## Abstract

This interim final rule with comment period implements provisions of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 that require the implementation of a competitive acquisition program for certain Medicare Part B drugs not paid on a cost or prospective payment system basis. Beginning January 1, 2006, physicians will generally be given a choice between obtaining these drugs from vendors selected through a competitive bidding process or directly purchasing these drugs and being paid under the average sales price system.
