TL;DR

HCPCS J0577 is the Level II code for Injection, buprenorphine extended-release (brixadi), less than or equal to 7, billed per Less than or equal to 7 days of therapy. The Medicare Part B ASP payment limit for October 2026 is $433.167 per billing unit, up 0.6% from July 2026. The practitioner MUE allows up to 1 units per date of service (MAI 3). Under OPPS it carries status indicator G in APC 0732. J0577 is billed in units of Less than or equal to 7 days of therapy; 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 4 NDCs to it, sold as Brixadi (weekly dosing) by Braeburn Inc.. No current Billing and Coding Article lists J0577, so coverage follows the FDA label, compendia and any applicable NCD.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J0577 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.

J0577 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 J0577 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, J0577 carries status indicator G and is assigned to APC 0732, with a published national unadjusted payment of $430.58. Status G marks pass-through drug payment, which is time-limited.
