CPT 77373 refers to stereotactic body radiation therapy (SBRT), a highly precise form of radiation treatment designed to target and destroy tumors located in various parts of the body, excluding the brain and spinal cord.

This code represents the technical component of a procedure in which the provider performs stereotactic body radiation therapy. The therapy uses a three–dimensional coordinate system to locate small targets or lesions inside the body, other than the brain and spinal cord, and destroys them with precision using externally generated ionized ...

This code is specifically for the treatment phase where high doses of radiation are precisely delivered to a targeted area within the body, typically for treating tumors in areas such as the lungs, liver, or spine.

For SRS and SBRT with inverse planning, it is appropriate to bill CPT codes 77301 (both simulation and planning) and either 77371/77372 (single fraction delivery) or 77373 (multifaction delivery). Please see the chart below for a summary.
