Millions of retirees enrolled in Original Medicare still pay the full cost of routine dental cleanings, eye exams for glasses, and hearing aids out of their own pockets. The Centers for Medicare and Medicaid Services confirms that these everyday services remain outside the program’s benefit structure, a statutory exclusion that has persisted for decades. Even after CMS expanded certain medically linked dental exceptions for dates of service starting in 2023, the core gap for routine care has not closed, and beneficiaries without supplemental coverage absorb every dollar.
Why routine dental, vision, and hearing exclusions hit retirees harder now
The financial pressure is straightforward. CMS notes that Original Medicare omits most routine services related to dental, vision, and hearing, including cleanings, fillings, extractions, dentures, implants, routine eye exams for prescriptions, hearing aids, and exams for fitting them. Beneficiaries who need any of these services pay the entire bill unless they carry a separate plan, such as a standalone dental policy, a discount program, or a Medicare Advantage plan that bundles supplemental benefits.
That distinction between Original Medicare and Medicare Advantage creates a widening split among retirees. Peer-reviewed research published in Health Affairs, drawing on 2016 Medicare Current Beneficiary Survey microdata, found that beneficiaries in Traditional Medicare faced higher out-of-pocket shares for dental, vision, and hearing services compared to those in Medicare Advantage coverage. The MCBS Cost Supplement microdata, cataloged through the federal Data.gov portal, tracks expenditures and payment sources for these non-covered services, providing a detailed window into what retirees actually spend when they seek routine care outside the core benefit package.
The hypothesis that Original Medicare enrollees face persistently higher cumulative costs for these three service categories holds up against the available evidence, but a critical limitation exists. The Health Affairs analysis relied on 2016 survey data, several years before CMS broadened medically necessary dental coverage. No publicly available update using post-2023 MCBS waves has yet confirmed whether the expanded dental exceptions changed the spending gap in a measurable way. The latest academic benchmarks therefore predate the policy shift, leaving a blind spot in the data record at the very moment when policymakers and advocates are debating how far to extend new benefits.
CMS expanded dental exceptions in 2023 but left routine care untouched
CMS billing guidance updated for services beginning in 2023 broadened the circumstances under which Medicare may pay for dental work that is “inextricably linked” to a covered medical procedure. That change, documented in CMS Medicare Coverage Database Article A59449, applies to situations such as jaw reconstruction before radiation therapy, dental clearance before organ transplant, or extractions needed to safely perform certain cardiac surgeries. In these narrow cases, Medicare can treat the dental work as part of the underlying medical episode.
Even with those changes, the core exclusions remain in place. CMS coverage pages confirm that Medicare does not pay for routine dental care such as cleanings, uncomplicated fillings, and dentures obtained for everyday function rather than as part of a major medical procedure. The same pattern holds for vision and hearing. Original Medicare does not cover standard eye exams needed to update eyeglass or contact lens prescriptions, nor does it cover hearing aids and the tests required to fit them. Each of these exclusions is rooted in statute, meaning they cannot be reversed by agency rulemaking alone. Congressional action would be required to add these benefits to Original Medicare’s basic package.
Retirees who qualify for the narrow medical-necessity exceptions represent a small fraction of the Medicare population. CMS has not released comprehensive utilization or spending figures that isolate the newly covered dental scenarios from the broader universe of non-covered services, and no federal dataset yet shows how many beneficiaries have actually benefited from the 2023 expansion. In practice, most older adults encounter dental, vision, and hearing needs as routine maintenance rather than as prerequisites for complex surgery, leaving the vast majority still outside Medicare’s reach.
Uneven protection and policy questions ahead
The result is a patchwork of protection. Retirees with the means to purchase Medicare Advantage plans that include supplemental benefits, or to buy separate standalone policies, can offset some of the cost of cleanings, eye exams, and hearing evaluations. Others rely on savings, credit cards, or family support to pay providers directly. Low-income beneficiaries who qualify for Medicaid may gain additional coverage, but eligibility rules vary by state, and adult dental and vision benefits are often limited or subject to tight caps.
For policymakers, the unresolved question is not whether a coverage gap exists, but how large it is today and which tools would close it most effectively. The 2016 MCBS-based research offers a baseline showing higher out-of-pocket burdens for Traditional Medicare enrollees, yet the absence of more recent, post-expansion data makes it difficult to quantify current exposure with precision. Until updated survey waves and claims analyses are published, debates over adding routine dental, vision, and hearing benefits to Original Medicare will continue to rely on pre-2023 benchmarks and anecdotal reports from retirees who postpone or forgo care they cannot afford.
