Corneal Topography | UHC Coverage Update

TL;DR: UnitedHealthcare modified its corneal topography coverage policy, effective October 1, 2025. Here's what billing teams need to do before that date.

UnitedHealthcare updated its Medicare Advantage medical policy for corneal topography, covering CPT 92025. The policy spells out exactly which diagnoses support medical necessity—and which ones will get your claim denied. If your practice bills 92025 for ophthalmology patients on Medicare Advantage, this coverage policy change requires action before October 1, 2025.

UnitedHealthcare Corneal Topography Coverage Criteria and Medical Necessity Requirements 2025

The UnitedHealthcare corneal topography coverage policy is built around one core question: does the patient have a documented corneal condition from the approved list? If the answer is yes and it's in your chart notes, CPT 92025 is coverable. If the answer is no—or if the documentation doesn't support it—expect a claim denial.

UnitedHealthcare considers CPT 92025 (computerized corneal topography, unilateral or bilateral, with interpretation and report) reasonable and necessary for the following conditions:

That's a substantive list, and it maps to a large ICD-10 code set—91 diagnosis codes in total. The breadth of covered diagnoses is actually useful here. Many of these conditions are chronic, so your ophthalmology patients with keratoconus (H18.601–H18.623), corneal ectasia (H18.711–H18.713), or corneal dystrophies (H18.511–H18.593) may qualify repeatedly across their treatment course.

The cataract surgery rule is the one most likely to trip your billing team up. Corneal topography is only covered for pre-operative cataract patients when documentation explicitly supports irregular astigmatism. A standard pre-op cataract workup does not automatically justify 92025. The chart note must state irregular astigmatism—not just astigmatism, not just "irregular cornea," but specifically irregular astigmatism. If your surgeons aren't documenting it that precisely, you'll lose those claims.

There is no NCD for corneal topography. That means local coverage determinations (LCDs) and local coverage articles (LCAs) from your Medicare Administrative Contractor (MAC) govern where they exist. UnitedHealthcare Medicare Advantage plans are required to comply with applicable LCDs and LCAs. If you're billing in a state or territory where an LCD applies, you need to verify that your documentation meets both the LCD requirements and this UHC policy. These aren't always identical. Talk to your compliance officer if you're unsure which MAC LCD applies to your region before the October 1, 2025 effective date.

This policy does not list prior authorization requirements for CPT 92025 directly. That said, UnitedHealthcare Medicare Advantage plans can impose prior auth requirements at the plan level. Confirm prior authorization status for 92025 with each specific plan before assuming none is required.

UnitedHealthcare Corneal Topography Exclusions and Non-Covered Indications

UnitedHealthcare is explicit about what doesn't qualify. These exclusions are clean and worth knowing cold before you submit.

Screening is not covered. If there are no associated signs, symptoms, illness, or injury from the approved list, the service is non-covered. A patient who comes in for a routine eye exam and gets corneal topography "just to check" will not be reimbursed under this policy. That's not a documentation issue—it's a coverage issue. No amount of good notes fixes a non-covered indication.

Pre- or post-operative topography related to Medicare non-covered procedures is not covered. The policy calls out radial keratotomy specifically. If a patient is getting or has had radial keratotomy—a procedure Medicare does not cover—corneal topography tied to that procedure is also non-covered. This comes up more than you'd think with older patients who had RK done decades ago and now present with post-surgical irregular astigmatism. Document carefully. The topography needs to be clinically justified by a separate covered indication, not the RK history itself.

These are the steps your billing team should complete before October 1, 2025.

If your practice sees a high volume of cataract surgery patients or has significant keratoconus/dystrophy caseload, this policy change has real revenue exposure. Talk to your billing consultant or compliance officer before the effective date if you're uncertain about your ICD-10 pairings.
