Medicare Part B Drug Average Sales Price

Manufacturer reporting of Average Sales Price (ASP) data

A manufacturer's ASP must be calculated by the manufacturer every calendar quarter and submitted to CMS within 30 days of the close of the quarter.  Each report also must be certified by one of the following: the manufacturer's Chief Executive Officer (CEO); the manufacturer's Chief Financial Officer (CFO); or an individual who has delegated authority to sign for, and who reports directly to, the manufacturer's CEO or CFO.

For all data submissions made on or after January 1, 2012 (that is, submissions of 4Q2011 and subsequent data), manufacturers must use the 2011 revision of the Microsoft Excel template entitled “ASP Data Form (Addendum A).”  Revisions to the Addendum A template include a validation macro, changes in the layout of the data fields, and new data fields. Additional information about the use of the revised Addendum A template is available in the Average Sale Price (ASP) Data Collection CM Validation Macro User Guide. Both the revised Addendum A template and the User Guide are available in the Downloads section below.  Please note that both documents are pending OMB approval. 

Manufacturers must complete the ASP Certification Form (Addendum B) to certify that their data submissions are accurate, true, and current. Addendum B is available in the Downloads section below; no changes have been made to Addendum B for 2012.

Completed ASP data forms (Addendum A) and certification forms (Addendum B) may be sent to CMS via first class mail, federal express mail, or overnight delivery, at the following address:

Information Regarding Medicare Payment and Coding for Drugs and Biologics (See Downloads section below for additional information)

Section 303(c) of the Medicare Modernization Act of 2003 (MMA) revised the payment methodology for Part B covered drugs that are not paid on a cost or prospective payment basis. In particular, section 303(c) of the MMA amended Title XVIII of the Act by adding section 1847A, which established a new average sales price (ASP) drug payment system.  Beginning January 1, 2005, drugs and biologicals not paid on a cost or prospective payment basis will be paid based on the ASP methodology, and payment to the providers will be 106 percent of the ASP.  There are exceptions to this general rule which are listed in the Medicare Claims Processing Manual, Pub. 100-04, Chapter 17.  The ASP methodology uses quarterly drug pricing data submitted to the CMS by drug manufacturers.  CMS will supply contractors with the ASP drug pricing files for Medicare Part B drugs on a quarterly basis.
