CPT Code Overview
CPT 37799 is designated as an unlisted procedure for vascular surgery. This code is used when a surgical intervention on the cardiovascular system is performed that does not have a specific CPT code assigned. Procedures billed under CPT 37799 typically involve arteries or veins and may address a range of vascular conditions. The service type is classified as Surgical Procedures on the Cardiovascular System – Other Artery and Vein Procedures.

This flexibility allows providers to report unique or uncommon vascular surgical procedures that fall outside standard coding definitions.
Clinical & Coding Specifications
Clinical Context
A patient presents with chronic venous insufficiency or varicose veins of the lower extremities, possibly accompanied by symptoms such as leg swelling, pain, or visible vein abnormalities. After evaluation by a vascular surgeon, it is determined that standard procedures (such as endovenous ablation or vein stripping) are not suitable due to unique anatomical or clinical factors. The surgeon performs a specialized vascular surgery procedure that does not have a specific CPT code, requiring the use of 37799 (Unlisted procedure, vascular surgery). The procedure may occur in an outpatient surgical center, hospital, or office setting, depending on the complexity and patient needs. Documentation must clearly describe the procedure performed and its medical necessity.
