Jun 20, 2026
Summary
This policy confirms that transtympanic micropressure applications (Meniett device) for treating Meniere disease are considered not medically necessary. The policy has not changed from its previous stance - it remains a non-covered treatment with specific HCPCS codes that should not be billed as they will be denied.
Action Required
Billing team should ensure these codes are flagged in the system as non-covered: HCPCS A4638 (replacement battery for ear pulse generator) and E2120 (pulse generator system for tympanic treatment). Verify claims with these codes are not submitted as they will be denied for not being medically necessary.
