Series: Audits of Selected Independent Clinical Laboratory Billing Requirements

Announced on  | Last Modified on  | Series Number: W-00-24-35726

OBJECTIVE

Medicare covers diagnostic clinical laboratory services that are ordered by a physician who is treating a beneficiary and who uses the results in managing the beneficiary's specific medical problem (42 CFR 410.32(a)). These covered services can be furnished in hospital laboratories (for outpatient or nonhospital patients), physician office laboratories, independent laboratories, dialysis facility laboratories, nursing facility laboratories, and other institutions. Previous OIG audits, investigations, and inspections have identified areas of billing for clinical laboratory services that are at heightened risk for noncompliance with Medicare billing requirements. Payments to a service provider are precluded unless the provider furnishes on request the information necessary to determine the amount due (Social Security Act § 1833(e)). We will review Medicare payments for clinical laboratory services to determine laboratories' compliance with selected billing requirements. We will focus on claims for clinical laboratory services that may be at heightened risk for overpayments. For example, our reviews will focus on the improper use of claim line modifiers for a code pair, genetic testing, and urine drug testing services. We will use the results of these reviews to identify laboratories or other institutions that routinely submit improper claims, including providers that regularly bill Medicare for definitive drug testing at the highest reimbursement amount allowed.

2 REPORT PUBLISHED

23-A-09-045.01 to CMS - Closed Unimplemented
Closed on 04/11/2024
We recommend that the Centers for Medicare & Medicaid Services expand program safeguards to prevent and detect at-risk payments to at-risk providers for the definitive drug testing service with the highest reimbursement amount (procedure code G0483), which could have saved up to $215.8 million for our audit period.

23-A-09-045.02 to CMS - Closed Unimplemented
Closed on 10/01/2024
We recommend that the Centers for Medicare & Medicaid Services review at-risk payments made to at-risk providers during and after our audit period to determine whether payments for procedure code G0483 complied with Medicare requirements and recover any overpayments.

23-A-09-045.03 to CMS - Closed Unimplemented
Closed on 09/24/2024
We recommend that the Centers for Medicare & Medicaid Services notify appropriate providers (i.e., those for whom CMS determines this audit constitutes credible information of potential overpayments) so that the providers can exercise reasonable diligence to identify, report, and return any overpayments in accordance with the 60-day rule and identify any of those returned overpayments as having been made in accordance with this recommendation.

23-A-09-045.04 to CMS - Closed Acceptable Alternative
Closed on 08/31/2023
We recommend that the Centers for Medicare & Medicaid Services educate providers that received payments that did not comply with Medicare requirements for definitive drug testing services.
