When is it appropriate to assign modifier JF with codes for drugs?


In the July update to the outpatient prospective payment system (OPPS), the Centers for Medicare & Medicaid Services (CMS) included instructions for the following level II code, which took effect on July 1. 

Q9977 Compounded drug, not otherwise classified

In the October OPPS update, CMS noted that this code replaces the use of modifier JF (compounded drug), which has been discontinued. HCPCS code Q9977 should be used to report compounded drug combinations.
