Summary & Overview
HCPCS V2118: Aniseikonic Lens, Single Vision
HCPCS Level II code V2118 denotes an aniseikonic single-vision spectacle lens designed to correct perceptual image-size disparity between the eyes. These specialty lenses are clinically important because they address binocular vision disorders that can cause diplopia, asthenopia, or impaired stereopsis, and they influence durable medical equipment and vision coverage decisions nationally. Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise national perspective on the clinical role of V2118, who typically provides and receives these lenses, and what to expect in terms of payer coverage patterns and administrative considerations. The publication summarizes benchmark topics such as coverage scope, prior authorization triggers, and typical sites for service delivery (optical/vision care and outpatient ophthalmology/optometry clinics). It also highlights policy contexts that affect access and reimbursement for specialty corrective lenses. Data not provided in the input — such as detailed payer-specific rates, ICD-10 linkage, and taxonomy mappings — are noted where applicable as unavailable.
Billing Code Overview
HCPCS Level II code V2118 describes an aniseikonic lens, single vision. This item represents a single-vision spectacle lens manufactured to correct aniseikonia — a condition in which there is a significant difference in perceived image size between the two eyes. The service type is vision corrective lens provision, and the typical site of service is optical/vision care settings or outpatient ophthalmology/optometry clinics.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to an optometry or ophthalmology clinic with symptomatic aniseikonia after unilateral cataract extraction and intraocular lens implantation. The patient reports persistent image size disparity between the eyes, difficulty with depth perception, intermittent diplopia, and reading discomfort. The clinical workflow includes a comprehensive eye exam with refraction, binocular vision assessment (including Aniseikonia Inspector or space eikonometer testing), measurement of interocular spectacle magnification requirements, counseling on corrective options, and ordering of a custom single-vision aniseikonic spectacle lens coded as V2118. The optical laboratory receives a prescription specifying magnification or minification parameters, lens power, base curve, prism if needed, and specialty coatings. Follow-up visits assess symptom resolution, binocular fusion, and possible alterations in spectacle parameters or consideration of contact lens or surgical alternatives.
