Understanding the Gaps in Original Medicare Coverage
Original Medicare, which includes Part A (hospital insurance) and Part B (medical insurance), provides robust coverage for a wide array of medically necessary services and supplies. However, it was never designed to be all-encompassing, leaving significant gaps that can lead to substantial out-of-pocket costs for beneficiaries. Navigating these limitations is a critical part of healthy aging, as these uncovered services often become more relevant with age.
Dental Care
One of the most common and costly exclusions in Original Medicare is routine dental care.
This means that many necessary services are not covered, forcing beneficiaries to pay for them entirely out of pocket. These typically include:
- Routine cleanings and check-ups
- Fillings and tooth extractions
- Root canals and crowns
- Dentures and dental plates
Original Medicare will only cover dental services under very specific, medically necessary circumstances, such as a dental procedure required for a more significant medical treatment like an organ transplant or heart valve replacement. For comprehensive dental coverage, beneficiaries must look at separate dental insurance plans or specific Medicare Advantage plans that include dental benefits.
Vision Care
Another major gap is coverage for routine vision services. The program focuses on medical conditions of the eye but excludes everyday needs.
Services generally not covered by Parts A or B include:
- Routine eye exams for prescribing glasses or contact lenses
- Eyeglasses and contact lenses themselves
Exceptions exist for medical issues, such as cataract surgery or treatments for glaucoma. Many seniors address this gap by enrolling in a Medicare Advantage plan that includes vision benefits or by purchasing a separate vision insurance plan.
Hearing Aids
Similar to dental and vision, Original Medicare offers almost no coverage for hearing aids or the associated services.
Here's what is typically excluded:
- Routine hearing exams to check for hearing loss
- Hearing aids and their fitting
While Original Medicare may cover a diagnostic hearing exam if a physician orders it to determine if medical treatment is needed, it does not pay for the aids themselves. This is a crucial exclusion, as hearing aids can be expensive and hearing loss is a common issue for older adults. Medicare Advantage plans are a popular alternative, with many offering coverage for hearing aids and related services.
Long-Term Care
This can be one of the most financially devastating coverage gaps for seniors. Long-term care, also known as custodial care, is assistance with daily living activities such as bathing, dressing, and eating. Original Medicare explicitly excludes coverage for long-term care in assisted living facilities or at home.
- Original Medicare does cover: Medically necessary skilled nursing facility (SNF) care for a limited time following a qualifying hospital stay.
- Original Medicare does not cover: The vast majority of care in nursing homes or assisted living facilities, which is custodial in nature.
Planning for long-term care costs requires looking at options like long-term care insurance, Medicaid (for those who qualify), or using personal savings.
Prescription Drugs
Perhaps the most well-known gap in Original Medicare is the lack of coverage for most outpatient prescription drugs.
- Original Medicare Part A and B cover some drugs, primarily those administered in a hospital or doctor's office (e.g., chemotherapy drugs). However, it does not cover prescriptions filled at a pharmacy.
To address this, beneficiaries can enroll in a stand-alone Medicare Part D prescription drug plan or choose a Medicare Advantage plan (Part C) that includes drug coverage. Failing to secure Part D coverage when first eligible can result in a late enrollment penalty.
Comparison of Original Medicare and Medicare Advantage
Understanding the differences between these two options can be key to filling the coverage gaps.
| Feature | Original Medicare (Parts A & B) | Medicare Advantage (Part C) |
|---|---|---|
| Network | Nationally accepted by most providers | Varies by plan; often an HMO or PPO network |
| Referrals | Generally not required | Often required for specialists |
| Prescription Drugs | Not covered (requires separate Part D plan) | Most plans include Part D coverage |
| Dental/Vision/Hearing | Not covered (requires separate plans) | Many plans offer some coverage |
| Out-of-Pocket Max | No annual maximum | Annual out-of-pocket maximum |
| Extra Benefits | None | May include fitness memberships and transportation |
Care Outside the United States
Travelers should be aware that Original Medicare provides very limited coverage for medical care received while traveling outside the United States. In most cases, it does not cover health services received abroad.
- Exceptions: Limited emergency care may be covered in a few specific situations, such as on a ship within U.S. territorial waters. However, these are rare exceptions, not the rule.
For those who travel frequently, Medigap (Medicare Supplement Insurance) policies can offer foreign travel emergency care coverage. Alternatively, travel health insurance is another option for coverage outside the U.S.
Other Excluded Services
Beyond the major areas, other services are typically not covered by Original Medicare, such as:
- Cosmetic surgery: Unless medically necessary, such as breast reconstruction after a mastectomy.
- Routine foot care: Covered only if a medical condition affecting the lower extremities requires treatment by a podiatrist.
- Concierge care: Also known as retainer-based medicine, where a doctor charges a special fee for extra services.
- Acupuncture and alternative treatments: Limited coverage, if any, for alternative medical treatments.

Making Informed Decisions
Being aware of what Original Medicare does not cover is the first step toward securing more comprehensive healthcare in retirement. While the coverage for hospital and medical expenses is foundational, the exclusions for dental, vision, hearing, prescription drugs, and long-term care require careful planning.
Beneficiaries should review their healthcare needs and budget to determine if a Medicare Advantage plan, a Medigap policy with a Part D plan, or other supplemental insurance options are the right choice. Proactive planning ensures a healthier and more financially secure future.
