CPT 66762 Reimbursement & Benchmarks

CPT code 66762 denotes an ophthalmic laser procedure that passes a laser beam through the iris to change its configuration, widen the anterior chamber angle, and improve vision. This microsurgical laser intervention is used in clinical contexts where altering iris configuration can relieve angle crowding and improve outflow or visual function. Nationally, this code is relevant for ophthalmology surgical billing and for payers evaluating coverage and coding consistency for angle-modifying laser techniques.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical purpose of the procedure, common sites of service (ambulatory surgical centers and hospital outpatient departments), and the scope of payer engagement. The publication outlines common billing modifiers associated with this service (provided in source data), typical clinical context, and what to expect in payer interactions.

This summary serves clinicians, coding specialists, and policy analysts seeking a national-level overview of CPT code 66762, its clinical intent, and the payer landscape. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 66762 describes a laser procedure in which the provider passes a laser beam through the iris to alter its configuration, increasing the anterior chamber angle width and aiming to improve vision. This procedure is an ophthalmologic laser intervention targeting the iris and anterior chamber angle.

Service type: Ophthalmic laser surgical procedure
Typical site of service: Ambulatory surgical center or hospital outpatient department

Clinical Context

A typical patient is a 60-year-old with primary angle-closure glaucoma or narrow angles identified on gonioscopy who experiences intermittent eye pain, blurred vision, or elevated intraocular pressure despite medical therapy. The ophthalmologist schedules a laser peripheral iridotomy to create a full-thickness opening in the peripheral iris using a laser beam to improve aqueous outflow and widen the drainage angle. Pre-procedure workflow includes informed consent, topical anesthesia, pilocarpine or other miotic to appose iris to the lens per protocol, antiseptic preparation, placement of a laser contact lens, and intraoperative monitoring of intraocular pressure. Post-procedure workflow includes intraocular pressure measurement within 30–60 minutes, topical anti-inflammatory and ocular hypotensive medications as indicated, discharge instructions for urgent symptoms, and follow-up gonioscopy to confirm patency of the iridotomy and assess angle width.
