What 96373 covers
This service represents administration of a therapeutic, prophylactic, or diagnostic substance directly into an artery. In a physician office, a physician or clinical staff member may perform the injection as part of treatment or a diagnostic service. The defining feature is the intra-arterial route, including administration through an arterial access device when the drug is injected into the artery; the code describes the administration, not the access device itself.
Select the code based on the documented route and injection service, not the drug name, dose, or reason for treatment alone. The record should identify the substance, the intra-arterial route, the clinical purpose, and who performed the injection. For Medicare, when the service is furnished as an incident-to service, it is billed only when performed under physician supervision. This code is not an infusion-time measure; document the injection performed rather than elapsed infusion time.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

96373 billing questions
How does this differ from 96374?
96373 is for an intra-arterial injection. Use 96374 when the therapeutic, prophylactic, or diagnostic injection is given by intravenous push.
How does this differ from 96372?
96372 describes administration by the subcutaneous or intramuscular route. The route documented for the administration distinguishes it from this intra-arterial service.
What documentation supports reporting 96373?
Document the substance administered, that it was injected intra-arterially, the clinical purpose, and the person who performed the service. For Medicare incident-to billing, the service must be performed under physician supervision.
Is this an hourly infusion code?
No. It represents an injection, not a service selected by infusion duration. Do not use elapsed infusion time as the basis for reporting it.
Can this code describe arterial access or catheter placement?
It describes the drug administration by intra-arterial injection. The documentation should establish that the injection occurred; access or catheter placement alone is not the service represented by this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
