Summary & Overview
CPT 66983: Cataract Extraction with Intraocular Lens Implantation
CPT code 66983 represents surgical removal of the cataractous lens and capsule as one unit followed by insertion of an intraocular lens prosthesis. This procedure is a core intervention in ophthalmology to restore vision impaired by cataract and is widely performed across ambulatory surgical centers, hospital outpatient departments, and specialized eye surgery centers. Nationally, cataract surgery is one of the most frequently billed surgical services, making accurate coding and coverage determinations for 66983 important for clinical workflow and payer reimbursement.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for 66983, including common sites of service and service type, plus an overview of coverage considerations and benchmarking topics relevant to national payers. The publication covers typical billing patterns, common modifiers and claims considerations (listed elsewhere), and points of interest for policy and utilization management. Data not available in the input is noted where applicable. The goal is to provide clinicians, billing specialists, and policy analysts with a clear, national-level summary of what CPT code 66983 denotes and why it matters in surgical ophthalmology and payer interactions.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient presents with progressive, painless decline in visual acuity over months, with glare and difficulty reading consistent with a senile cataract affecting activities of daily living. Preoperative evaluation by the ophthalmologist includes slit-lamp exam confirming lens opacity, manifest refraction, biometry (axial length and keratometry), corneal topography as indicated, and systemic assessment for anesthesia risk. The patient receives informed consent for phacoemulsification with intraocular lens implantation. On the day of surgery the patient receives topical or local anesthesia in an ambulatory surgical center or hospital outpatient department. The surgeon performs 66983 — intracapsular cataract extraction with insertion of an intraocular lens prosthesis — removing the lens and capsule as a single piece and implanting a prosthetic lens. Postoperative workflow includes immediate recovery monitoring, topical antibiotic and anti-inflammatory prescriptions, and follow-up visits at postoperative day one, one week, and one month for visual and wound assessment. Documentation includes operative note with laterality, anesthesia type, implant power and model, intraoperative complications, and postoperative instructions.
