HCPCS Level II code V2104 denotes the supply of a single-vision spherocylinder lens with spherical power from plano to ±4.00 diopters and cylindrical power from 2.12 to 4.00 diopters, billed per lens. The code is used by vision care providers, ophthalmology clinics, and optical dispensaries to document and bill for specific corrective lenses that address combined spherical and astigmatic refractive errors. Nationally, accurate use of V2104 matters for claims consistency, benefit design clarity, and proper capture of lens-specific utilization and costs.

This publication includes analysis for major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for spherocylinder single-vision lenses, typical sites of service, and the billing context for per-lens supply codes. The content outlines what to expect in benchmarking and coverage language across major payers, highlights common modifiers encountered in claims, and summarizes areas where policy clarifications or coding consistency can affect adjudication. Data not available in the input is noted where applicable.
