The CPT® Code 66500 refers to a specific surgical procedure known as iridotomy by stab incision, which is classified as a separate procedure. This technique is primarily utilized in the management of various ocular conditions, including glaucoma, iris atrophy, papillary membrane adhesions, and aniridia. The procedure involves making a precise stab incision through the conjunctiva and into the lamellar sclera, allowing for the creation of a tunnel that facilitates access to the anterior chamber of the eye. The use of an operating microscope is essential for visualizing the intricate structures of the eye during the procedure, ensuring accuracy and safety. The stab incision technique is characterized by its careful dissection, which extends into the lamellar cornea and ultimately enters the anterior chamber horizontally. This method is designed to alleviate pressure and restore normal fluid dynamics within the eye, thereby addressing the underlying issues associated with the aforementioned conditions. It is important to note that this code does not include transfixion, which is a more complex procedure that involves additional steps to address specific complications such as iris bombe. Overall, CPT® Code 66500 represents a critical intervention in ophthalmic surgery aimed at improving patient outcomes in those suffering from significant eye disorders.

The procedure associated with CPT® Code 66500 is indicated for several specific ocular conditions that necessitate intervention to improve eye health and function. The following are the primary indications for performing a stab incision iridotomy:
The procedure for CPT® Code 66500 involves several critical steps that are performed with precision to ensure successful outcomes. The following outlines the procedural steps:
Post-procedure care following an iridotomy by stab incision is essential for ensuring proper healing and monitoring for complications. Patients are typically advised to follow up with their ophthalmologist to assess the success of the procedure and to check for any signs of infection or other issues. It is common for patients to experience some discomfort or transient changes in vision following the procedure, which should be monitored closely. Additionally, the healthcare provider may prescribe anti-inflammatory or antibiotic eye drops to aid in recovery and prevent infection. Patients should be instructed on signs of complications, such as increased pain, redness, or vision changes, and advised to seek immediate medical attention if these occur. Overall, proper post-procedure management is crucial for achieving optimal outcomes and maintaining eye health.

| SG | Ambulatory surgical center (asc) facility service | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 54 | Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number. | 55 | Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number. | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
