Hearing Aid denials: what the review data shows
Independent reviewers have decided 25 published cases where an insurer denied Hearing Aid — and they overturned the insurer 36% of the time. A denial for Hearing Aid is a starting position, not a final answer.

Conditions behind hearing aid denials

What the insurer actually argued
Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 22 | 36.4% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 3 | 33.3% |

What the reviewers wrote
Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for hearing aids with masking sounds. Recent literature explains that tinnitus is the perception of phantom sound in the absence of a corresponding external source. It is a highly prevalent disorder, and most cases are caused by cochlear injury that leads to peripheral deafferentation, which results in adaptive changes in the CNS. Tinnitus is a heterogeneous disorder, tinnitus sound can differ between individuals, it can result from many different types of injury and its effect can vary from a minor annoyance to catastrophic impact on daily life.
Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for hearing aids. Findings: The physician reviewer found that hearing aids are the most common treatment for hearing loss. Hearing aids allow for greater improvements in speech recognition and localization. Hearing aids for those with severe hearing loss are essential for speech comprehension. A recent study explored unilateral versus bilateral hearing aids for the treatment of asymmetrical hearing loss. This study found that using hearing aids in both ears is preferable, as wearing one hearing aid on the poorer ear was shown to result in significantly worse performance in speech in noise testing. Also, this study concluded that bilateral hearing aids were preferable for asymmetrical hearing loss to restore hearing in the most natural way.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for durable medical equipment (DME) hearing aids/molds for the left ear CROS system hearing aid for treatment of the enrollee’s bilateral sensorineural hearing loss. Findings: The physician reviewer found that a CROS hearing device is utilized for a patient’s hearing improvement when there is a sudden change of hearing unilaterally. The DME requested includes one device that serves as a microphone to pick up ambient sounds on one side of the head, and the other device serves to send the messages received into the good hearing ear by routing the signals received from one device to the other side. With this technology, the patient’s good ear can hear sounds from both sides of the head with improvement of hearing.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a right ear hearing aid. There is a lack of consensus on the criteria for hearing aid candidature and variability in the use of hearing aids in clinical practice among patients with mild hearing loss. In a study to assess the long-term effectiveness of interventions to promote the use of hearing aids, Barker and colleagues found that “There was no evidence of a statistically or clinically significant effect on hearing handicap, hearing aid benefit or the use of verbal communication strategies in the short to medium term.” In this case, the patient has normal hearing in her right ear, with a speech reception threshold of 10 dB, indicating that she can hear 50% of the words at a 10 dB level, which is quieter than a whisper, and 100% word discrimination at conversational speech levels.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this treatment generally, not any individual case.
How to use this in your appeal
These are outcomes from California’s external review program — an independent physician panel that binds the insurer. Every state has an equivalent process, and internal appeals succeed even more often. Cite the outcome record for Hearing Aidwhen you appeal: reviewers routinely find that denials like yours didn’t hold up.
