The practitioner MUE allows up to 4 units per date of service (MAI 3). Under OPPS it carries status indicator N. J3411 is billed in units of 100 MG; 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.

Medicare coverage articles

No current Billing and Coding Article lists J3411 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.
