CPT code 96368: Concurrent infusion, additional IV substance2026 Medicare rate & RVUs

Medicare pays $20.71 for 96368 nationally in the office. Local office rates run $18.47–$27.67.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 96368 covers

CPT 96368 captures an additional therapeutic, prophylactic, or diagnostic substance running at the same time as another IV infusion, rather than after it. It is used in outpatient infusion settings such as physician offices and infusion centers, where nursing staff typically administer the medications under physician supervision. The code concerns concurrent administration through IV access; it is not a code for an IV push or a subcutaneous infusion.

Report 96368 only with a primary infusion procedure, not by itself. The record should identify the substances, infusion routes, and timing that establish that the administrations overlapped. Distinguish a concurrent infusion from a separate substance given sequentially, which may support a different add-on code. CMS classifies this as an add-on service, with payment included within the primary procedure’s global period. It is an incident-to service and is billed only when performed under physician supervision.
