Official Description

Ligation (percutaneous) of vas deferens, unilateral or bilateral (separate procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 55450 refers to the procedure of percutaneous ligation of the vas deferens, which can be performed unilaterally or bilaterally. This procedure is classified as a separate procedure, indicating that it is distinct from other surgical interventions. The term "percutaneous" signifies that the procedure is performed through the skin, typically using minimally invasive techniques. The vas deferens is a crucial component of the male reproductive system, responsible for transporting sperm from the testicles to the urethra. Ligation of the vas deferens is often associated with sterilization procedures, as it effectively prevents sperm from being included in the ejaculate. The procedure can be accomplished using either a needle and diathermy wire or through a conventional vasectomy technique, which involves cutting the vas deferens and sealing the ends to prevent sperm passage. The approach chosen may depend on the surgeon's preference and the specific circumstances of the patient. Overall, this procedure is designed to provide a permanent method of contraception by interrupting the normal pathway of sperm delivery.
