Summary & Overview
CPT 66940: Cataract Extraction with Capsular Retention
CPT code 66940 represents cataract surgery in which the surgeon removes the eye's natural lens while preserving the elastic capsular bag to allow implantation of an intraocular lens. This procedure is a common ophthalmic surgical service and has significant national importance due to its frequency, impact on vision restoration, and role in outpatient surgical care pathways.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service such as hospital outpatient departments and ambulatory surgical centers, and the operational billing considerations tied to this procedure.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with progressive blurring of vision and glare from a dense age-related cataract presents to the ophthalmology clinic for evaluation. After history, visual acuity testing, slit-lamp exam, and biometry for intraocular lens (IOL) power calculation, the surgeon schedules a planned extracapsular cataract extraction via phacoemulsification with intraocular lens implantation. On the day of surgery the patient undergoes preoperative verification, topical and/or local anesthesia, sterile field setup in an ambulatory surgery center or hospital outpatient department, and intraoperative monitoring by the surgical team. The surgeon performs removal of the natural crystalline lens while preserving the elastic capsular bag to allow placement of an intraocular lens, consistent with 66940. Postoperative care includes immediate recovery, short-term topical medications, and follow-up visits for visual rehabilitation and IOL positioning assessment.
