CMS published information for pharmacies and other suppliers that wish to enroll in Medicare temporarily as independent clinical diagnostic laboratories to help address the need for COVID-19 testing. Medicare-enrolled pharmacies and suppliers seeking to initiate temporary Medicare independent clinical diagnostic laboratory billing privileges should contact the hotline of the Medicare Administrative Contractor (MAC) serving their geographic area. Pharmacies and other suppliers who are not currently enrolled in Medicare and want to enroll as an independent clinical diagnostic laboratory, must submit a CMS-855B enrollment application to the MAC serving their geographic area. See MLN Matters SE20017 for more details.
