Summary & Overview
HCPCS V2318: Aniseikonic Lens, Trifocal
HCPCS Level II code V2318 denotes an aniseikonic trifocal lens — a specialized ophthalmic device that combines image-size correction for aniseikonia with trifocal optics to address distance, intermediate, and near vision. Nationally, this code is relevant for vision specialists, optical dispensers, and payers managing coverage for advanced intraocular and spectacle lens technologies that address both binocular image-size disparity and presbyopia.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an explanation of the clinical context for use of aniseikonic trifocal lenses, the typical service setting, and what to expect in terms of coding designation. The publication outlines benchmarks and coverage considerations where available, clarifies common modifiers and billing practices (list provided separately), and highlights policy or reimbursement updates that commonly affect HCPCS Level II device codes.
This summary serves clinicians, billing professionals, and policy analysts seeking concise, actionable information about the purpose and administrative handling of V2318, its place in care pathways for complex refractive cases, and the payer landscape relevant to coverage and claims processing.
Billing Code Overview
HCPCS Level II code V2318 describes an aniseikonic lens, trifocal. This entry represents a specialized ophthalmic lens designed to correct aniseikonia (a perceived difference in image size between the two eyes) while providing trifocal optical correction for distance, intermediate, and near vision.
-
Service type: Provision and fitting of a specialty trifocal ophthalmic lens intended to address both aniseikonia and presbyopic or multifocal visual needs.
-
Typical site of service: Outpatient ophthalmology clinic, optical dispensary, or specialized vision care center where custom lens evaluation, measurement, and fitting are performed.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with unequal retinal image sizes and symptomatic spectacle-induced anisometropia is evaluated in an ophthalmology clinic. The patient reports difficulty with reading and intermittent diplopia when wearing bifocal spectacles. After refraction, binocular vision testing, and assessment of retinal correspondence, the ophthalmologist determines that an aniseikonic correction is indicated. A custom V2318 aniseikonic trifocal lens is ordered to address both image size disparity and presbyopic near needs. Typical workflow: preoperative consult and measurements (including spectacle lensometry, careful keratometry, pupillometry, and aniseikonia measurements), ordering and fabrication of the custom aniseikonic trifocal lens, dispensing appointment with verification of fit and visual outcome, and follow-up visits for adaptation and potential adjustments. Typical site of service is an ophthalmology clinic, optical dispensary, or ambulatory surgical center when combined with procedures; manufacturing and dispensing may involve optical labs and certified contact lens or spectacle labs. Patient scenario modifiers may include bilateral or unilateral services and professional vs technical components depending on provider involvement and dispensing arrangements.
