Medicare coverage articles

No current Billing and Coding Article lists J0360 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, J0360 carries status indicator N. Status N means payment is packaged into the associated procedure and no separate OPPS payment is made.
