How Long Do Hearing Aids Last? What Payers' Replacement Rules Say

Why this page gives no lifespan average

Ask how long hearing aids last and the first answers come from ear, nose and throat practices, hearing centers and a health-financing company, each with its own range of years. We don't repeat one here. The government documents we read for this page, from the Department of Veterans Affairs, four state Medicaid programs and the Centers for Medicare & Medicaid Services (CMS), measure no device's lifespan. What they write down is narrower, and more useful once a replacement has to be paid for: the conditions under which a program buys a new aid, and how often.

Keep the two ideas apart. A five-year Medicaid limit says how often the program will pay, not that a device wears out after five years. A Medicare Advantage cap that resets every two years sets the most a plan pays in that window, not a date on which new aids arrive. Montana's manual shows where the pieces meet: it replaces an adult's aid once within five years only if the aid was lost or irreparably broken after the warranty period, so the warranty comes first.

VA: replacement follows the device's condition, not a calendar

For veterans, the rule is a list of conditions rather than an interval. The VHA hearing aid directive dated October 2019 says devices "will be replaced when the instrument proves to be ineffective, irreparable, or the Veteran's medical condition has changed and a different device is needed." It adds that devices "will not be replaced because a new make or model is available," and that a lost or destroyed device may be replaced when the loss was beyond the Veteran's control. The directive remains national policy until it is recertified or rescinded.

Spare aids, battery orders and repair requests follow their own VA rules: our page on how often the VA replaces hearing aids sets them out, and VA hearing aids covers who can get them.

Medicaid: five years between adult hearing aids in four states

State Medicaid programs write the clearest intervals. The four rules we read all land on five years for adults, each with a different condition attached:

• Washington covers one new monaural hearing aid, ear mold included, "every five years for clients age twenty-one and older."
• Minnesota covers "one hearing aid or set of binaural hearing aids within a period of five years for an eligible member aged 21 years and over." A replacement for a change in hearing, loss, theft or irreparable damage goes through an authorization request from the provider, and the manual sets no replacement limit for children.
• Montana replaces an adult's aid once within five years, only when it was lost or irreparably broken after the warranty period and the provider's records document it.
• Indiana limits replacement hearing aids to once every five years and allows prior authorization for more frequent replacement only for members under 21.

These limits sit on top of each program's clinical, prescription and eligibility conditions, which we don't reproduce. A five-year line in a rule doesn't mean a new aid arrives on that date: Minnesota and Montana both tie replacement to a request and a documented reason. Your state Medicaid agency, or its managed care plan, gives the answer for your case; our Medicaid page lists more state rules.

Medicare Advantage: a cap period is not a replacement date

Medicare Advantage plans file their hearing aid benefits with CMS, and many file a cap: the most the plan will pay toward hearing aids, per ear or for both ears, within a set period. In the 2026 plan benefit files, that period differs from plan to plan:

• Alabama: 12 of the state's 98 plan segments file a per-ear cap that resets every year (median $500), and 7 file a cap for both ears every two years (median $2,200).
• Arkansas: 25 of 91 segments file a yearly per-ear cap (median $500); 5 file a two-year cap for both ears (median $1,500) and 3 a three-year cap for both ears (median $1,000).
• California: of 402 segments, 54 file a yearly per-ear cap (median $600) and 53 a yearly cap for both ears (median $3,000); smaller groups file caps over two years (10 segments, both ears, median $1,500) or three years (5 segments for both ears, median $4,000; 5 per ear, median $1,000).

Read each period as a spending limit. A plan whose cap resets every three years isn't saying that aids last three years, and a yearly reset doesn't buy new aids every year: copays, approved providers and the plan's own terms apply, and they sit in each plan's Evidence of Coverage. These are counts of plan segments, not of members, and a multi-state plan appears in each state it serves. We don't name or compare plans; our Medicare Advantage page covers every state.

Warranties: the maker's contract comes first

Warranties are contracts with the maker or the seller, and their terms vary by device. One example in writing: the user guide of Unitron's Insera S says "Sonova AG offers a one year limited international warranty," counted from purchase, and sends the wearer to the hearing care professional who supplied the aids for the terms of the local warranty. That international warranty isn't a U.S. return period, and it doesn't cover the professional's services.

The Montana rule above shows why the paper matters: the state replaces an adult's aid only when it was lost or broken beyond repair after the warranty period. When an aid stops working, the warranty card or contract that came with it is the first document to read, before any program's rule.
