Payment Rate for 340B-acquired Drug Reimbursement Example

Reimbursement Equation is: (ASP Rate/1.06) X 0.775 = Reimbursement

  • January 2018 ASP File Rate for J1453 = 2.047, which includes a 6% markup
  • ASP Rate Converted to 100% is 2.047/1.06 = 1.931132

Beginning January 1, 2018, Medicare pays an adjusted amount of the ASP minus 22.5 percent for certain separately payable drugs that are acquired through the 340B Program and furnished to a Medicare beneficiary by a hospital paid under the OPPS that is not excepted from the payment adjustment policy. For purposes of this policy, “acquired through the 340B Program” means the drug was purchased at or below the 340B ceiling price from the manufacturer and includes 340B drugs purchased through the Prime Vendor Program.
