HCPCS Level II code V2100 denotes a single-vision spherical lens provided per lens, with a power range from plano to ±4.00 diopters. This supply code is used when a standard corrective lens meeting those spherical specifications is furnished to a patient and is relevant across vision benefit programs and medical plans that cover corrective lenses. The code matters nationally because it standardizes reporting for a common optical supply used in routine refractive correction and influences coverage, prior authorization, and billing practices across major payers.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage patterns, typical sites of service, and clinical context for when a single-vision spherical lens in this power range is appropriate. The publication provides benchmarks for utilization and reimbursement structures where available, summarizes relevant policy considerations affecting coverage of optical supplies, and explains the clinical scenario tied to this code. Data limitations or unavailable items from the input are noted where applicable. The content is intended for a national audience of billing managers, policy analysts, and clinical administrators seeking concise guidance on coding and administrative context for HCPCS Level II code V2100.
