TL;DR

HCPCS J9246 is the Level II code for Injection, melphalan (evomela), 1 mg, billed per 1 MG. The Medicare Part B ASP payment limit for October 2026 is $18.569 per billing unit, up 2.9% from July 2026. The practitioner MUE allows up to 300 units per date of service (MAI 3). Under OPPS it carries status indicator K in APC 9375. With a 1 mg billing unit, a single administration can be hundreds of units; the unit count on the claim must equal the milligrams given, and rounding rules for partial units follow the contractor's guidance. The ASP crosswalk maps 1 NDC to it, sold as Evomela by Acrotech Biopharma LLC. No current Billing and Coding Article lists J9246, so coverage follows the FDA label, compendia and any applicable NCD.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J9246 as a column-1 or column-2 code in v323r0. Drug supply codes are rarely bundled; the administration codes billed with them are where PTP edits usually apply.

J9246 is neither an add-on code nor a designated primary code in the 2026 Q4 NCCI add-on edit file.

Medicare coverage articles

No current Billing and Coding Article lists J9246 in its HCPCS table. Coverage then follows the drug's FDA label, compendia and any National Coverage Determination; check the Medicare Coverage Database before administering off-label.

Hospital outpatient (OPPS) status

In the July 2026 OPPS Addendum B, J9246 carries status indicator K and is assigned to APC 9375, with a published national unadjusted payment of $18.04. Status K means the drug is paid separately under OPPS at the ASP-based rate rather than packaged into the procedure.
