CMS Updates Medicare Part B Drug Prices



Retroactive code pricing updates may require claims lookback.

The Centers for Medicare & Medicaid Services (CMS) has posted a retroactive update to the April Average Sales Price (ASP) pricing file for three Medicare Part B drugs. Also now available are the July ASP and Not Otherwise Classified (NOC) pricing files and the ASP NDC HCPCS crosswalk.

April ASP Update

On June 1, CMS retroactively updated the ASP for three HCPCS Level II codes. The updated payment limits are affective April 1, 2021, through June 30, 2021.

J7212Factor viia (recomb sevenfact)1 mcg$2.185
Q5123Riabni injection10 mg$73.83

Take Note

Payment allowance limits subject to the ASP methodology are based on first quarter 2021 (1Q21) ASP data. The absence or presence of a HCPCS Level II code and the payment allowance limits in the pricing files does not indicate whether Medicare covers a drug. Determinations are made by the local Medicare Administrative Contractor processing the claim.

Where applicable, the payment amounts in the quarterly ASP files are 106 percent of the ASP calculated from data submitted by drug manufacturers. The quarter-to-quarter price changes are generally the result of updated data from the manufacturers of these drugs.

According to CMS, comparing the third quarter 2021 payment amounts with the prior quarter reveals that, on average, payment amounts for the top 50 Part B drugs decreased by 0.8 percent. For most of the higher volume drugs (26 out of the top 50), the prices changed 2 percent or less. Overall, the prices for 21 of the top 50 drugs decreased.
