Understanding the Limitations of Medicare Part B
While Medicare Part B provides crucial coverage for a wide range of outpatient services, it is far from comprehensive. Many common healthcare needs are excluded, and assuming coverage without confirmation can lead to significant financial surprises. Knowing these exclusions is the first step toward securing the right supplemental plans, such as Medicare Advantage or Medigap, to protect your finances and your health.
The Major Exclusions: Routine Dental, Vision, and Hearing
Many beneficiaries are shocked to learn that Original Medicare provides virtually no coverage for routine dental, vision, and hearing services, which become increasingly important with age.
Routine Dental Care
- Dental exams, cleanings, and X-rays: These standard preventive services are not covered.
- Dentures, fillings, and tooth extractions: Major dental procedures are also typically excluded.
- Limited exceptions: Medicare will cover certain dental services that are deemed medically necessary as part of a larger covered treatment, such as a dental exam before a heart valve replacement or organ transplant.
Vision Services
- Routine eye exams: Original Medicare does not cover annual checkups for prescription eyeglasses.
- Eyeglasses and contact lenses: The cost of new or updated prescription lenses is the beneficiary's responsibility.
- Exceptions: Medicare Part B does cover medically necessary eye exams and treatments for specific conditions like cataracts, glaucoma, and diabetic retinopathy. It also covers one set of corrective lenses after cataract surgery with an intraocular lens implant.
Hearing Services
- Routine hearing tests: Standard hearing screenings are not covered.
- Hearing aids and fittings: The costs associated with hearing aids, a significant expense, are not covered by Part B.
- Exceptions: Part B may cover some diagnostic hearing and balance exams if a doctor determines they are necessary to treat an illness or injury.
Other Notable Exclusions from Part B
Beyond routine care, several other services and items are explicitly excluded from Part B coverage:
- Long-Term (Custodial) Care: This is one of the most significant coverage gaps. Part B does not pay for non-skilled, personal care, such as assistance with daily living activities (bathing, dressing, eating) in a nursing home or at home. It covers medically necessary skilled care for a limited period, but not the long-term custodial care many seniors require.
- Most Prescription Drugs: The majority of outpatient prescription medications are covered under Medicare Part D, a separate, optional plan. Part B only covers a select number of drugs, typically those that are administered by a medical professional in a doctor's office or outpatient setting, like injections and infusions.
- Cosmetic Surgery: Procedures performed solely to improve appearance, such as facelifts, liposuction, or breast augmentation, are not covered. However, reconstructive surgery following an injury or to correct a congenital defect may be covered if deemed medically necessary.
- Routine Physical Exams: While Part B covers an initial "Welcome to Medicare" preventative visit and subsequent annual wellness visits, it does not cover a comprehensive, routine physical exam.
- Routine Foot Care: Clipping, trimming, or removing calluses from feet is generally not covered, though medically necessary foot care related to certain conditions like diabetes is covered.
A Quick Comparison: Part B Covered vs. Excluded Services
| Service Category | Covered by Part B? | Excluded from Part B? |
|---|---|---|
| General Medical Services | Yes (Doctors' visits, diagnostics) | Routine physical exams (except the Annual Wellness Visit) |
| Dental Care | Yes (Medically necessary) | Routine cleanings, fillings, dentures |
| Vision Services | Yes (Medically necessary) | Routine eye exams, eyeglasses, contacts (except post-cataract) |
| Hearing Services | Yes (Diagnostic exams) | Hearing aids, hearing aid fittings |
| Prescription Drugs | Yes (Administered in-office) | Most self-administered outpatient drugs (Part D coverage) |
| Long-Term Care | Yes (Skilled care) | Custodial care for daily living needs |
| Elective Procedures | Yes (Reconstructive surgery) | Cosmetic surgery for appearance |
Exploring Alternatives for Uncovered Costs
Since Medicare Part B leaves significant gaps, beneficiaries have options to fill them:
- Medicare Advantage (Part C) Plans: These plans, offered by private insurers, must provide all Part A and Part B coverage and often include additional benefits like dental, vision, and hearing coverage.
- Medicare Supplement (Medigap) Plans: These plans are sold by private companies and help pay some of the costs that Original Medicare doesn't, such as copayments, coinsurance, and deductibles.
- Stand-Alone Dental or Vision Insurance: For those with Original Medicare, purchasing separate insurance policies can help cover routine and major dental or vision costs.
- Health Savings Accounts (HSAs): If eligible, HSAs can be used to save for and pay for qualified medical expenses tax-free.

Conclusion: Strategic Planning Is Key
Knowing what does part B of Medicare not cover? is critical for any beneficiary. By understanding the program's limitations regarding dental, vision, hearing, long-term care, and prescription drugs, you can proactively explore supplemental options. Strategic planning allows you to create a comprehensive healthcare picture that minimizes out-of-pocket expenses and ensures you receive the full scope of care you need for a healthy and secure retirement.
