Endothelial Cell Photography — CPB 0538 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0538 governing endothelial cell photography coverage, effective November 27, 2025. Billing teams using CPT 92286 or CPT 92287 need to verify diagnosis codes and surgical context before submitting claims.

Aetna Endothelial Cell Photography Coverage Criteria and Medical Necessity Requirements 2025

The Aetna endothelial cell photography coverage policy under CPB 0538 Aetna system covers two CPT codes: 92286 (special anterior segment photography with interpretation and report, with specular endothelial microscopy) and 92287 (with fluorescein angiography). Coverage depends entirely on whether your patient meets one of seven specific medical necessity criteria.

Aetna considers endothelial cell photography medically necessary when a member falls into any of these categories:

The real issue with this list is how surgical history drives coverage decisions. Four of the seven criteria involve prior or upcoming surgery. That means the clinical documentation needs to reflect surgical context, not just the current diagnosis.

The coverage policy does not list prior authorization requirements explicitly for CPT 92286 or 92287. That said, if your Aetna plan mix includes commercial or managed Medicaid products, check your specific contract terms. Prior auth requirements vary by product line even when the clinical policy is the same. If you're unsure, verify eligibility and benefits before scheduling the procedure.

Endothelial cell photography billing for Aetna reimbursement must be supported by documentation that maps directly to one of these seven criteria. A corneal diagnosis code alone is not enough. The clinical note needs to show why the test was ordered — and that reason must align with the policy.

Aetna Endothelial Cell Photography Exclusions and Non-Covered Indications

Aetna considers endothelial cell photography experimental, investigational, or unproven for any indication not listed in the seven criteria above. The policy language is direct: there is no proven clinical value for other indications. If the claim doesn't match one of the seven, it gets denied.

The more important exclusion — and this one catches billing teams off guard — is buried in the policy's limitation note. When endothelial cell photography is performed before cataract surgery, and the patient's only visual problem is cataracts, the procedure is considered an integral part of the pre-surgical comprehensive or brief/intermediate eye examination. That means it's bundled. It's not separately reimbursable.

This applies regardless of the cataract technique. Phaco-emulsification, traditional extracapsular, laser-assisted — it doesn't matter. If cataracts are the only diagnosis driving the surgery, you don't bill CPT 92286 or 92287 separately. You bill the exam.

The claim denial risk here is real. If your documentation shows a straightforward cataract case with no other corneal pathology or surgical history, and you still bill 92286, Aetna will deny it as included in the pre-surgical exam. The fix is clean documentation that clearly identifies a qualifying secondary condition.

There's one important carve-out from this bundling rule. Criterion four — prior intraocular surgery requiring cataract surgery — does qualify for separate coverage. The patient has cataracts, but the prior surgical history is the qualifying factor. Make sure your documentation reflects that distinction clearly.

CPT, HCPCS, and ICD-10 Codes for Endothelial Cell Photography Under CPB 0538

Covered CPT Codes (When Selection Criteria Are Met)

Key ICD-10-CM Diagnosis Codes

A quick note on the ICD-10 range H18.10–H18.239: The policy lists this as a range covering bullous keratopathy and other corneal edema. Make sure you're selecting the most specific code available for your patient's laterality and edema type. Unspecified codes increase audit risk.

The H18.51x codes map directly to endothelial corneal dystrophy — Fuchs' dystrophy falls here. The H18.59x codes cover other hereditary corneal dystrophies, including posterior polymorphous dystrophy. If you're billing for ICE syndrome, confirm the most appropriate ICD-10 code from the H18.59x range with your clinical team, as the ICD-10-CM specificity for ICE syndrome may require additional mapping review.
