Millions of Americans who rely on Original Medicare for their health coverage face a gap that catches many off guard: the program does not pay for routine dental cleanings, eye exams for prescription glasses, or hearing aids. These are not obscure exclusions buried in fine print. They are written directly into federal law under Social Security Act Section 1862(a)(12) and reinforced by federal regulation at 42 CFR 411.15, leaving beneficiaries to cover the full cost of everyday care out of their own pockets.
Why the dental, vision, and hearing gap hits harder in 2026
The exclusion is not a bureaucratic oversight or a temporary policy choice. The Centers for Medicare & Medicaid Services states plainly on its page describing what is not covered that Original Medicare does not pay for routine dental care, eye exams for prescription eyeglasses, or hearing aids and exams for fitting them. That means cleanings, fillings, extractions, dentures, implants, refractions, and hearing device fittings all fall outside Parts A and B.
For beneficiaries who also qualify for Medicaid, known as dual eligibles, state programs can fill some of these gaps. States that offer adult dental benefits through Medicaid and automatically enroll dual eligibles into those benefits could, in theory, reduce the number of people who delay care until a dental infection sends them to the emergency room. No federal dataset currently isolates emergency-department visit rates for dental infections by state enrollment policy, so the precise size of that effect remains unmeasured. What is clear is that beneficiaries in states without such automatic enrollment have fewer safety nets and face the full weight of Medicare’s exclusions alone.
These gaps land at a time when inflation and post-pandemic backlogs have pushed up the price of care. A single crown, pair of prescription lenses, or modern hearing aid can cost hundreds or even thousands of dollars, and providers frequently require payment at the time of service. For retirees on fixed incomes, the result is often a choice between skipping care or taking on new debt, rather than a straightforward copay at the doctor’s office.
Federal statute and regulation behind the exclusions
The legal foundation for these coverage gaps is specific and longstanding. CMS cites Medicare dental guidance as grounded in SSA Section 1862(a)(12) and 42 CFR 411.15(i), the controlling authorities for the dental exclusion. The statutory text, published by the Social Security Administration, lists categories of services that Medicare will not pay for, and routine dental care sits squarely within those categories. The same section of law also underpins limits on routine eye and hearing services.
Reading the underlying statute, Section 1862(a) makes clear that Medicare may not pay for services “where such expenses are for items or services” excluded by Congress, including most dental treatment. A CMS training module for Parts A and B echoes this language and confirms that the program does not generally cover dental care, dentures, routine eye care, refractions, most eyeglasses, or certain hearing services.
Narrow exceptions exist. Medicare may pay for dental work that is directly tied to a covered medical procedure, such as jaw reconstruction after an accident or dental exams required before organ transplant surgery. Dental services that are integral to radiation treatment for oral cancer can also fall within covered care if they are part of the physician’s treatment plan. But these exceptions do not extend to the preventive and maintenance care that most people need on a regular basis. A routine cleaning before a scheduled knee replacement, for example, would not qualify, even if a surgeon recommends it.
What beneficiaries still cannot resolve on their own
Several questions remain open. CMS has not published a cost-benefit analysis comparing health outcomes for beneficiaries who purchase supplemental dental, vision, and hearing coverage against those who go without. No official beneficiary survey from CMS or the Social Security Administration measures how many Original Medicare enrollees are even aware of these exclusions before they need care. And no publicly available claims dataset breaks out how many beneficiaries forgo routine dental, vision, or hearing services each year because of cost.
Without that data, policymakers and beneficiaries alike are working with incomplete information. Legislative proposals to add dental, vision, and hearing benefits to Medicare must rely on partial estimates, often extrapolating from private insurance markets or state Medicaid programs. Beneficiaries, for their part, are left to decide whether to buy standalone coverage, enroll in a Medicare Advantage plan that includes limited extra benefits, or pay cash as needs arise, all without clear federal guidance on typical utilization or financial risk.
Until Congress changes the underlying statute, the exclusions in Section 1862(a)(12) and related regulations will continue to define what Original Medicare does not pay for. That leaves millions of older adults and people with disabilities navigating some of their most common health needs-routine dental work, updated eyeglass prescriptions, and hearing support-outside the core federal program they expected would protect them in retirement.
