TL;DR

HCPCS J2425 is the Level II code for Injection, palifermin, 50 micrograms, billed per 50 MCG. The Medicare Part B ASP payment limit for October 2026 is $38.839 per billing unit, up 0.4% from July 2026. The practitioner MUE allows up to 125 units per date of service (MAI 3). Under OPPS it carries status indicator K in APC 1696. J2425 is billed in units of 50 MCG; the quantity administered, the NDC package and the units on the claim must reconcile, which is the check that prevents CARC 16 and 151 returns on this line. The ASP crosswalk maps 2 NDCs to it, sold as Kepivance by Swedish Orphan Biovitrum AB (PuBL). No current Billing and Coding Article lists J2425, so coverage follows the FDA label, compendia and any applicable NCD.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J2425 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.

J2425 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 J2425 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, J2425 carries status indicator K and is assigned to APC 1696, with a published national unadjusted payment of $38.69. Status K means the drug is paid separately under OPPS at the ASP-based rate rather than packaged into the procedure.
