CPT® Code 67904

The procedure described by CPT® Code 67904 involves the surgical repair of blepharoptosis, which refers to the drooping or sagging of the upper eyelid. This condition is typically caused by weakness in the levator palpebrae muscle, which is responsible for elevating the eyelid. The surgical approach utilized in this procedure is an external method, specifically through tarso levator resection or advancement. During the operation, a local anesthetic is administered to the upper eyelid to ensure patient comfort. The surgeon carefully measures the eyelid to determine the precise amount of tissue that needs to be resected or advanced to achieve the desired eyelid position. The external approach involves making an incision in the skin of the upper eyelid fold, allowing access to the underlying structures. This method is distinct from the internal approach, which is described under CPT® Code 67903. The external approach provides direct visibility and access to the anterior tarsal surface and levator aponeurosis, facilitating the necessary surgical adjustments to correct the ptosis effectively.
