CPT® Code 68770

The procedure described by CPT® Code 68770 refers to the closure of a lacrimal fistula, which is classified as a separate procedure. A lacrimal fistula is an abnormal connection or passageway that forms between the lacrimal system and the skin, allowing tears or other fluids to drain externally. These fistulas can be either congenital, meaning they are present at birth, or acquired, which may occur due to trauma or disease processes such as infections. Congenital fistulas can be categorized into open and closed types. Open fistulous tracts are characterized by a visible small hole located inferior to the medial canthus, where tears or other fluids can leak onto the skin. In contrast, closed fistulous tracts terminate in a blind sac and do not exhibit any drainage. The closure of a lacrimal fistula typically involves the administration of a local anesthetic to ensure patient comfort during the procedure. Following anesthesia, the fistulous tract is carefully inspected, and the closure is achieved through techniques such as electrocautery or laser surgery, among other methods. This procedure aims to restore normal drainage of tears and prevent any further complications associated with the fistula.
