J9999 descriptor and code status

The October 2026 HCPCS Level II file describes J9999 as “Not otherwise classified, antineoplastic drugs”. It sits in the J section (drugs administered other than oral method and chemotherapy drugs), listed with the other J codes without an ASP payment limit. Although searches often call it the "J9999 CPT code", J9999 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.
