CPT code 66987 denotes complex intraocular lens implantation after extracapsular cataract extraction when additional techniques or devices are needed, and it includes endoscopic cyclophotocoagulation to address or prevent glaucoma. This code captures higher-complexity anterior segment surgical care that frequently occurs in hospital outpatient departments and ambulatory surgery centers and has implications for surgical coding, coverage, and payment policies across payers nationally. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical services bundled under the code, typical sites of service, common billing modifiers, and how payers approach authorization and coverage considerations. The publication also outlines benchmarking elements and policy updates relevant to surgeons and billing teams, and provides clinical context for when complex techniques such as iris expansion, suture-supported lenses, or early developmental procedures are used alongside cyclophotocoagulation.
