TL;DR

HCPCS J3402 is the Level II code for Injection, remestemcel-l-rknd, per therapeutic dose, billed per Per Therapeutic Dose. The Medicare Part B ASP payment limit for October 2026 is $202,159.938 per billing unit, down 0.7% from July 2026. Under OPPS it carries status indicator K in APC 0886. J3402 is billed in units of Per Therapeutic Dose; 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 9 NDCs to it, sold as Ryoncil by Mesoblast, Inc.. No current Billing and Coding Article lists J3402, so coverage follows the FDA label, compendia and any applicable NCD.

Medically Unlikely Edits (MUE)

CMS does not publish an MUE for J3402 in the 2026 Q4 tables. Some MUE values are confidential and applied without publication, so unit limits can still deny; document the dose and the units calculation on every claim.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J3402 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.

J3402 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 J3402 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, J3402 carries status indicator K and is assigned to APC 0886, with a published national unadjusted payment of $203,659.76. Status K means the drug is paid separately under OPPS at the ASP-based rate rather than packaged into the procedure.
