CMS has released the July 2012 Medicare average sales price (ASP) files, which will be used to pay for Part B covered drugs for the third quarter of 2012.  According to CMS, prices for the top Part B drugs increased by 0.2% compared to the previous quarter, and prices changed 2% or less for the majority of the higher-volume drugs. As it did last quarter, CMS notes that it is authorized to substitute AMP for the ASP in certain circumstances (set forth in the final 2012 Medicare physician fee schedule rule), but the agency is continuing to delay implementation of this substitution policy for “a variety of operational issues.”
