Understanding The Gaps
Medicare provides essential health coverage for millions of Americans, but it wasn't designed to cover everything. Understanding its gaps is one of the most important steps in retirement planning.
If you're approaching Medicare eligibility or helping a loved one navigate their coverage, you may be surprised by how much Original Medicare (Parts A and B) leaves out. From routine dental cleanings to nursing home stays, the coverage gaps can be significant and costly. Below, I break down what Medicare doesn't cover.
Coverage Gaps at a Glance
Dental, Vision & Hearing: Most routine and restorative care excluded
Long-Term Care: Custodial and nursing home stays not covered
Prescription Drugs: No coverage without Part D enrollment
Overseas Care: Most services outside the U.S. excluded
Experimental & Cosmetic: Unapproved procedures not covered
No Out-of-Pocket Max: No annual spending cap under Parts A & B
Dental, Vision, and Hearing Services
Original Medicare generally does not cover routine dental care, that means no coverage for cleanings, fillings, extractions, dentures, or implants. Similarly, Medicare doesn't pay for routine eye exams, eyeglasses, or contact lenses (with limited exceptions for certain eye conditions). Hearing aids and routine hearing exams are also excluded.
These are not minor omissions. Adults 65 and older have significant rates of tooth loss, vision impairment, and hearing loss; all of which affect quality of life and overall health. Without additional coverage, these out-of-pocket costs can be substantial.
Available options: Beneficiaries may explore supplemental coverage for dental, vision, and hearing needs through various insurance products or plans available in their area.
Long-Term Care and Custodial Services
This is perhaps the most significant gap in Medicare coverage. Medicare will not pay for long-term custodial care, such as assistance with daily activities like bathing, dressing, eating, or using the restroom, whether that care is provided at home or in a nursing facility.
Medicare does cover short-term skilled nursing facility care following a qualifying hospital stay (at least three inpatient days), but only for up to 100 days, and with significant cost-sharing after day 20. Once skilled care needs end or benefits are exhausted, Medicare stops paying.
The annual median cost of a private nursing home room exceeds $100,000. For many retirees, this is the most financially devastating gap in their coverage.
Available options: Various insurance products and planning strategies exist to help address long-term care costs, including specialized insurance policies and Medicaid planning for those who qualify.
Prescription Drugs
Original Medicare (Parts A and B) does not cover most outpatient prescription drugs. While Part B does cover certain medications administered in a clinical setting (such as chemotherapy or injections given in a doctor's office), the vast majority of drugs you pick up at a pharmacy are not included.
To get drug coverage, Medicare beneficiaries must enroll in a standalone Part D prescription drug plan or choose a Medicare Advantage plan that includes drug coverage. Failing to enroll in Part D when first eligible can result in a permanent late enrollment penalty added to your premium.
Available options: Part D prescription drug plans and Medicare Advantage plans with drug coverage are available during Annual Enrollment (Oct. 15–Dec. 7) each year, as formularies and premiums change annually.
Care Received Outside the United States
With limited exceptions, Medicare does not cover health care services received outside the United States and its territories. This can be a significant concern for retirees who travel internationally or spend extended periods abroad.
The limited exceptions include emergency care in Canada if you're traveling through Canada between Alaska and another U.S. state, or if you're aboard a ship within six hours of a U.S. port.
Available options: Travel health insurance and certain supplemental coverage plans include provisions for foreign travel emergency care up to specific plan limits for those who travel internationally.
Experimental Treatments and Cosmetic Procedures
Medicare covers medically necessary services, not experimental, investigational, or cosmetic ones. Treatments that haven't been approved or accepted as standard medical practice are generally not covered, even if your doctor recommends them.
Cosmetic surgery is similarly excluded unless it's required to correct a condition resulting from accidental injury or to improve the functioning of a malformed body part.
Available options: If you're exploring a treatment that may be considered experimental, talk with your physician about clinical trial options. Medicare does cover routine costs for beneficiaries enrolled in qualifying clinical trials.
Preventive Services Outside Medicare's Scope
Medicare covers a broad range of preventive screenings and wellness services, such as Annual Wellness Visits, cancer screenings, flu shots, and more. However, not every preventive service is covered, and coverage rules can be specific.
For example, general physicals (other than the one-time "Welcome to Medicare" visit) are not covered. Certain vitamins, supplements, and lifestyle programs also fall outside what Medicare will pay for.
Important: Coverage rules can affect your out-of-pocket cost, so asking your provider to code a visit appropriately matters.
No Annual Out-of-Pocket Maximum
One of the most under-appreciated risks in Original Medicare is the absence of an annual out-of-pocket maximum. Under Parts A and B, there is no cap on how much you can spend in a given year. A serious illness or multiple hospitalizations could result in unlimited cost exposure.
This stands in contrast to most private insurance plans and Medicare Advantage plans, which are required to have an out-of-pocket maximum.
Available options: Supplemental coverage and Medicare Advantage plans are available that include annual out-of-pocket maximums to help cap your exposure.
Understanding Your Choices
Medicare is a strong foundation, but it works best when paired with additional coverage. Various options exist to address gaps in Original Medicare coverage, including Medicare Supplement plans, Medicare Advantage plans, Part D prescription drug plans, long-term care insurance, and standalone dental and vision plans.
The right approach depends on individual health needs, budget, preferred providers, and risk tolerance. A licensed Medicare advisor can explain coverage options available in your area.
