Yes, when the injection is a different drug given by a different route (IM or SC) with its own order — and the 96372 line carries XU (or 59), because column 2 of this edit is 96372. A drug pushed into the same IV line is not 96372 at all; that is 96375.
The 96365 / 96372 pair as it stands in the CMS PTP tables for 2026q3 (as of 2026-07-01), identical on the practitioner and hospital-outpatient tables:
96372 (column 2) denies as included in 96365 (column 1) unless the 96372 line carries a distinct-service modifier — XU or 59 — and the record supports a distinct service.
Column 1 96365 · column 2 96372 · edit effective January 2009.
Same edit, same direction: column 1 96365, column 2 96372, since January 2009. A UB-04 carrying 96365 and 96372 is adjudicated exactly as the CMS-1500 is.
The infusion family and the injection family are separate for a reason: 96372 describes a needle into muscle or subcutaneous tissue, not anything that travels through the IV. Billers get into trouble here by coding the route they assume rather than the route in the note. Ketorolac drawn up and given IM while the ceftriaxone drips is a genuine second service; ketorolac pushed through the saline lock is an additional IV push (96375) and 96372 would be wrong on its face.
NCCI pairs 96365 (column 1) with 96372 (column 2), modifier indicator 1, effective since January 2009. The edit assumes the injection is part of the infusion encounter unless you say otherwise, so the 96372 line needs a distinct-service modifier — XU is the specific one (“unusual non-overlapping service”); 59 still works where a payer has not adopted the X modifiers. Medicare contractors apply the edit on both the practitioner and the hospital tables.
On the MUE side both codes are comfortable: 96365 allows one unit per date of service and 96372 allows four (practitioner table, MAI 3), so a second IM injection of yet another drug later in the visit is a second 96372 unit rather than a new problem. What does not work is 96372 for the drug that was in the bag — the infusion code already paid for administering it.
The route decides it, not the encounter: an IM or SC injection is a distinct service from the infusion every time. The test is a route-and-drug test: a different substance, not delivered through the infusion line, with its own order and injection site in the note.
| Code | Descriptor | Practitioner MUE / day | Facility MUE / day | Adjudication · rationale |
|---|---|---|---|---|
96365 | therapeutic/prophylactic/diagnostic IV infusion, initial hour | 1 | 2 | MAI 3 · Clinical: Data |
96372 | therapeutic, prophylactic or diagnostic injection, SC or IM | 4 | 5 | MAI 3 · Clinical: Data |
96365 and 96372 are MAI 3: units are summed across the date of service, and a documented medical-necessity appeal can pay units above the limit. Other codes: MUE lookup.
The 96365 / 96372 answer rests on H10 in the claim builder’s rule set (source: CPT 2026 hydration / therapeutic infusion guidelines · CMS Pub 100-04 ch. 12 §30.5), the rule it applies when it places a line by route:
…a subcutaneous or intramuscular therapeutic injection reports 96372 (96401 chemo/biologic)… Full text of H10

CO-97 or CO-236 on 96372 when it is billed bare with 96365. Add XU to 96372 and resubmit with the MAR showing the IM/SC route. If the “injection” was actually an IV push, correct the code to 96375 — do not add a modifier to a wrong code.

No. An IV push of a second drug during an infusion encounter is 96375 (each additional sequential new drug), an add-on with no PTP edit against 96365 and no modifier. 96372 is reserved for the IM or SC route, and coding it for an IV push is the most common error on this pair.
On the 96372 line only, because 96372 is column 2 of the 96365 / 96372 edit. Use XU where the payer accepts the X{EPSU} set (Medicare does); 59 remains valid as the general distinct-procedural-service modifier. Never put the modifier on 96365.
Yes, as two units of 96372 (the practitioner MUE is 4 per date of service), each with the distinct-service modifier and each drug’s J-code on its own line. Two injections of the same drug at the same time are still one unit.
