CPT® Code 50250

Ablation, open, 1 or more renal mass lesion(s), cryosurgical, including intraoperative ultrasound guidance and monitoring, if performed

The procedure described by CPT® Code 50250 involves the open ablation of one or more renal mass lesions using cryosurgery. Cryosurgery is a technique that employs extreme cold to destroy abnormal tissue, in this case, lesions located in the kidney. The procedure is performed through a wide flank incision, which allows the surgeon to access the kidney directly. During the operation, intraoperative ultrasound guidance may be utilized to accurately locate and monitor the lesions being treated. This guidance is crucial for ensuring that the cryosurgical probes are correctly positioned within the lesions. The ablation process consists of a series of freeze-thaw cycles, where the lesions are frozen to create an ice ball that extends beyond the margins of the lesions, effectively destroying the targeted tissue. After the cryosurgical treatment, the surgeon will control any bleeding, place drains if necessary, and then close the incision around the drains to facilitate recovery. This procedure is typically indicated for patients with renal mass lesions that require intervention to prevent further complications or progression of disease.
