A federal audit recommends that a large Pennsylvania hospital refund an estimated 17.8 million dollars in Medicare overpayments stemming from billing errors identified in a sample of inpatient and outpatient claims.
The Office of Inspector General reviewed 100 claims submitted by Lehigh Valley Hospital between October 1, 2020, and September 30, 2022, as part of an ongoing audit series targeting hospitals with high volumes of claims in categories previously identified as carrying elevated compliance risk. Auditors found that 62 of the 100 reviewed claims met Medicare billing requirements. The remaining 38 did not, resulting in net overpayments of 433,723 dollars within the sample. Projecting from the sample to the full claim population, the OIG estimated total net overpayments of at least 17.8 million dollars.
OIG audit finds Lehigh Valley Hospital in Pennsylvania may have received 17.8 million dollars in Medicare overpayments from billing noncompliance on 38 of 100 reviewed claims.
The audit did not allege intentional fraud. The OIG recommended that Lehigh Valley Hospital refund the estimated overpayments, consider internal audits for claims submitted after the review period, and provide additional Medicare billing training to relevant staff.
The hospital disagreed with most of the OIG's specific findings and with all three recommendations, according to the published report. The OIG maintained its conclusions.
Hospital billing audits in this series are separate from criminal fraud investigations. They are designed to identify systematic errors in billing practices and recover overpayments to the Medicare program. Recovered funds help protect the hospital insurance trust fund that covers older adults and people with certain long-term disabilities.
In plain words
A government auditor reviewed 100 Medicare claims at a Pennsylvania hospital. About 38 of those claims had billing mistakes. Based on those mistakes, the auditor estimates the hospital was paid about 17.8 million dollars more than it should have been. The government asked the hospital to pay that money back and improve its billing. The hospital disagreed with most of the findings. This type of audit looks for billing mistakes, not criminal wrongdoing. The goal is to make sure Medicare pays only what it should.
