Coverage Summary

This state-specific UnitedHealthcare medical policy for Idaho (Policy Number CS378ID.A) addresses ocular photoscreening and related technologies; it became effective June 1, 2025. The policy defines a mixed coverage stance: instrument-based ocular photoscreening is considered medically necessary in specified situations but other uses and certain technologies (e.g., retinal birefringence/polarization scanning) are considered unproven/not medically necessary under this policy.

Medical-Necessity Criteria

Medically Necessary (Proven) Uses

Instrument-based ocular photoscreening is proven and medically necessary when ANY of the following are met:

ANY of the following

As a mass screening instrument for children 1-5 years of age (ends on 6th birthday).
In individuals 6 years of age and older who are developmentally delayed and are unable or unwilling to cooperate with routine visual acuity screening.

Not Medically Necessary / Unproven

Instrument-based ocular photoscreening or specific technologies are unproven and not medically necessary when ALL of the following apply:

ALL of the following

Instrument-based ocular photoscreening for all other individuals not described as medically necessary, including children less than 1 year of age, due to insufficient evidence of safety and/or efficacy.
Retinal birefringence scanning/retinal polarization scanning for detection of eye misalignment or strabismus due to insufficient evidence of safety and/or efficacy.

Policy applies to Idaho, including Idaho Medicaid Plus; providers must follow applicable federal, state, or contractual benefit requirements.

Background and Definitions

Ocular photoscreening involves capturing and analyzing images of the eyes to detect amblyopia risk factors such as strabismus, high refractive errors, anisometropia, and media opacities; it is based on photorefraction and assessment of corneal light reflex and fundus reflections to infer fixation and misalignment. The policy notes that retinal polarization/birefringence scanning (RBS) evaluates central fixation and can detect strabismus with minimal patient cooperation, but current evidence is insufficient to support routine coverage of RBS for detection of eye misalignment or strabismus.

Term	Definition
Instrument-based ocular photoscreening	Method for detection of visual impairments using images of the eyes captured with a digital or film camera, analyzed to identify amblyopia risk factors.
Retinal birefringence scanning / retinal polarization scanning	Technique to detect central fixation and potential strabismus by measuring birefringent properties of the retina; considered investigational in this policy.

Source	Summary
USPSTF 2017	Moderate net benefit for vision screening in children aged 3-5 years; benefits for children younger than 3 years are uncertain.
AAO 2022	Recommends instrument-based screening useful for children 1-5 years and for developmentally delayed older children who cannot cooperate with optotype testing.
