What Does Medicare Not Cover, and How Do I Fill the Gaps?

Why Understanding Medicare Gaps Matters

Medicare is the foundation of health coverage for most Americans 65 and older. But there is a common and costly misunderstanding: many people assume Medicare covers everything. It does not. Knowing where the gaps are, and having a plan to fill them, can save you thousands of dollars and a great deal of stress.

This guide walks through the most important things Medicare does not cover, explains your options for filling those gaps, and points to Oklahoma-specific resources that can help.

What Does Original Medicare Actually Cover?

Original Medicare has two parts. Part A covers inpatient hospital stays, skilled nursing facility care (up to 100 days per benefit period after a qualifying hospital stay), hospice care, and some home health care. Part B covers doctor visits, outpatient care, preventive services like flu shots and cancer screenings, durable medical equipment, and some mental health services.

Together, Parts A and B form a strong base. But several categories of care fall outside that base entirely.

The Major Gaps: What Medicare Does Not Cover

Dental, Vision, and Hearing

Original Medicare does not cover routine dental care (cleanings, fillings, extractions, dentures), routine eye exams for glasses or contacts, or hearing aids and related fitting exams. These are among the most common health needs for adults over 55, and the costs add up quickly. A single pair of hearing aids can run $2,000 to $7,000 out of pocket.

Long-Term Custodial Care

This is the gap that catches the most families off guard. Medicare does not pay for ongoing help with daily activities like bathing, dressing, eating, or supervision for someone with dementia. Whether that care happens at home, in an assisted living facility, or in a nursing home, Medicare does not cover it once skilled medical care is no longer the primary need. According to the U.S. Department of Health and Human Services, about 56 percent of Americans turning 65 today will need some form of long-term care in their lifetime.

Care Outside the United States

With limited exceptions (certain situations in Canada and Mexico), Medicare does not cover health care received abroad. If you travel internationally, a separate travel medical insurance policy is worth considering.

Cosmetic and Experimental Procedures

Cosmetic surgery, experimental treatments not approved by Medicare, and most alternative medicine therapies are excluded from coverage.

How to Fill the Gaps: Your Main Options

Option 1: Medigap (Medicare Supplement Insurance)

Medigap policies are sold by private insurance companies and help cover out-of-pocket costs from Original Medicare, including deductibles, copayments, and coinsurance. There are 10 standardized plan types, labeled A through N. Plans F and G tend to be the most comprehensive. In Oklahoma, you have a guaranteed right to buy any Medigap plan sold in your area during the six-month window that starts the month you turn 65 and are enrolled in Part B. After that window, insurers can deny coverage or charge higher rates based on health status.

Important: Medigap policies do not cover dental, vision, hearing, or long-term care. They fill cost-sharing gaps, not coverage gaps.

Option 2: Medicare Advantage (Part C)

Medicare Advantage plans replace Original Medicare with a bundled plan run by a private insurer. Many Advantage plans include dental, vision, hearing, and wellness benefits that Original Medicare lacks. Some plans in the Oklahoma City metro area offer $0 monthly premiums beyond your Part B premium. However, Advantage plans use provider networks. If you see specialists across the state or travel frequently, check whether your doctors and hospitals are in network before enrolling.

Option 3: Standalone Dental, Vision, and Hearing Plans

If you stay on Original Medicare and a Medigap plan, you can buy separate dental and vision insurance. Many insurers offer individual plans in Oklahoma, with monthly premiums typically ranging from $20 to $60 for dental and $10 to $25 for vision. These plans often have annual benefit caps (commonly $1,000 to $1,500 for dental), so they help with routine care but may not cover major procedures fully.

Option 4: Long-Term Care Planning

Because Medicare does not cover custodial care, planning ahead is critical. Your options include:

• Long-term care insurance: Ideally purchased in your 50s or early 60s when premiums are lower and health conditions are less likely to disqualify you.
• Medicaid (SoonerCare in Oklahoma): Covers nursing facility care for those who meet strict income and asset requirements. Oklahoma also participates in the Medicaid ADvantage waiver program, which provides home and community-based services as an alternative to nursing home placement.
• Veterans' benefits: The VA's Aid and Attendance pension benefit can help eligible veterans and surviving spouses pay for long-term care.
• Personal savings and family planning: Many families combine personal resources with available programs. A conversation with a financial planner experienced in elder care can clarify your options.

Medicare Part D: Prescription Drug Coverage

Original Medicare does not include prescription drug coverage. You need a separate Part D plan or a Medicare Advantage plan that includes drug coverage. Each Part D plan has its own formulary (list of covered drugs), so check that your specific medications are covered before choosing a plan. If you delay enrolling in Part D and do not have other creditable drug coverage, you may face a late enrollment penalty that increases your premiums permanently.

Free Help Is Available in Oklahoma

Sorting through these options does not have to be overwhelming, and you do not have to pay anyone to help. Oklahoma's State Health Insurance Assistance Program (SHIP), operated through the Oklahoma Insurance Department, provides free, one-on-one Medicare counseling. Trained counselors can help you compare plans, understand your benefits, and resolve billing issues. You can reach Oklahoma SHIP by calling the Oklahoma Insurance Department or by contacting the national Eldercare Locator at 1-800-677-1116. You can also visit Medicare.gov to use the official Plan Finder tool to compare Medigap, Advantage, and Part D plans available in your ZIP code.

Your local Area Agency on Aging (Areawide Aging Agency in the Oklahoma City region) is another excellent resource for connecting with benefits counseling, caregiver support, and community services.
