CPT® Code 68520

The procedure described by CPT® Code 68520 refers to the excision of the lacrimal sac, commonly known as dacryocystectomy. This surgical intervention is performed to address issues related to the lacrimal system, which is responsible for tear drainage. The lacrimal sac is a key component of this system, located at the inner corner of the eye, and is connected to the nasolacrimal duct that drains tears into the nasal cavity. During the procedure, the area surrounding the eye is first cleansed to minimize the risk of infection. A local anesthetic is then administered subcutaneously around the lacrimal sac to ensure the patient remains comfortable and pain-free throughout the surgery. An incision is made over the inner aspect of the lower eyelid, allowing the surgeon to access the lacrimal sac, nasolacrimal duct, and canaliculi, which are small channels that carry tears from the eye to the lacrimal sac. The excision of the lacrimal sac involves carefully removing it from its surrounding tissues. Following the excision, the proximal end of the nasolacrimal duct is cauterized to prevent bleeding and to promote healing. The canaliculi are also probed to assess their patency; if either the superior or inferior canaliculus is found to be open, they are cauterized as well. In cases where a fistula, or abnormal connection, is present, it is excised during the procedure. Finally, the surgical wound is closed, and a dressing is applied to protect the area as it heals.
