Vestibular Autorotation Test (VAT) — CPB 0467 | AETNA Coverage Update

Aetna modified CPB 0467 covering vestibular autorotation test (VAT), effective September 26, 2025. Here's what billing teams need to know.

Aetna, a CVS Health company, updated Clinical Policy Bulletin 0467 governing its vestibular autorotation test coverage policy. This change affects CPT codes 92541 through 92548 — the full range of vestibular function test codes — and applies to any claim where VAT testing is billed for diagnoses including Meniere's disease, vestibular migraine, peripheral vertigo, dizziness, or syncope. If your practice bills these codes for Aetna members, this update changes how you document and justify medical necessity.

Aetna Vestibular Autorotation Test Coverage Criteria and Medical Necessity Requirements 2025

CPB 0467 addresses vestibular autorotation test (VAT) coverage under Aetna plans. The full policy text of CPB 0467 defines the specific coverage criteria, medical necessity requirements, and clinical standards that apply to these claims.

The published policy summary for this modification does not reproduce those criteria in full. To understand exactly what Aetna requires for CPT 92541–92548 to be payable, your billing and compliance teams need to review the complete CPB 0467 document directly through Aetna's provider portal.

The ICD-10 codes attached to this policy tell you which diagnoses Aetna references in CPB 0467. Those codes span Meniere's disease, peripheral vertigo, vestibular migraine, dizziness, and syncope — but a listed diagnosis code alone does not equal a covered claim. The full policy text governs what documentation and clinical criteria are required alongside the diagnosis.

Aetna Vestibular Autorotation Test Exclusions and Non-Covered Indications

CPB 0467 defines which VAT indications Aetna considers covered, non-covered, or investigational. Those exclusions and non-covered indications are contained in the full policy text — not reproduced in this modification summary.

Review the complete CPB 0467 document on Aetna's provider portal before submitting claims under CPT 92541–92548. Your compliance officer should confirm how the updated exclusion language applies to your specific claim mix.

CPT, HCPCS, and ICD-10 Codes for Vestibular Autorotation Test Under CPB 0467

CPT Codes — Vestibular Function Tests

These eight codes are designated in CPB 0467 as "other CPT codes related to the CPB." That classification matters. It signals that Aetna is not listing these as unambiguously covered codes — they're relevant codes that billing teams and reviewers should know are in scope for this policy.

Key ICD-10-CM Diagnosis Codes

The source policy lists H81.1 through H81.9 as Meniere's disease codes and H81.10–H81.399 separately as other and unspecified peripheral vertigo. These are distinct groupings — do not apply the Meniere's disease label to the H81.10–H81.399 range.

The breadth of this ICD-10 list reflects how many different clinical presentations lead to a VAT order. But a wide diagnosis list is not the same as wide coverage. The full CPB 0467 document defines what Aetna requires alongside the diagnosis code for a claim to be payable.
