On December 29, 2015, CMS released a final rule announcing it will establish a prior authorization process for certain DMEPOS items that are frequently subject to unnecessary utilization.  Though the prior authorization process will require the same information to support Medicare payment, it creates a new requirement that claims for certain DMEPOS items must have an associated provisional affirmed prior authorization decision as a condition of payment. Additionally, the rule adds the review contractor’s decision regarding prior authorization to the list of actions that are not initial determinations and thus not appealable.
