Diagnosis examples listed in Applicable Codes

Unproven / Not Medically Necessary

Not covered when ANY of the following apply:

Children <1 year: Instrument-based ocular photoscreening is unproven and not medically necessary for children less than 1 year of age due to insufficient evidence of safety and/or efficacyage <1 year

From Coverage Rationale

Other individuals: Instrument-based ocular photoscreening is unproven and not medically necessary for all other individuals not meeting the proven indicationsother individuals

From Coverage Rationale

Retinal birefringence / Retinal polarization scanning

Retinal birefringence scan: Retinal birefringence/retinal polarization scanning is unproven and not medically necessary for detection of eye misalignment or strabismus due to insufficient evidence of safety and/or efficacyn/a

Despite description of the technique, policy classifies it as unproven

Coverage criteria — instrument-based pediatric vision screening

Covered when used according to professional recommendations and program best practices

Instrument-based screening recommended ages: Instrument-based screening (photoscreening/autorefraction) is useful for assessing amblyopia risk factors in children aged 1 to 5 years and can be used when optotype testing is not feasible; the AAO and AAPOS/AACO support use particularly for ages 1–5 or when children cannot participate in optotype testing.age 1-5 years

AAO and coauthors' guidance supports use; USPSTF finds moderate net benefit for ages 3-5 and insufficient evidence <3 years.

Program best practices: Best-practice vision screening for ages 36 to <72 months includes annual screening or at least once between ages 3 and 5 using monocular visual acuity (HOTV/LEA) or instrument-based testing (Retinomax or Suresight with VIP criteria); Plusoptix photoscreener is acceptable practice.36-72 months

NCCVEH recommended practices and VIP software/version guidance.

Instrument-based ocular photoscreening is classified as not medically necessary for children younger than 1 year of age because the policy states there is insufficient evidence of safety and/or efficacy in this age group. The policy also specifies that photoscreening is unproven and not medically necessary for individuals who do not meet the specified proven indications (i.e., outside the mass‑screening ages 1–5 years or the specified developmental‑delay exception).

The policy identifies certain devices and methods as having insufficient or mixed-quality evidence, with retinal birefringence/retinal polarization scanning highlighted specifically. Evidence summaries note that studies are often small, single‑center, or drawn from high‑risk populations, limiting generalizability. For example, Bosque et al. (2021) reported high sensitivity and specificity for one device in a prospective test‑validation study but used nonstandard calculations and had other limitations, while other studies and systematic reviews of photoscreeners show variable performance across devices and settings.

An operational change was made in this policy revision: the prior notation that CPT code 99177 was not on the State of North Carolina Medicaid Fee Schedule and therefore might not be covered by North Carolina Medicaid was removed. This deletion affects documentation of coding caveats but does not itself establish new coverage for the code.

Although retinal birefringence/retinal polarization scanning is described as a method that assesses central fixation and can detect strabismus with minimal cooperation, the policy explicitly classifies this approach as unproven and not medically necessary for detection of eye misalignment/strabismus due to insufficient evidence of safety and/or efficacy. The supporting studies include single‑center or high‑risk population evaluations with mixed results (e.g., Arnold 2020 and Bosque 2021), which the policy finds inadequate to support routine coverage for strabismus detection.

Overall, the policy concludes there is insufficient high‑quality evidence to broadly support retinal birefringence scanning. Existing studies report mixed accuracy: some report very high sensitivity and specificity in selected cohorts (Bosque et al.), while others (Arnold 2020) show lower sensitivity and specificity compared with alternative devices. Limitations cited include small sample sizes, single‑center designs, high‑risk study populations, and nonstandard analytic methods, which together limit the evidence base and generalizability.

Provider Actions and Billing Notes

Billing Rule

Provider Billing & Action Highlights

Actionable billing and provider guidance for vision screening and related codes. Reference federal, state, and contractual benefit requirements when determining coverage; in case of conflict, those requirements govern.

Applicable procedure codes include: 0469T (retinal polarization scan, bilateral), 99174 (instrument-based ocular screening with remote analysis and report, bilateral), and 99177 (instrument-based ocular screening with on-site analysis, bilateral).
Listing of a code in this policy is for reference only and does not guarantee reimbursement or imply coverage; benefit coverage is governed by federal, state, or contractual requirements and applicable laws.
Codes previously marked as not on the State of North Carolina Medicaid Fee Schedule have been updated: the prior notation removing CPT 99177 from the NC Medicaid Fee Schedule was deleted on 06/01/2026 — verify current state fee schedule applicability before billing.
Vision screening programs should record and report screening results to the family, primary care provider/medical home, and refer for comprehensive eye examination when indicated. Document referrals and follow-up for members who do not pass screening.
UnitedHealthcare reserves the right to modify policies; always check governing federal, state, and contractual documents and any state Medicaid fee schedules prior to submitting claims.

Background

Ocular photoscreening collects and analyzes images of the eyes using techniques such as photorefraction and assessment of the corneal light reflex/fundus reflection to identify amblyopia risk factors, strabismus, high refractive errors, anisometropia, and media opacities. It is a noninvasive, instrument‑based approach that requires limited patient cooperation and can be analyzed on‑site or remotely. These methods are intended to detect risk factors that warrant referral for a comprehensive eye examination rather than to provide a definitive diagnosis.

Definitions

Ocular photoscreening

DefinitionCollection and analysis of images of the eyes captured with a digital or film camera using photorefraction and corneal light reflex/fundus reflection

DefinitionMethod for detecting central fixation by measuring retinal birefringence (retinal polarization) to identify small- and large-angle strabismus
