The procedure described by CPT® Code 66630 refers to an iridectomy, specifically a sector iridectomy performed with a corneoscleral or corneal section, which is classified as a separate procedure. This surgical intervention involves the removal of a portion of the iris, which is the colored part of the eye, to effectively treat glaucoma. The primary goal of this procedure is to facilitate the drainage of aqueous humor, the fluid within the eye, from the anterior chamber to the posterior chamber. By doing so, it helps to lower intraocular pressure (IOP), which is crucial in managing glaucoma, particularly in cases of angle-closure glaucoma where other treatments, such as laser iridotomy, have not succeeded in achieving adequate pressure reduction. During the procedure, a topical anesthetic is applied to ensure patient comfort. The surgeon makes an incision in the cornea, typically at the limbus, the junction where the cornea meets the sclera. In this specific procedure, a larger, wedge-shaped section of the iris is excised compared to other related procedures, such as CPT® Code 66625, which involves a smaller full-thickness section. Importantly, the corneal incision made during the procedure is generally left open, as it is expected to close and heal naturally without the need for sutures. Post-operative care may include the application of antibiotic eye drops, and the use of a contact lens bandage or an eye patch to protect the eye during the healing process.

The iridectomy procedure described by CPT® Code 66630 is indicated for specific conditions related to glaucoma. The following are the primary indications for performing this procedure:
The procedure for CPT® Code 66630 involves several critical steps that ensure the successful removal of a sector of the iris to treat glaucoma. The following outlines the procedural steps:
After the iridectomy procedure, patients can expect a recovery period during which the eye will heal. It is important to monitor for any signs of complications, such as increased pain, redness, or changes in vision. Patients are typically advised to follow up with their ophthalmologist to assess the healing process and ensure that intraocular pressure remains within a safe range. The use of antibiotic drops is essential to prevent infection, and the protective contact lens or eye patch may be worn for a specified duration as directed by the healthcare provider. Overall, the recovery process is generally straightforward, with most patients experiencing gradual improvement in their symptoms as the eye heals.

| 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). | 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.) | 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) | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
