CS Modifier for Medicare Part B Services
For services furnished on March 18, 2020, and through the end of the PHE, outpatient providers, physicians, and other providers and suppliers that bill Medicare for Part B services under these payment systems should use the CS modifier on applicable claim lines to identify the service as subject to the cost-sharing wavier for COVID-19 testing-related services and should NOT charge Medicare patients any co-insurance and/or deductible amounts for those services.
For professional claims, physicians and practitioners who did not initially submit claims with the CS modifier must notify their Medicare Administrative Contractor (MAC) and request to resubmit applicable claims with dates of service on or after 3/18/2020 with the CS modifier to get 100% payment.
For institutional claims, providers, including hospitals, CAHs, RHCs, and FQHCs, who did not initially submit claims with the CS modifier must resubmit applicable claims submitted on or after 3/18/2020, with the CS modifier to visit lines to get 100% payment.
