Medicare is a federal health insurance program primarily for people aged 65 and older. It also covers certain younger individuals with disabilities or specific diseases. Think of it as your healthcare safety net in retirement—a way to help pay for doctor visits, hospital stays, and even prescription drugs.
A Brief History of Medicare
Established in 1965 under President Lyndon B. Johnson, Medicare has transformed the healthcare landscape for older Americans. Before Medicare, nearly half of seniors had no health insurance. Now, over 65 million people rely on it.
Who Qualifies for Medicare?
Age Eligibility
Most people qualify when they turn 65. If you or your spouse worked and paid Medicare taxes for at least 10 years, you’ll likely get Part A free.
Disability and Special Circumstances
Under 65? You may still qualify if you’ve been receiving Social Security Disability Insurance (SSDI) for at least 24 months, or if you have End-Stage Renal Disease (ESRD) or ALS.
Understanding Medicare Parts
Medicare Part A – Hospital Insurance
Covers inpatient care: hospitals, skilled nursing facilities, hospice, and some home healthcare. If you’ve worked long enough, this part is usually premium-free.
Medicare Part B – Medical Insurance
Covers outpatient services: doctor visits, preventive care, lab tests, and medical equipment. You pay a monthly premium, often deducted from Social Security.
Medicare Part C – Medicare Advantage
Offered by private insurers, these plans bundle Parts A, B, and often D. They might include extras like dental or vision. You still enroll in Medicare, but your care is managed by a private plan.
Medicare Part D – Prescription Drug Coverage
Helps cover the cost of medications. You can get it as a standalone plan or included in Medicare Advantage.
How the Parts Work Together
Think of Part A and B as the foundation, Part D as the drug coverage add-on, and Part C as an all-in-one alternative.
What Medicare Covers
Covered Services in Part A
Hospital stays (semi-private rooms)
Hospice care
Skilled nursing facility (short-term)
Limited home healthcare
Covered Services in Part B
Doctor visits
Preventive services (flu shots, cancer screenings)
Mental health services
Durable medical equipment
Additional Benefits with Part C
Many Medicare Advantage plans offer:
Dental
Vision
Hearing aids
Gym memberships
Drug Coverage with Part D
Helps lower your prescription costs and protects against high drug expenses.
What Medicare Does Not Cover
Dental, Vision, Hearing, and More
Original Medicare doesn’t cover routine dental, eye exams, hearing aids, or cosmetic procedures. That’s where Advantage plans or separate insurance come in.
Long-Term Care Limitations
Medicare doesn’t pay for custodial care—help with daily tasks like bathing or dressing. That’s where Medicaid or long-term care insurance may be needed.
Costs and Premiums
Premiums for Each Part
Part A: Usually free
Part B: Standard premium (in 2025, around $175/month)
Part C: Varies by plan
Part D: Varies by plan and income
Deductibles and Co-pays
Expect to pay a deductible for Part A ($1,600+ per benefit period) and Part B ($240+ annually), plus 20% coinsurance for services.
