The CMS 2021 ASP Drug Pricing Files for the 4^th quarter effective October 1, 2021 through December 31, 2021 reflects updates for ISTODAX^® (romidepsin) for injection, for intravenous use.  The update includes the following changes which are effective October 1, 2021:

• Discontinued HCPCS Code J9315 “Injection, romidepsin, 1mg” on September 30, 2021 and established J9319 “Injection, romidepsin, lyophilized, 0.1mg” on October 1, 2021.
• Changed the HCPCS Code Dosage from 1mg to 0.1 mg.

Per CMS, this change in J-code needed to be made because: “A new HCPCS code for Romidepsin Injection, non-lyophilized liquid is needed because it is a single source drug approved under a unique NDC number, and it needs to be differentiated from the existing HCPCS code for a multi-sourced Romidepsin drug in lyophilized powder form.”
