CMS publishes 2 MUE values for J2403. For practitioners the limit is 1600 units per date of service with adjudication indicator 2, a date-of-service policy edit: the limit reflects CMS policy and units above it deny even if split across lines; appeals rarely succeed.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J2403 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.

J2403 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 J2403 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, J2403 carries status indicator N. Status N means payment is packaged into the associated procedure and no separate OPPS payment is made.
