Millions of Americans enrolled in Original Medicare face the full cost of dental cleanings, eyeglasses, and hearing aids out of their own pockets. Federal law bars the program from paying for these routine services, and a bill introduced in the 119th Congress to change that has not advanced. The gap leaves beneficiaries who do not carry supplemental coverage responsible for preventive care that most employer and marketplace plans already include.
Why the federal dental, vision, and hearing exclusion hits harder in 2025
The exclusion is not a bureaucratic oversight. It is written into Section 1395y of Title 42, the statute that lists services Medicare cannot pay for. That section of the Social Security Act specifically bars payment for routine eye exams tied to eyeglass prescriptions, hearing aids and the exams needed to fit them, and most dental procedures. A separate federal regulation, 42 CFR 411.15, spells out the dental exclusion in detail, reinforcing that cleanings, fillings, extractions, dentures, and implants fall outside the program’s reach.
The practical result is straightforward: a beneficiary who relies solely on Parts A and B and needs a tooth pulled or a new pair of glasses pays the entire bill. Medicare Advantage plans may bundle dental, vision, and hearing extras, but those benefits vary by insurer and plan year. Beneficiaries in Original Medicare who do not purchase a standalone dental or vision policy have no federal safety net for these services.
These gaps are becoming more visible as inflation and higher provider fees push out-of-pocket costs upward. A single crown or set of dentures can rival a month of rent in many regions. For retirees living on fixed incomes, the choice may be between addressing a cracked tooth or paying for utilities. Similar tradeoffs surface when beneficiaries delay eye exams because they cannot afford new lenses, or postpone hearing evaluations until communication problems start to erode work, caregiving, or social connections.
One hypothesis worth tracking is whether states that expanded adult Medicaid dental benefits after 2020 are reducing emergency dental visits among people dually eligible for Medicare and Medicaid. If so, the pattern would suggest that state spending is absorbing costs the federal exclusion shifts onto individuals and hospital emergency departments. No published federal dataset currently isolates that effect, so the question remains open.
Statute, regulation, and a stalled Senate bill
CMS ties the dental exclusion directly to Section 1862(a)(12) of the Social Security Act. The agency’s own guidance on non-covered services confirms that Medicare does not pay for routine dental care such as cleanings, fillings, extractions, dentures, or implants. Limited exceptions exist only when dental work is connected to a covered medical procedure, such as jaw reconstruction before radiation treatment or dental care required during an inpatient hospital stay when the dental service is integral to the medical treatment.
The same exclusion logic applies to vision and hearing. CMS defines a routine eye exam as an overall eye health screening that looks for signs of vision problems or disease, and states plainly that Medicare does not cover it when performed for glasses or contact lenses. Hearing aids and fitting exams are excluded under a parallel provision traceable to Section 1862(a)(7) of the Social Security Act, leaving beneficiaries to pay the full cost unless they have additional coverage.
Lawmakers have tried to close the gap. S.939, the Medicare Dental, Hearing, and Vision Expansion Act of 2025, was introduced in the 119th Congress and proposes adding all three benefit categories to Medicare beginning in future years. The bill would treat dental, vision, and hearing services more like other Part B benefits, with defined coverage standards and cost sharing. Its introduction signals that members of Congress view the current exclusions as incomplete, but the legislation has not reached a floor vote in either chamber, and no companion measure has cleared committee.
What dual eligibles and solo enrollees still lack
Several questions remain unanswered by available federal data, but the outlines of who is most exposed are clear. People enrolled only in Original Medicare and a Part D drug plan, without Medigap or employer-sponsored retiree coverage, face the most direct financial risk. Every cleaning, filling, or pair of bifocals must be paid for out of pocket or financed through private standalone policies that may carry waiting periods and annual caps.
Dual eligibles-people who qualify for both Medicare and Medicaid-have somewhat more protection, but it depends heavily on where they live. Some states offer comprehensive adult dental benefits under Medicaid, while others limit coverage to emergency extractions or provide no routine care at all. When Medicaid does not fill the gap, low-income beneficiaries can still end up in emergency rooms for preventable dental infections that Medicare will treat only after they become medical crises.
For all groups, the structure of the exclusion encourages delayed care. Skipping routine cleanings can turn minor cavities into root canals or extractions. Forgoing eye exams can leave glaucoma or diabetic retinopathy undetected until vision loss occurs. Untreated hearing loss has been linked in clinical research to social isolation and cognitive decline, yet the up-front cost of hearing aids remains a barrier for many older adults.
Until Congress changes the underlying statute, Medicare’s position is unlikely to shift. The core program will continue to cover medically necessary hospital and physician services while leaving routine dental, vision, and hearing care to a patchwork of state programs, private plans, and personal savings. For beneficiaries, understanding that limitation-and planning for it-remains as important in 2025 as it was when the exclusions were first written into law.
