TL;DR

HCPCS A9587 is the Level II code for Gallium ga-68, dotatate, diagnostic, 0.1 millicurie, billed per 0.1 mCi. CMS publishes no ASP payment limit for it; hospital outpatient departments are paid separately under OPPS (status indicator K, $49.63 per billing unit in October 2026). The practitioner MUE allows up to 54 units per date of service (MAI 3). Unlike most diagnostic agents, which OPPS packages into the procedure (status N), A9587 is paid separately in the hospital outpatient department (status K). Other HCPCS codes whose descriptor names gallium ga-68: C9067 (CMS descriptor names "dotatoc"; billed per 0.01 mCi). The OPPS crosswalk maps 1 NDC to it, sold as Netspot by Advanced Accelerator Applications USA, Inc. No current Billing and Coding Article lists A9587, so coverage follows the FDA label, compendia and any applicable NCD.

Medicare payment: OPPS rate (no ASP limit)

A9587 does not appear in the October 2026 Part B ASP payment limit file. CMS pays it separately to hospital outpatient departments under OPPS with status indicator K in APC 9056, at a national unadjusted rate of $49.63 per 0.1 mCi. Status K is a separately paid, non-pass-through drug or biological, including therapeutic radiopharmaceuticals. In a physician office the Medicare contractor prices the drug, often from invoice; commercial and Medicaid payers set their own rates.

NDC to HCPCS billing-unit conversion

The October 2026 OPPS crosswalk maps 1 NDC from 1 labeler to A9587. Report the NDC in the claim's drug segment and bill the number of A9587 units that equals the quantity administered divided by 0.1 mCi; the last column gives units per full package.

Medically Unlikely Edits (MUE)

MUE for A9587 in every setting opens the lookup with this code filled in, next to any other code on the same claim.

NCCI edits and add-on relationships

No active practitioner PTP pair lists A9587 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.

The counts above are exposure, not answers for a specific claim. Check A9587 against another code to see whether a given pair bundles, which code is paid and whether a modifier can separate them.

A9587 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 A9587 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 October 2026 OPPS Addendum B, A9587 carries status indicator K and is assigned to APC 9056, with a published national unadjusted payment of $49.63. Status K means the drug is paid separately under OPPS rather than packaged into the procedure.

Ambulatory surgical center (ASC) payment

In the October 2026 ASC Addendum BB (covered ancillary services), A9587 carries payment indicator K2, which CMS defines as "Drugs, biologicals, and radiopharmaceuticals paid separately when provided integral to a surgical procedure on ASC list; payment based on OPPS rate". The national ASC payment is $49.63 per 0.1 mCi, paid only when the drug is furnished integral to a covered surgical procedure.
