CPT code 76511 denotes quantitative A–scan ultrasound imaging of intraocular and orbital structures, a diagnostic ophthalmic procedure that provides precise axial measurements and acoustic information used in evaluation and management of ocular conditions. Nationally, this code matters for clinical workflows in ophthalmology and for payers because it supports preoperative assessments, biometric measurements for intraocular lens calculations, and diagnosis of intraocular masses or posterior segment abnormalities.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 76511 represents, common sites of service, and how this service fits into ophthalmic diagnostic pathways. The publication outlines benchmark considerations, coding and billing context, and relevant clinical applications tied to ocular measurement and orbital evaluation. Where payer-specific coverage details or utilization benchmarks are not provided in the input, the text indicates that data is not available in the input.

This summary orients clinical coders, billing professionals, and policy analysts to the primary purpose of CPT code 76511, its typical use settings, and the national payers relevant to reimbursement and policy discussions.
