Summary & Overview
CPT 66991: Cataract Removal with Intraocular Lens Implantation
CPT code 66991 is a critical billing code for extracapsular cataract removal with intraocular lens implantation, a procedure widely performed in ophthalmology to address vision impairment caused by cataracts. This code covers a one-stage surgical intervention using manual or mechanical techniques, such as irrigation and aspiration or phacoemulsification, and is typically conducted in ambulatory surgical centers or office-based surgical suites. The procedure is essential for improving patient outcomes and quality of life, making it a focal point in both clinical practice and medical billing.
Major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare, recognize and reimburse for this procedure, underscoring its importance in the healthcare system. Readers will gain insight into payer coverage, clinical benchmarks, and policy updates relevant to this CPT code. The publication also provides context on related codes, common modifiers, and associated diagnoses, offering a comprehensive overview for stakeholders in ophthalmology and medical billing. This summary serves as a resource for understanding the national landscape of cataract surgery billing and reimbursement.
CPT Code Overview
CPT code 66991 describes extracapsular cataract removal with insertion of intraocular lens prosthesis as a one-stage procedure, performed using manual or mechanical techniques such as irrigation and aspiration or phacoemulsification. This service falls under ophthalmology (anterior segment surgery) and is commonly provided in an ambulatory surgical center or an office-based surgical suite (e.g., POS 24 or 11). The procedure is a cornerstone in the treatment of cataracts, restoring vision by replacing the clouded natural lens with an artificial intraocular lens.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting with decreased vision due to a cataract, most commonly age-related. The patient is evaluated by an ophthalmologist, who determines that extracapsular cataract removal with intraocular lens implantation is indicated. The procedure is performed in an ambulatory surgical center or office-based surgical suite. The workflow includes preoperative assessment, anesthesia, manual or mechanical removal of the cataract (such as phacoemulsification), insertion of an intraocular lens prosthesis, and postoperative care. The procedure is usually performed on one eye at a time, but may be bilateral in certain cases.
