ASP Pricing Files

The quarterly ASP Pricing Files are grouped by the year in which they are effective.  For more information on how ASP is reported, and what drugs and biologicals are included in the ASP Pricing Files, visit the ASP Reporting page:

Please Note: CMS does not publish an ASP payment limit or crosswalk for all products that are reported by manufacturers.  Several factors, including but not limited to the setting in which the product is used and its volume in Medicare Part B are evaluated before a decision about national pricing is made.  The absence or presence of a HCPCS code, NDC code, or payment allowance limit in the files does not indicate whether Medicare covers a particular product.  Even if a product does not appear on a quarter's national price file, it may still be paid by the local contractor that processes the Part B claim, provided that the claim is reasonable and necessary and meets all necessary requirements for payment.  In such a case, the local contractor will also determine the payment amount.
