The Medicare Part B ASP payment limit for October 2026 is $0.768 per billing unit, up 0.7% from July 2026. The practitioner MUE allows up to 48 units per date of service (MAI 3). Under OPPS it carries status indicator N. J2700 is billed in units of 250 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.

NCCI edits and add-on relationships

No active practitioner PTP pair lists J2700 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.

J2700 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 J2700 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, J2700 carries status indicator N. Status N means payment is packaged into the associated procedure and no separate OPPS payment is made.
