CMS: Most hospitals with outreach labs required to report private payer clinical laboratory data by July 31

Most hospital outreach laboratories must report private payer clinical diagnostic laboratory data for services furnished during the first six months of 2025 to the Centers for Medicare & Medicaid Services by July 31, the agency announced. This includes Healthcare Common Procedure Coding System codes, associated private payer rates and volume data. CMS previously sent letters to hospitals, which the agency believes have outreach laboratories that are likely required to report their data. CMS also has a guide and other resources for hospital outreach laboratories to determine whether and how they must report.
