Key Takeaways
-
Medicare in 2025 provides robust coverage for hospital and medical services, but it still leaves out many essential needs such as dental, vision, hearing, and long-term custodial care.
-
Understanding what Medicare does and does not cover can help you plan for additional protection through supplemental coverage, savings, or alternative programs.
Medicare’s Foundation: What It Actually Covers
Medicare is a federal health insurance program primarily for people aged 65 and older, and for certain younger individuals with qualifying disabilities or specific health conditions. It is divided into different parts, each structured to provide support for various healthcare services. However, knowing the differences between them is essential for making smart decisions about your healthcare future.
Medicare Part A – Hospital Insurance
Part A generally covers:
-
Inpatient hospital care (semi-private room, meals, and general nursing)
-
Skilled nursing facility care (following a qualifying hospital stay)
-
Hospice care for terminally ill patients
-
Limited home health services
Most individuals do not pay a monthly premium for Part A if they or their spouse paid Medicare taxes for at least 10 years. Despite this, you are responsible for out-of-pocket costs including deductibles and coinsurance. In 2025, the hospital deductible is $1,676 per benefit period.
Skilled nursing facility coverage is limited. After the 20th day of care, daily coinsurance applies, and after the 100th day, coverage ends entirely. That’s why understanding these time frames is critical.
Medicare Part B – Medical Insurance
Part B helps pay for:
-
Doctor visits and outpatient care
-
Preventive screenings like mammograms and colonoscopies
-
Laboratory tests and imaging
-
Outpatient mental health services
-
Durable medical equipment (e.g., wheelchairs, oxygen equipment)
In 2025, the standard monthly premium is $185, with an annual deductible of $257. Once your deductible is met, you usually pay 20% of the Medicare-approved amount for covered services. There is no annual out-of-pocket limit unless you have additional coverage.
Medicare Part D – Prescription Drug Coverage
Part D provides coverage for prescription medications. Each plan is offered by a private company approved by Medicare, and must meet federal standards, though drug lists and pharmacy networks can vary.
As of 2025, Medicare Part D now includes a $2,000 annual cap on out-of-pocket prescription drug costs. This change eliminates the previous “donut hole” coverage gap and offers financial relief to beneficiaries who need expensive medications.
Medicare Advantage – An Alternative Route
Medicare Advantage (Part C) plans are offered by private insurance companies and must cover all services provided by Parts A and B. Most plans also include Part D coverage, and may offer extra benefits such as routine dental, vision, and hearing. However, coverage rules, provider networks, and cost-sharing vary widely by plan.
Important Services Medicare Still Doesn’t Fully Cover
Despite the broad scope of Medicare, there are important areas it either excludes completely or covers only in limited circumstances. This can leave you facing major costs if you don’t plan ahead.
1. Long-Term Custodial Care
Custodial care—help with daily living activities like dressing, bathing, and eating—is not covered by Medicare. This applies whether it’s provided in a nursing home, assisted living facility, or at home. Medicare will only cover skilled nursing care temporarily following a hospital stay that meets specific criteria.
For example, you must have a minimum 3-day inpatient hospital stay, and the care must be medically necessary. Even then, coverage lasts up to 100 days, with coinsurance starting after 20 days and full responsibility after day 100.
2. Dental Services
Medicare does not pay for routine dental care. This includes cleanings, X-rays, fillings, crowns, bridges, dentures, and tooth extractions. Coverage is only provided in rare circumstances if dental work is needed in conjunction with another Medicare-covered procedure.
3. Vision Care
Routine eye exams, prescription eyeglasses, and contact lenses are excluded. Medicare may cover specific eye-related services like treatment for macular degeneration, cataract surgery (including a basic pair of intraocular lenses), and glaucoma screenings—but not routine vision support.
4. Hearing Aids and Related Exams
Although hearing loss is common among seniors, Medicare does not cover hearing aids or exams for fitting them. Diagnostic hearing and balance exams are only covered when ordered by a doctor to determine treatment.
5. Emergency Care Abroad
Medicare typically does not pay for medical services received outside the United States. Exceptions are rare and limited to specific circumstances, such as when a foreign hospital is closer than a U.S. facility for a medical emergency.
What You Might Think Is Covered—but Isn’t Fully
Some services seem like they should be covered but come with caveats, conditions, or partial reimbursements.
1. Ambulance Services
Emergency ambulance transportation is covered when it is medically necessary and no safer alternatives exist. However, non-emergency transportation (like scheduled visits to dialysis) often isn’t covered unless specific requirements are met.
2. Home Health Services
While Medicare can cover some home health care services, you must meet strict eligibility rules: being homebound, under a doctor’s care, and receiving only part-time or intermittent skilled care. Custodial home care (e.g., cooking, bathing assistance) is not included.
3. Mental Health Services
Medicare covers mental health treatment, but coverage is limited. Inpatient care is capped at 190 days in a psychiatric hospital across your lifetime. Outpatient therapy is covered, but subject to coinsurance and deductibles.
4. Prescription Drugs During Inpatient Care
If you’re hospitalized and bring your own medications, Medicare might not cover them unless the facility’s pharmacy provides the same drug. This can lead to unexpected charges.
Common Misunderstandings That Cost You
Misunderstanding Medicare’s limitations can lead to significant out-of-pocket expenses and missed opportunities to protect your health and finances.
Preventive Services Aren’t Always Free
Although Medicare covers a wide array of preventive services, not all are free. Some require coinsurance or copayments, especially when a diagnostic test is performed during the same visit.
No Out-of-Pocket Maximum on Original Medicare
Original Medicare (Parts A and B) does not include an annual cap on your healthcare spending. If you experience frequent or intensive care needs, costs can accumulate quickly. This is why many beneficiaries add supplemental coverage.
Planning Around the Gaps
Awareness of Medicare’s coverage gaps is your first step. Planning around them ensures your health doesn’t suffer and your savings don’t disappear.
Consider Medigap
Medigap policies, sold by private companies, help cover deductibles, coinsurance, and copayments. There are multiple standardized plan types, each offering a different level of coverage. You must be enrolled in Parts A and B to be eligible.
You have a guaranteed issue right during your 6-month Medigap Open Enrollment Period starting when you’re both 65 and enrolled in Part B. During this time, insurers can’t deny coverage or charge more for preexisting conditions.
Prepare for Uncovered Essentials
Set aside funds to pay for routine dental care, vision exams, eyeglasses, hearing tests, and hearing aids. Even if you’re healthy now, age-related needs tend to increase over time.
Leverage Tax-Advantaged Accounts Before Medicare
While working, take advantage of Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) to build a reserve for future uncovered medical costs. You can no longer contribute to an HSA once enrolled in Medicare, but your funds remain available for eligible expenses.
Stay Ahead of Enrollment Timelines
Key timelines include:
-
Initial Enrollment Period (IEP): Begins 3 months before your 65th birthday, includes your birth month, and ends 3 months after.
-
General Enrollment Period (GEP): January 1 to March 31 annually for those who missed their IEP.
-
Annual Enrollment Period (AEP): October 15 to December 7 to review and change coverage.
-
Medigap Open Enrollment: Lasts 6 months starting from the first month you have both Part B and are age 65 or older.
Missing these windows can lead to late penalties and gaps in coverage.
Avoid Late Enrollment Penalties
Permanent penalties apply if you delay enrollment in Part B or Part D without creditable coverage. These penalties increase the longer you wait and apply for as long as you have Medicare.
What to Do If You’re Already Enrolled
Even if you’ve been enrolled for years, Medicare is not a set-it-and-forget-it program. Plans and costs change yearly, and your health needs may shift as well.
During the Annual Enrollment Period, you can:
-
Switch between Original Medicare and Medicare Advantage
-
Enroll in or change Part D prescription drug plans
-
Drop coverage you no longer use
-
Review changes in your Annual Notice of Change (ANOC) and compare available options
When Coverage Isn’t Enough, Know Your Backup Options
Some healthcare needs remain uncovered. You may qualify for programs that provide additional support if your resources are limited or your needs are greater than Medicare allows.
Medicaid for Dual-Eligible Individuals
If you have low income and limited assets, Medicaid may help pay for premiums, deductibles, and services Medicare doesn’t cover—especially long-term care and certain dental or vision services.
Programs of All-Inclusive Care for the Elderly (PACE)
PACE is designed for older adults who require a nursing-home level of care but want to remain at home. It integrates Medicare and Medicaid benefits, offering comprehensive medical and social services.
State Pharmaceutical Assistance Programs (SPAPs)
SPAPs exist in some states to help residents afford their prescription medications, supplementing Medicare Part D coverage. Each program has its own rules and benefits.
Veterans Affairs (VA) Benefits
If you qualify, VA health benefits can supplement Medicare by providing services like vision, dental, and long-term care—areas where Medicare is limited or silent.
Filling in the Gaps Makes the Biggest Difference
In 2025, Medicare continues to serve as a critical foundation for your healthcare. But it doesn’t cover every need—and often leaves you exposed to high costs for essential services. Understanding these gaps gives you the tools to protect your health and your finances.
Review your plan options annually, explore supplemental coverage, and set aside funds or find programs that help fill in what Medicare leaves out.
