HCPCS Level II code V2106 identifies a single-vision spherocylindrical eyeglass lens for patients requiring substantial astigmatic correction (cylinder over 6.00 diopters) with spherical power from plano to ±4.00 diopters. This code is used in billing for the fabrication and dispensation of corrective lenses tailored to high-cylinder prescriptions and informs coverage, pricing, and benefit design across payers. Nationally, V2106 matters because it captures higher-complexity lens fabrication that can affect benefit limits, retail optical allowances, and prior-authorization requirements for vision benefits.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical and service context for V2106, what sites typically bill the code, and which payers commonly appear in coverage policies. The publication outlines expected benchmarks and comparisons where available, summarizes relevant policy considerations for vision benefits (such as lens allowances and prior-authorization triggers), and provides clinical context on when a high-cylinder single-vision lens is indicated. Data not available in the input is noted where applicable. The content is intended for national audiences including billing managers, compliance officers, optical vendors, and clinician offices seeking a clear reference on V2106.
