Original Medicare covers one diagnostic hearing exam every 12 months without a doctor’s order, and additional exams whenever your doctor orders them to investigate a medical concern. The key distinction is whether the test is considered “diagnostic” or “routine,” because that determines both how often you’re covered and how much you’ll pay.
The Once-a-Year Direct Access Rule
Starting in 2023, Medicare created an exception that lets you see an audiologist directly, without a physician’s referral, once every 12 months. This annual visit covers diagnostic testing for non-acute hearing conditions, meaning gradual hearing loss that develops over months or years. It also covers diagnostic services related to hearing loss that might be treated with surgically implanted devices like cochlear implants.
This was a significant change. Before 2023, every hearing exam under Medicare required a doctor’s order. Now you can schedule one annual visit on your own, which removes a barrier for people who suspect their hearing has declined but haven’t brought it up with their primary care provider yet.
There’s one important limitation: this direct-access visit doesn’t cover testing for dizziness or balance problems. If you’re experiencing vertigo or frequent falls, you’ll still need a physician’s order for those balance-related exams.
Doctor-Ordered Tests Have No Frequency Cap
When your doctor or another healthcare provider orders a diagnostic hearing or balance exam because they suspect you need medical treatment, Part B covers it. There’s no once-a-year limit on these physician-ordered tests. If your doctor needs hearing results to diagnose an ear infection, monitor a neurological condition, evaluate sudden hearing loss, or assess you for a cochlear implant, Medicare will cover the exam regardless of when you last had one.
The critical word here is “diagnostic.” Medicare draws a firm line between a test ordered to investigate a medical problem and a routine screening just to check how your hearing is doing. Routine hearing screenings and hearing aid fittings are explicitly excluded from Original Medicare coverage. So if you walk into an audiologist’s office asking for a basic hearing check with no medical symptoms and you’ve already used your annual direct-access visit, you’d likely pay out of pocket.
What You’ll Pay for Covered Tests
For covered diagnostic hearing exams, standard Part B cost-sharing applies. You’ll pay 20% of the Medicare-approved amount after meeting your annual Part B deductible. The audiologist or facility must accept Medicare assignment for these rates to apply, so it’s worth confirming that before your appointment.
If the exam isn’t considered medically necessary or doesn’t qualify under the direct-access rule, Medicare won’t pay anything. You’d be responsible for the full cost, and the provider should give you an advance notice explaining that Medicare may not cover the service.
What Medicare Won’t Cover
Original Medicare does not cover hearing aids or the exams specifically for fitting hearing aids. This is a statutory exclusion that has been in place for decades. The annual diagnostic exam can identify and document your hearing loss, but the moment the purpose shifts to selecting or fitting a hearing aid, coverage stops.
This creates a frustrating gap for many beneficiaries. You can get tested and learn exactly how much hearing you’ve lost, but the most common solution, a hearing aid, isn’t covered. Cochlear implants are a different story. Medicare covers cochlear implantation for people with bilateral moderate-to-profound sensorineural hearing loss who score 60% or lower on open-set sentence recognition tests in their best-aided condition. But this applies to a relatively small subset of people with hearing loss.
Medicare Advantage May Cover More
Medicare Advantage plans (Part C) are required to cover everything Original Medicare covers, including the annual direct-access hearing exam and doctor-ordered diagnostic tests. Many plans go further by offering additional hearing benefits that Original Medicare excludes, such as routine hearing screenings, hearing aid allowances, and fitting exams.
The specifics vary widely between plans. Some Medicare Advantage plans cover one pair of hearing aids every one to three years with a fixed dollar allowance. Others include additional hearing exams beyond the standard annual visit. If hearing coverage matters to you, compare the hearing benefits in your plan’s evidence of coverage document, because there’s no standard package across Advantage plans.
Dual Eligibility Can Fill Some Gaps
If you qualify for both Medicare and Medicaid, your state Medicaid program may cover hearing services that Medicare excludes. About 71% of dual-eligible beneficiaries age 65 and older live in a state where Medicaid offers hearing aid benefits. Coverage varies significantly by state: some provide hearing aids and related fitting exams, while others offer limited or no hearing benefits for adults.
For dual-eligible beneficiaries, Medicare remains the primary payer for diagnostic hearing exams, and Medicaid can potentially pick up hearing aids and additional services. Contact your state Medicaid office to find out what’s available where you live, since these benefits changed substantially across many states between 2017 and 2023.
How to Get the Most From Your Coverage
If you’ve noticed gradual hearing loss, you can go directly to a Medicare-participating audiologist once a year without needing to visit your doctor first. Book that annual visit and use it. If your hearing changes suddenly or you develop new symptoms like ringing, pain, or dizziness between annual visits, see your doctor. They can order a diagnostic exam at any point, and Medicare will cover it as long as it’s tied to a medical concern.
Keep in mind that the audiologist needs to bill the visit correctly for Medicare to pay. For direct-access visits, they use a specific billing modifier (AB) to indicate no physician order was involved. If there’s a billing error, you could receive a surprise denial. Make sure the audiologist’s office knows you’re using your annual direct-access benefit before the appointment, so they code it properly from the start.
