Medicare dental coverage expansion

Full Title:
Medicare Dental Benefit Act of 2026

Summary#

This bill adds dental and oral health services to what Medicare can cover. It defines a wide range of dental care (preventive, basic, major, emergency, and prostheses) and sets rules for how Medicare will pay for those services over time. The broad goal is to make dental care available to people on Medicare, with stronger cost coverage for low-income beneficiaries and a phased-in payment schedule for others.

  • Main change: Medicare Part B would cover routine cleanings, exams, fillings, extractions, root canals, crowns, dentures, emergency dental care, and related services.
  • Payment rule: For most people, Medicare payments for non-preventive dental services start at 0% in the first year and rise by 10 percentage points each year until reaching 80% in year 8; low-income subsidy-eligible people get 80% immediately.
  • Limits: Two cleanings and two routine exams per year; limits on how often dental prostheses (dentures/partials) are paid for (generally one full upper and one full lower, and one partial upper and one partial lower every 5 years).
  • State Medicaid rule: States get a 100% federal match for amounts they spend to help certain low-income Medicare beneficiaries with dental cost-sharing attributable to this new Medicare dental coverage.
  • Timing: The coverage and other changes start for services furnished on or after January 1, 2028.
  • Administrative authority: The Secretary of Health and Human Services is given broad authority to define services, set limits, require prior authorization, and change coverage to match preventive recommendations.

What it means for you#

  • Medicare beneficiaries: More dental services would be allowed under Medicare. Preventive services (cleanings, x-rays, exams) are called preventive services. For most beneficiaries, out-of-pocket costs for many dental services would be reduced gradually over several years. Low-income beneficiaries who meet the bill’s subsidy test would get much higher Medicare payment help immediately.
  • Low-income Medicare beneficiaries: If you are subsidy eligible (as defined under Medicare Part D low-income rules), Medicare would pay about 80% of many dental and prosthesis costs from the start. That reduces what you might have to pay or rely on Medicaid to cover.
  • People who need dentures or partials: Medicare would cover certain dental prostheses, but with limits on how often you can get them (generally once every five years).
  • Dentists and dental practices: Dentists would need to work with Medicare rules, billing, and payment rates. Early years may pay less (or nothing under Medicare for some services), which could affect whether dentists accept Medicare for those services.
  • States and Medicaid programs: When states pay Medicare cost-sharing for qualifying low-income Medicare beneficiaries for these dental services, the federal government would reimburse those state payments at 100%.
  • Patients needing frequent care or special services: The Secretary can set additional limits or require prior authorization. The bill allows the Secretary to waive limits for individuals or groups when appropriate.
  • Public health guidance: The U.S. Preventive Services Task Force must include at least one oral health professional among experts, and the Secretary may change dental coverage to follow the Task Force’s recommendations.

Expenses#

No publicly available information.

Possible expense categories shown in the bill text (no dollar amounts given):

  • Increased Medicare spending to pay for dental services and prostheses, rising over the first 8 years as payment percentages increase.
  • Additional federal spending because states get a 100% federal match for Medicaid payments that cover Medicare cost-sharing for qualifying low-income beneficiaries.
  • Administrative costs for CMS to define covered dental services, set payment rates, enroll providers, manage claims, run prior authorization systems, and monitor limits.
  • Potential costs or lower revenue for dental providers if Medicare payment rates are low or phased in slowly, which could affect provider participation.
  • Possible savings to some individuals and to state Medicaid programs (for those qualifying) because federal payments would cover more of the cost.

Proponents' View#

The bill text suggests these main goals and possible benefits:

  • The bill appears intended to fill a gap by making dental care an explicit part of Medicare coverage. This could improve oral health for people on Medicare.
  • It could reduce the financial burden of dental care for low-income Medicare beneficiaries by providing 80% coverage for them immediately.
  • Adding preventive dental care as a Medicare preventive service may encourage earlier detection and treatment of dental problems.
  • Giving the Secretary authority to align coverage with the U.S. Preventive Services Task Force could let coverage follow updated, evidence-based guidance.
  • The 100% federal match for state payments for Medicare cost-sharing reduces costs for states that help low-income Medicare beneficiaries access dental care.

Opponents' View#

The bill’s design raises several practical concerns based on its text:

  • One concern is cost: the bill will increase federal spending for Medicare and for federally matched Medicaid payments, but it does not include a fiscal estimate in the text.
  • The phased-in payment schedule starts at 0% for many services in the first year. This could mean Medicare covers the service in law but pays little or nothing initially, which may discourage dentists from participating and limit access early on.
  • The Secretary has broad authority to add limits, require prior authorization, or modify coverage. That flexibility could result in access limits that vary or are unclear until regulations are written.
  • Frequency limits (for cleanings, exams, and prostheses) may not fit every patient’s medical needs. The bill allows waivers, but how waivers are granted is not detailed.
  • Key details are left to the Secretary (exact service definitions, payment rates, prior authorization rules). The bill does not explain how dentists will enroll in Medicare, how existing Medicare Advantage dental benefits interact with this change, or how coordination with state Medicaid dental programs will work.

What is unclear: Several important implementation points are not spelled out in the bill text, including exact payment amounts under the Medicare payment basis, provider enrollment rules, how Medicare Advantage plans would handle dental benefits, and the fiscal impact.
