NCCI edits and add-on relationships

No active practitioner PTP pair lists J9033 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.

J9033 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 J9033 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, J9033 carries status indicator K and is assigned to APC 9243, with a published national unadjusted payment of $2.96. Status K means the drug is paid separately under OPPS at the ASP-based rate rather than packaged into the procedure.
