Aetna modified CPB 0321 for behavioral vision therapy and vision restoration therapy, effective September 26, 2025. Here's what billing teams need to know.
Aetna, a CVS Health company, updated Clinical Policy Bulletin 0321, which governs behavioral vision therapy and vision restoration therapy coverage. The policy directly affects CPT 92065 (orthoptic and pleoptic training) and CPT 97533 (sensory integrative techniques). If your practice bills either code to Aetna, review your documentation workflows and charge capture before September 26, 2025.

Aetna Behavioral Vision Therapy Coverage Criteria and Medical Necessity Requirements 2025
The Aetna behavioral vision therapy coverage policy under CPB 0321 is blunt about where it draws lines. Aetna treats behavioral vision therapy — the kind marketed for learning disabilities, dyslexia, and reading disorders — as experimental and investigational for those indications. That position has not changed, and this modification keeps it in place.
The real story with CPB 0321 is the ICD-10 diagnosis code list. Aetna's coverage policy maps specific diagnoses to covered versus non-covered territory. Visual field defects (H53.40–H53.489), ischemic optic neuropathy (H47.11–H47.19), and neurological conditions like intracranial injury (S06.0x0–S06.9x9) represent the clinical territory where medical necessity arguments are viable. These are acquired, structurally verifiable conditions — not behavioral or developmental ones.
Diagnoses tied to developmental speech and language disorders (F80.0–F80.9), specific reading disorder (F81.0), specific spelling disorder (F81.81), dyslexia and alexia (R48.0), and delayed milestone in childhood (R62.0) are the codes Aetna flags as outside covered indications for vision therapy. Billing CPT 92065 or CPT 97533 with these diagnosis codes is a fast path to claim denial.
Prior authorization requirements for behavioral vision therapy services are not explicitly detailed in the policy data available here. If your practice submits prior auth requests for CPT 92065 or 97533 to Aetna, verify current prior authorization requirements through Aetna's provider portal or your contract. Don't assume a previous approval pattern holds after the September 26 effective date.
Aetna Behavioral Vision Therapy Exclusions and Non-Covered Indications
This is the section that matters most for pediatric practices and developmental specialists. Aetna's position is consistent: vision therapy aimed at improving reading, learning, or developmental performance is not covered medical care. It's classified as experimental and investigational.
The following diagnosis groups are excluded from covered behavioral vision therapy billing under CPB 0321:
| # | Excluded Procedure |
|---|---|
| 1 | Developmental speech and language disorders (F80.0–F80.9) — all subcategories |
| 2 | Specific reading disorder (F81.0) and specific spelling disorder (F81.81) |
| 3 | Dyslexia and alexia (R48.0) |
| 4 | Delayed milestone in childhood (R62.0) |
| 5 | Voice and resonance disorders (R49.0–R49.9) |
| 6 | Body dysmorphic disorder (F45.22) |
The presence of F80, F81, and R48 codes in this policy is notable. These are exactly the diagnoses practitioners sometimes attach to vision therapy claims when arguing a visual processing component to a learning disorder. Aetna rejects that logic. If your billing team has been pairing CPT 92065 with dyslexia or reading disorder codes, stop. Those claims will not survive.
The speech-related codes — R49.0–R49.9 and Z51.89 (encounter for other specified aftercare, speech therapy) and Z87.898 (personal history of other specified conditions, speech) — appear here because CPT 97533 (sensory integrative techniques) sometimes gets used in speech-adjacent occupational therapy contexts. Aetna is not covering that pathway under this policy.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Visual field defects | Potentially Covered | H53.40–H53.489, CPT 92065 | Structural/acquired condition; document medical necessity carefully |
| Ischemic optic neuropathy | Potentially Covered | H47.11–H47.19, CPT 92065 | Verify prior auth requirements |
| Intracranial injury / neurotrauma | Potentially Covered | S06.0x0–S06.9x9, S02.0xx+–S06.92x+, CPT 97533 | Post-injury rehabilitation context; document functional deficits |
| Occlusion and stenosis of cerebral arteries | Potentially Covered | I65.01–I66.9, CPT 92065 | Stroke-related visual field loss context |
| Developmental speech/language disorders | Not Covered | F80.0–F80.9, CPT 92065, CPT 97533 | Classified as experimental for these indications |
| Specific reading disorder / dyslexia | Not Covered | F81.0, R48.0, CPT 92065 | Aetna does not accept visual processing arguments for learning disorders |
| Specific spelling disorder | Not Covered | F81.81, CPT 92065 | Same rationale as reading disorder exclusion |
| Delayed childhood milestone | Not Covered | R62.0, CPT 97533 | Not covered under this policy |
| Voice and resonance disorders | Not Covered | R49.0–R49.9, CPT 97533 | Outside covered scope for sensory integration billing |
| Body dysmorphic disorder | Not Covered | F45.22 | Behavioral diagnosis; no vision therapy coverage |
| Speech therapy aftercare / history | Not Covered | Z51.89, Z87.898, CPT 97533 | Speech-adjacent OT billing excluded |
Aetna Behavioral Vision Therapy Billing Guidelines and Action Items 2025
The effective date is September 26, 2025. That's your deadline. Here's what to do before then.
| # | Action Item |
|---|---|
| 1 | Audit your CPT 92065 and CPT 97533 claim history. Pull the last 12 months of Aetna claims for both codes. Flag any that paired these CPT codes with F80–F81, R48, or R49 diagnosis codes. These represent your denial risk exposure. |
| 2 | Update your charge capture to block non-covered diagnosis pairings. Configure your billing system to flag — or block — claims that combine CPT 92065 or 97533 with the excluded ICD-10 codes listed in this policy. This is a one-time build that prevents recurring denials. |
| 3 | Review open prior authorizations for both codes. Any active prior auth approved before September 26 may not carry the same coverage logic under the updated policy. Confirm with Aetna whether existing authorizations remain valid after the effective date. Get that in writing if you can. |
| 4 | Brief your clinical documentation team on the covered diagnosis list. The covered territory — H47.xx ischemic optic neuropathy, H53.40–H53.489 visual field defects, S06 intracranial injuries, I65–I66 cerebrovascular occlusion — requires specific, contemporaneous documentation of functional visual deficits. Generic therapy notes will not support reimbursement for these claims. |
| 5 | Check your occupational therapy billing for CPT 97533. If your OT team bills 97533 for sensory integration in pediatric or developmental contexts, confirm the diagnosis codes they're using. R49 voice disorders, R62.0 developmental delay, and F80 language disorders are all excluded. Behavioral vision therapy billing with these codes will deny. |
| 6 | Talk to your compliance officer if you have volume. If CPT 92065 or 97533 represents significant reimbursement for your practice and you serve patient populations with learning or developmental diagnoses, the risk profile here is real. Loop in your compliance officer before September 26 to assess your exposure and document your review process. |
