2025 CPT code 77372
(Active) Effective Date: N/A Revision Date: N/A Radiology Procedures - Radiation Oncology Treatment Radiology Feed
Stereotactic radiosurgery (SRS) using a linear accelerator for one session of treatment to cranial lesions.
Modifiers 59, 76, 77, 78, 79, may be applicable depending on the circumstances of the service rendered. Consult the most recent CPT guidelines and payer-specific guidelines before applying any modifiers.
Medical necessity for stereotactic radiosurgery is established based on the size, location, and characteristics of the lesion, as well as the patient's overall health and suitability for this treatment modality.Supporting documentation, including imaging and clinical evaluation, is essential for demonstrating medical necessity.
The clinical responsibility includes identifying the target area using stereotactic methods (CT or MRI images), placing the patient on the treatment table, aligning the robotic arm with the head, and operating the linear accelerator to deliver the prescribed radiation dose to the targeted brain lesion(s).
In simple words: This code describes a type of radiation treatment for brain tumors.A special machine precisely targets the tumor with radiation in one session, destroying the tumor while trying to protect healthy tissue.
This CPT code represents the technical component of stereotactic radiosurgery (SRS) where a linear accelerator delivers a single-session treatment to one or more cranial lesions.The procedure utilizes a three-dimensional coordinate system to precisely target and destroy the lesions while minimizing damage to surrounding healthy tissue. The linear accelerator generates high-energy X-rays or electrons for the radiation beam.Treatment planning, including image acquisition (CT or MRI), target localization, and dosimetry, is included in other codes (e.g., 77432).
Example 1: A patient presents with a small, well-defined meningioma in the brain.Stereotactic radiosurgery is chosen as the treatment modality.Code 77372 would be used to report the technical component of the single-session linear accelerator-based treatment., A patient with multiple small brain metastases is treated with SRS using a linear accelerator.Code 77372 is reported once for the entire session, even though multiple lesions were treated.Code 77432 would also be reported for the radiation treatment management., A patient with a vestibular schwannoma undergoes SRS treatment using a linear accelerator in a single session.Code 77372 would be reported for the technical component of the procedure.
* Detailed treatment plan including target volume delineation and dose calculations.* Images (CT or MRI) used for treatment planning.* Documentation of the linear accelerator settings used.* Verification of patient positioning and target alignment.* Confirmation of treatment delivery.* Pathology reports if applicable.
** This code does not include the professional component (physician interpretation and report). Code 77432 is used to report radiation treatment management which includes the professional components such as treatment planning and overall case management.Always confirm the most up-to-date information with the payer before submitting claims.
