Hearing Aids and Auditory Implants | UHC Coverage Update

TL;DR: UnitedHealthcare modified its hearing aids and auditory implants coverage policy for Medicare Advantage, effective September 26, 2025. Here's what billing teams need to do.

UnitedHealthcare updated the hearing-aids-auditory-implants Medicare Advantage medical policy, reinforcing coverage boundaries for osseointegrated implants and auditory devices billed under CPT 69714 and HCPCS codes L8690, L8691, and L8692. The policy draws a hard line between covered prosthetic implants and excluded hearing aids — a distinction that directly determines reimbursement and claim denial risk. If your audiology or ENT practice bills these codes under Medicare Advantage, this update is worth reviewing now.

UnitedHealthcare Hearing Aids and Auditory Implants Coverage Criteria and Medical Necessity Requirements 2025

The core of this coverage policy hasn't changed philosophically — but the updated policy text spells out the medical necessity threshold more explicitly than older versions. That matters for billing teams who need clean documentation to back up claims.

Auditory implants are covered as prosthetic devices under Medicare Part B when hearing aids are medically inappropriate or can't be used. The policy identifies four specific conditions that support this finding: congenital malformations, chronic disease, severe sensorineural hearing loss, or prior surgery. Your clinical documentation must point to at least one of these. "Patient has hearing loss" doesn't clear the bar.

UnitedHealthcare recognizes two categories of covered implants under this coverage policy. First, cochlear implants and auditory brainstem implants — devices that replace the function of cochlear structures or the auditory nerve and deliver electrical energy to auditory nerve fibers through implanted electrode arrays. Second, osseointegrated implants — devices implanted in the skull that replace the function of the middle ear and transmit mechanical energy to the cochlea via a mechanical transducer. Examples include the Baha® System, Ponto® System, and Bonebridge® System.

For osseointegrated implants specifically, the device must be used in accordance with FDA-approved labeling. The policy points to the Medicare Benefit Policy Manual, Chapter 14, §10 for device coverage standards, and Chapter 16, §100 for the auditory implant rules. If you're billing CPT 69714 — implantation of an osseointegrated implant in the skull with percutaneous attachment to an external speech processor — both of these chapter references are relevant to your documentation.

The policy also references the Medicare Benefit Policy Manual, Chapter 15, §120 for repair, maintenance, and replacement of prosthetic devices. If your team bills L8691 for a replacement external sound processor, that chapter governs what's billable and when.

Prior authorization requirements aren't explicitly detailed in this policy document. Check the member's specific plan benefits and your UnitedHealthcare provider agreement before submitting claims. When in doubt, verify prior auth requirements through UHC's provider portal before the procedure date.

UnitedHealthcare Hearing Aid Exclusions and Non-Covered Indications

This is where billing teams get burned. The exclusions in this policy are broader than most expect.

Section 1862(a)(7) of the Social Security Act excludes hearing aids from Medicare coverage — full stop. UnitedHealthcare's policy restates this directly, citing 42 CFR 411.15(d). No payment is available under Part A or Part B for hearing aids or for examinations to prescribe, fit, or change hearing aids.

The policy defines hearing aids broadly. Air conduction devices that deliver acoustic energy to the cochlea via the tympanic membrane are hearing aids. Bone conduction devices that deliver mechanical energy to the cochlea via scalp stimulation — or by direct contact with the tympanic membrane or middle ear ossicles — are also hearing aids. These are not prosthetics. They don't replace organ function; they amplify sound.

Totally implantable middle ear hearing systems fall into the excluded category. The Esteem® Implantable Hearing System is named explicitly as a non-covered device. Medicare has no National Coverage Determination (NCD) for totally implantable middle ear hearing systems, and no local coverage determination (LCD) or local coverage article (LCA) exists at this time. That means there's no pathway to coverage through a Medicare Administrative Contractor, either.

The real risk here is misclassification. A billing team that codes a bone-anchored hearing device as an osseointegrated implant — when it's actually functioning as a hearing aid — will get a claim denial. The clinical and billing distinction turns on whether the device replaces middle ear function (covered) or amplifies sound to compensate for hearing loss (not covered). If you're not certain which category a device falls into, loop in your compliance officer before billing.

One more thing: some UnitedHealthcare Medicare Advantage members carry a supplemental hearing aid benefit. Always check the member's Evidence of Coverage before concluding a hearing aid claim has no path to reimbursement. The EOC may change the answer entirely.

CPT, HCPCS, and ICD-10 Codes for Hearing Aids and Auditory Implants Under hearing-aids-auditory-implants

Covered CPT Codes (When Medical Necessity Criteria Are Met)

Covered HCPCS Codes (When Medical Necessity Criteria Are Met)

ICD-10-CM codes are not listed in this policy. Your diagnosis coding should reflect the specific underlying condition supporting medical necessity — such as severe sensorineural hearing loss, congenital malformation, or chronic ear disease. Talk to your coding team or compliance officer about appropriate diagnosis code selection.
