HCPCS Level II code V2103 identifies a spherocylinder single-vision lens (per lens) for prescriptions ranging from plano to ±4.00 diopters sphere and 0.12 to 2.00 diopters cylinder. This code is used to document and bill for a common category of corrective ophthalmic lenses that address both spherical refractive error and astigmatism in a single-vision format. Nationally, V2103 matters because it standardizes reporting for a widely dispensed optical product across retail and clinical settings, supporting consistent benefits administration and claims processing for vision care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for V2103, typical sites of service, and what the code represents operationally. The publication also outlines common modifiers and service-line considerations where available, plus benchmarks and policy-relevant notes when present. Data not available in the input is clearly indicated where applicable. The content is intended for billing professionals, coders, and vision-care administrators seeking a national perspective on classification and practical billing context for single-vision spherocylinder lenses.
