the hospital repay the overpayments and provide additional training to clinical and billing staff on Medicare requirements. The audit is part of an ongoing OIG series of hospital-level compliance reviews designed to identify and correct systemic billing errors before they accumulate further.
In plain words
A federal audit found that a hospital called Methodist Hospital got about 12.4 million dollars more from Medicare than it should have. Auditors checked 100 of the hospital's Medicare claims and found billing mistakes on 27 of them. The mistakes happened because the hospital did not follow its own billing rules. The government asked the hospital to pay back the money and train its staff on the correct Medicare billing rules. This type of audit is done regularly at hospitals to find and correct billing errors.
