TL;DR: Aetna, a CVS Health company, modified CPB 0130 governing computerized corneal topography coverage, effective September 26, 2025. Here's what billing teams need to do.
CPB 0130 Aetna system defines eight covered indications for CPT 92025 — computerized corneal topography, unilateral or bilateral. If your practice bills this code for Aetna members, review your documentation requirements and charge capture now. The policy is active, and denials for missing medical necessity criteria are avoidable.

Aetna Computerized Corneal Topography Coverage Criteria and Medical Necessity Requirements 2025
Aetna's corneal topography coverage policy covers CPT 92025 — computerized corneal topography, unilateral or bilateral, with interpretation and report — when the patient meets at least one of eight defined conditions. If the diagnosis doesn't map to one of these, the claim won't survive a medical necessity review.
Here are the eight covered indications:
| # | Covered Indication |
|---|---|
| 1 | Central corneal ulcer |
| 2 | Corneal dystrophy, bullous keratopathy, or complications of a transplanted cornea |
| 3 | Diagnosing or monitoring disease progression in keratoconus or Terrien's marginal degeneration |
| 4 | Difficult fitting of contact lens (cross-reference CPB 0126) |
| 5 | Evaluating corneal ectasia |
| 6 | Post-traumatic corneal scarring |
| 7 | Pre- and post-penetrating keratoplasty, or post kerato-refractive surgery for irregular astigmatism |
| 8 | Pterygium or pseudo pterygium |
The real issue here is frequency documentation. Aetna's policy states that one test per eye is generally sufficient for contact lens fitting. If your provider orders a second test, the chart must show a documented reason — a change in the patient's condition from the prior exam. Don't bill a repeat CPT 92025 for contact lens fitting without that note in the record.
For keratoconus and Terrien's marginal degeneration, repeat testing to monitor disease progression is expected over time. That's the one indication where serial testing is explicitly supported. Make sure your ICD-10 coding reflects that diagnosis clearly — not just a generic corneal irregularity code — or you're inviting a claim denial.
Corneal topography billing tied to post-kerato-refractive surgery for irregular astigmatism falls under CPB 0023 (Corneal Remodeling) for the underlying procedure's medical necessity criteria. If your prior authorization workflow doesn't already link these two policies, it should. Check whether prior auth is required for the surgical procedure before billing topography as part of the pre-op workup.
Aetna does not publish a specific prior authorization requirement for CPT 92025 within CPB 0130 itself. That said, prior auth requirements can vary by plan and market. Before assuming no auth is needed, verify at the plan level — especially for high-volume topography practices.
Aetna Computerized Corneal Topography Exclusions and Non-Covered Indications
CPB 0130 does not list explicit "not covered" or experimental designations for corneal topography. Coverage is framed as medically necessary when criteria are met — which means anything outside the eight listed indications is implicitly not covered.
Routine refractive evaluation doesn't appear on the covered list. Neither does pre-op screening for LASIK in patients with no documented corneal pathology. If your ophthalmology or optometry practice performs topography as part of a standard refractive workup, those claims won't meet medical necessity under this coverage policy.
The real exposure here is contact lens fitting for simple myopia or astigmatism without a documented difficult fitting situation. "Difficult fitting" is a defined indication, but it requires documentation that supports that characterization — not just a notation that topography was performed. Vague chart language creates denial risk. Audit those records before claims go out.
Coverage Indications at a Glance
| Indication | Status | Relevant Code(s) | Notes |
|---|---|---|---|
| Central corneal ulcer | Covered | CPT 92025 | Requires supporting ICD-10 diagnosis |
| Corneal dystrophy, bullous keratopathy, transplant complications | Covered | CPT 92025 | Confirm ICD-10 specificity |
| Keratoconus or Terrien's marginal degeneration (diagnosis or monitoring) | Covered | CPT 92025 | Serial testing supported; document progression |
| Difficult contact lens fitting | Covered | CPT 92025, 92071, 92310–92320 | One test per eye standard; repeat requires documented reason |
| Corneal ectasia | Covered | CPT 92025 | Evaluate for post-refractive ectasia specifically |
| Post-traumatic corneal scarring | Covered | CPT 92025 | Trauma history must be documented |
| Pre/post penetrating keratoplasty; post kerato-refractive surgery for irregular astigmatism | Covered | CPT 92025, 65710–65775 range | Cross-reference CPB 0023 medical necessity criteria |
| Pterygium or pseudo pterygium | Covered | CPT 92025 | Confirm active pterygium diagnosis in chart |
| Routine refractive evaluation (no corneal pathology) | Not Covered | — | Fails medical necessity criteria |
| LASIK pre-op screening without documented corneal pathology | Not Covered | — | Not an enumerated indication |
| Simple contact lens fitting (no difficult fitting documentation) | Not Covered | — | Must document why fitting is "difficult" |
Aetna Computerized Corneal Topography Billing Guidelines and Action Items 2025
This policy has been active since September 26, 2025. If your team hasn't already audited CPT 92025 claims against these eight indications, do it now. Here's what to do:
| # | Action Item |
|---|---|
| 1 | Audit your CPT 92025 charge capture. Pull every CPT 92025 claim billed to Aetna in the past 90 days. Confirm each one has an ICD-10 diagnosis that maps to one of the eight covered indications. If it doesn't, assess your denial exposure and correct going forward. |
| 2 | Tighten documentation for contact lens fitting claims. One topography test per eye is Aetna's default for fitting. If you've billed repeat testing, the chart must show a documented change in the member's condition. Add this to your pre-billing checklist now. |
| 3 | Flag keratoconus monitoring cases for serial billing support. This is your cleanest path to repeat testing reimbursement. Make sure your providers document progression at each visit — not just the diagnosis. "Monitoring keratoconus, no change" won't support the claim the same way a documented progression note will. |
| 4 | Cross-check post-surgical topography with CPB 0023. Any CPT 92025 billed as pre- or post-operative for penetrating keratoplasty (CPT codes 65710–65775 range) or post kerato-refractive surgery for irregular astigmatism ties to CPB 0023 criteria. Make sure the underlying procedure met medical necessity before billing topography as part of that episode. |
| 5 | Verify prior auth requirements at the plan level. CPB 0130 doesn't specify a prior authorization requirement, but individual Aetna plan contracts vary. Check the plan-level prior auth list — especially for Medicare Advantage or commercial HMO products. Don't assume you're clear. |
| 6 | Train your coders on the "difficult fitting" distinction. The covered indication is difficult fitting of contact lens — not fitting of contact lens. Your coder and your provider need to agree on what documentation supports that distinction. If you're not sure whether your current documentation meets the bar, talk to your compliance officer before the claim goes out. |
