Medicare Part B Drug Average Sales Price

Medicare pays for some separately payable Medicare Part B-covered drugs and biological products using the average sales price (ASP) methodology. Medicare pays most separately payable drugs and biological products at a rate of ASP plus 6%. To calculate the ASP and payment of each drug and biological product, manufacturers submit sales data, including discounts, quarterly through the ASP Data Collection System. CMS publishes the payment amounts each quarter in the ASP Pricing Files. Manufacturers should contact Sec303ASPData@cms.hhs.gov with any questions regarding ASP data submission.
