Medicare pays for separately payable Medicare Part B-covered drugs and biological products using several payment methodologies. Most separately payable drugs and biological products have a payment limit of the Average Sales Price (ASP) plus 6 percent. CMS collects quarterly ASP data from manufacturers through the ASP Data Collection System to calculate the payment limits for drugs and biological products. CMS publishes the payment limits each quarter in the Medicare Part B Payment Limit File. Manufacturers should contact sec303aspdata@cms.hhs.gov with any questions regarding ASP data submission.
