TL;DR: Aetna, a CVS Health company, modified CPB 0023 governing corneal remodeling coverage, effective March 17, 2026. Here's what billing teams need to know before claims start hitting the wall.
Aetna's corneal remodeling coverage policy under CPB 0023 has been updated as of March 17, 2026. This policy governs procedures used to reshape the cornea — including orthokeratology, laser-based refractive procedures, and related interventions — and defines what Aetna considers medically necessary versus experimental. The published policy data for this update does not list specific CPT or HCPCS codes, so your team will need to pull the full CPB 0023 document directly from Aetna's clinical policy bulletin library to confirm code-level applicability.

Aetna Corneal Remodeling Coverage Criteria and Medical Necessity Requirements 2026
CPB 0023 in the Aetna system is the clinical policy bulletin that controls how Aetna evaluates corneal remodeling billing. Corneal remodeling is a broad category. It covers orthokeratology (rigid contact lenses worn overnight to reshape the cornea), laser refractive procedures like LASIK and PRK, and certain conductive keratoplasty or thermal keratoplasty approaches.
The core tension in Aetna's corneal remodeling coverage policy — and in most payer policies covering this category — is medical necessity versus elective intent. Most corneal remodeling procedures are performed for refractive correction. Aetna, like most commercial payers, treats refractive correction as a vision benefit exclusion under medical plans.
That said, medical necessity arguments do exist for specific diagnoses. Keratoconus is the clearest example. Patients with progressive keratoconus who can no longer achieve functional vision with standard spectacles or soft lenses have a stronger medical necessity basis than patients seeking myopia correction. If CPB 0023 has tightened or expanded those criteria with this March 17, 2026 update, that's where your claims exposure lives.
Because the published update data does not include the full policy text or specific criteria language, pull the complete CPB 0023 document from Aetna's clinical policy bulletin portal before submitting any corneal remodeling claims dated on or after the effective date. Don't rely on the prior version. Aetna's policy bulletins carry a revision date — confirm you're reading the March 2026 version.
Prior authorization is a real factor here. Aetna routinely requires prior authorization for non-routine ophthalmic procedures that cross into medical territory. If your practice has been submitting corneal remodeling claims without prior auth and getting paid, a policy modification is exactly the moment that changes. Verify your prior authorization requirements against the updated CPB 0023 before the next claim goes out.
Aetna Corneal Remodeling Exclusions and Non-Covered Indications
Reimbursement for corneal remodeling under Aetna's medical benefit — as opposed to any vision rider — has always been narrow. The core exclusions in policies like CPB 0023 typically include:
Elective refractive correction. LASIK, PRK, and orthokeratology for myopia, hyperopia, or astigmatism in otherwise healthy eyes are not covered as medical benefits. This is not new. But if the March 17, 2026 modification sharpened the language around what counts as "elective," your medical necessity documentation needs to be tighter.
Investigational or experimental procedures. Corneal remodeling includes some techniques that remain in clinical development. Corneal cross-linking for progressive keratoconus, for example, has moved from experimental to covered under many payer policies over the past several years. If CPB 0023 has reclassified any technique in either direction, that's a direct claim denial risk.
Procedures without adequate peer-reviewed evidence. Aetna's clinical policy bulletins follow an evidence-based structure. Techniques that lack randomized controlled trial support typically land in the "not medically necessary" or "experimental" bucket. This affects newer corneal remodeling approaches more than established ones.
Because the full updated policy text isn't available in this data set, your compliance officer should review CPB 0023 directly and compare it line by line against the prior version. A policy modification can shift a single word — "medically necessary" to "medically required," or "progressive keratoconus" to "documented progressive keratoconus with visual acuity worse than 20/40" — and that word shift changes your claim outcome.
Coverage Indications at a Glance
The published policy update data does not include indication-level criteria or code-level coverage designations. The table below reflects what's typically at play in corneal remodeling policies of this type — but treat this as a starting framework, not a substitute for reading the actual CPB 0023 document.
| Indication | Typical Status | Notes |
|---|---|---|
| Keratoconus with documented progression | Potentially covered (medical necessity criteria apply) | Prior auth typically required; visual acuity thresholds vary |
| Elective myopia/hyperopia/astigmatism correction | Not covered under medical benefit | May be a vision rider benefit; not medical plan |
| Corneal cross-linking for keratoconus | Coverage status varies by plan year | Many plans now cover; confirm CPB 0023 March 2026 language |
| Orthokeratology for myopia control in pediatric patients | Typically not covered | Considered elective by most commercial payers |
| Post-surgical corneal remodeling (e.g., post-RK complications) | Case-by-case; medical necessity documentation required | Consult updated CPB 0023 criteria |
| Investigational refractive techniques | Not covered | Classified as experimental pending peer-reviewed evidence |

Aetna Corneal Remodeling Billing Guidelines and Action Items 2026
Here's what to do before March 17, 2026 and immediately after.
| # | Action Item |
|---|---|
| 1 | Pull the full CPB 0023 document now. Go to Aetna's clinical policy bulletin library and download the version with the March 17, 2026 effective date. Read it against the prior version. If you don't have access to the prior version, your Aetna provider relations contact can get it for you. Don't guess at what changed. |
| 2 | Audit your prior authorization workflow for corneal remodeling billing. If Aetna added or modified prior auth requirements in this update, any claim submitted after March 17, 2026 without the required auth will deny. Check your practice management system's prior auth rules for corneal remodeling procedures and update them to reflect CPB 0023 as modified. |
| 3 | Review your medical necessity documentation templates. If your team uses templated clinical notes or superbills for corneal remodeling, the updated coverage policy may require additional diagnosis specificity — visual acuity measurements, documented progression rates, failed conservative treatment. Update your templates before the effective date. |
| 4 | Check claim denial patterns from the past 90 days. If Aetna has been soft-denying corneal remodeling claims recently, this policy modification may be the formal codification of a coverage position they've already been applying. Pull your denial reports and look for patterns in adjustment codes. EOB language around "not medically necessary" or "experimental" is your signal. |
| 5 | Talk to your compliance officer if you're unsure how this applies to your procedure mix. Corneal remodeling billing guidelines sit at the intersection of medical and vision benefits, and the line between covered and non-covered is often diagnosis-specific. If your practice bills a mix of keratoconus-related procedures and elective refractive work, the risk exposure is real. Don't file after March 17, 2026 on the old criteria without a compliance review. |
| 6 | Confirm whether this affects any pending authorizations. If you have prior authorizations approved under the old CPB 0023 criteria, verify whether Aetna honors those auths through their service dates or whether the March 17 modification resets the clock. Call Aetna provider services to confirm — don't assume grandfathering. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Corneal Remodeling Under CPB 0023
The published policy data for this update does not include specific CPT, HCPCS, or ICD-10 codes. Do not rely on externally assumed codes for billing decisions.
To get the authoritative code list for CPB 0023 as modified effective March 17, 2026, do the following:
- Download the full CPB 0023 document from Aetna's clinical policy bulletin library
- Look for the "Applicable Codes" section, which Aetna includes in most CPBs
- Cross-reference those codes against your charge capture for corneal remodeling procedures
- If the updated CPB 0023 adds or removes codes from the covered or non-covered lists, update your charge capture and claim scrubber rules before the effective date
Fabricating or assuming codes in a live billing environment is how claim denials happen at scale. The codes in this policy will be specific — and the difference between one CPT code and the next in ophthalmic surgery can be the difference between covered and non-covered under Aetna's billing guidelines.
