CMS will host a 60-minute webinar on October 14, 2025, at 1:00 p.m. Eastern Standard Time (EST) for Medicare Part B drug manufacturers who are required to submit quarterly Average Sales Price (ASP) data to CMS in the ASP Data Collection System. During this Zoom session, CMS will demonstrate the system to new or recently added users and provide a refresher to highlight any recent system changes for existing users. Additionally, CMS will answer any data entry questions users may have during the required quarterly data submission window. Sign up now on the ASP Events page.
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.
