2025 CPT code 63620

Stereotactic radiosurgery for one spinal lesion using externally generated ionizing radiation.

Refer to the current CPT® guidelines for detailed coding instructions for stereotactic radiosurgery procedures.The same individual should not report stereotactic radiosurgery services with radiation treatment management codes (77427-77432).

Modifiers may apply depending on the circumstances of the procedure. Consult the CPT® guidelines for applicable modifiers.

Medical necessity is established through documentation supporting the diagnosis of a spinal lesion requiring treatment with stereotactic radiosurgery.The lesion must affect spinal neural tissue or abut the dura mater (for tumors), or be subdural (for AVMs). The chosen treatment method must be medically appropriate and consistent with current clinical guidelines.The treatment must be deemed medically necessary by the treating physician and should be supported by appropriate documentation to justify the clinical indications.

The neurosurgeon is responsible for performing the stereotactic radiosurgery procedure, including the planning, targeting, and delivery of radiation to the spinal lesion.The radiation oncologist handles the treatment planning, dosimetry, and management aspects of the radiation therapy.

IMPORTANT Code 63621 is used for each additional lesion treated after the first in the same course of treatment. Codes 77261-77790 from the Radiation Oncology section are reported by the radiation oncologist for planning, dosimetry, treatment delivery, and management.Do not report 63620, 63621 with 61781-61783 or 77427-77432.

In simple words: This medical code describes a procedure where doctors use special radiation to target and destroy a single problem area in the spine without surgery.Doctors use precise imaging to pinpoint the problem, then use radiation to treat it. This is done without cutting into the spine.

This CPT code, 63620, reports stereotactic radiosurgery for a single spinal lesion.The procedure involves using externally generated ionizing radiation (particle beam, gamma ray, or linear accelerator) to destroy a targeted area within the spine.Pre-operative imaging (CT or MRI) is used to define the target, which is then precisely targeted using a stereotactic system. The procedure is non-invasive, eliminating the need for surgical incision.Computer-assisted planning is included in this code.This code should not be reported more than once per course of treatment for a single lesion, even if multiple treatment sessions (up to five) are necessary.Additional lesions treated within the same course of treatment are reported using code 63621.

Example 1: A patient presents with a small, localized spinal tumor abutting the dura mater. Stereotactic radiosurgery (63620) is chosen as the treatment modality to precisely target and destroy the tumor without invasive surgery. , A patient with two separate spinal lesions is treated with stereotactic radiosurgery. Code 63620 is reported for the first lesion, and code 63621 is reported for the second lesion., A patient diagnosed with a spinal arteriovenous malformation (AVM) located subdurally is treated with stereotactic radiosurgery using the 63620 code. The radiation oncologist reports the appropriate codes for treatment planning and delivery.

* Detailed patient history and clinical presentation.* Pre-operative imaging (CT or MRI) demonstrating the lesion.* Documentation of lesion location, size, and proximity to critical structures.* Treatment plan outlining the radiation parameters (dose, fractionation).* Post-operative imaging (if obtained) to assess the treatment response.* Operative report detailing the procedure, including confirmation of the target and radiation delivery method.
