Medically Unlikely Edits (MUE)

CMS does not publish an MUE for J1958 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 J1958 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.

J1958 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 J1958 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.

How QuickIntell checks J1958 before the claim leaves

QuickCode validates the NDC-to-unit conversion against the current ASP crosswalk, checks units against every published MUE setting and flags PTP and add-on conflicts on the same claim. QuickRCM routes CARC 16, 151 and 50 denials on drug lines with the matching coverage article attached so the appeal starts with evidence.
