Physicians use CPT code 96372 to bill for injections they give under the skin (subcutaneous) or into a muscle (intramuscular). It applies to medications used for treatment, prevention, or diagnosis. This code does not cover IV injections or infusions that have different billing codes.

When to Use 96372

Bundling and Separate Billing

Sometimes, providers include injections as part of other procedures, so they cannot bill them separately. For example, insurers may consider an injection bundled if it occurs during surgery or an infusion service. However, providers can usually bill separately when they give an injection on its own during an office visit. Coders should check payer rules and NCCI edits to confirm.

Frequency Limits and Insurance Rules

Some insurance plans limit how many injections they will pay for per visit or per year. Medicare and private insurers may also require proof that the injection was medically necessary. Always review the insurer’s rules before billing.

When Modifiers Are Required

Modifier -25: Applied when an E/M service is provided on the same day as a separately identifiable injection.

Modifier -59 or -76: Used in situations where the injection is performed on a separate site or repeated during the same encounter.
