5 Key Things You Need to Know About Medicare Parts A, B, C, and D to Make the Best Choice for Your Healthcare Needs

Key Takeaways:

  • Medicare is divided into four parts: A, B, C, and D, each covering different healthcare needs. Understanding these parts can help you make the best choice for your medical care in 2025.

  • Costs, coverage, and enrollment rules vary for each Medicare part, so knowing how they work together is essential for maximizing benefits and minimizing out-of-pocket expenses.

Breaking Down Medicare Part A: Hospital Coverage

Medicare Part A is your hospital insurance, covering inpatient stays, skilled nursing facility care, hospice, and some home healthcare services. If you’ve worked and paid Medicare taxes for at least 10 years, you generally qualify for premium-free Part A. However, if you have fewer than 40 work credits, you may need to pay a monthly premium.

What Does Part A Cover?

  • Hospital Stays: Covers semi-private rooms, meals, general nursing, and hospital services.

  • Skilled Nursing Facility (SNF) Care: Covers rehabilitation and therapy services after a hospital stay of at least three days.

  • Hospice Care: Available for terminally ill patients with a life expectancy of six months or less.

  • Limited Home Healthcare: Covers intermittent skilled nursing care and therapy services if deemed medically necessary.

Costs and Coverage Limits in 2025

  • Inpatient Hospital Deductible: $1,676 per benefit period.

  • Coinsurance for Hospital Stays:

    • Days 1-60: No coinsurance after deductible.

    • Days 61-90: $419 per day.

    • Beyond 90 days: $838 per lifetime reserve day (up to 60 days over your lifetime).

  • Skilled Nursing Facility Coinsurance:

    • First 20 days: $0 per day.

    • Days 21-100: $209.50 per day.

Medicare Part B: Medical Insurance for Outpatient Services

Part B covers medically necessary services like doctor visits, preventive care, outpatient hospital services, and durable medical equipment. Unlike Part A, you must pay a monthly premium to keep Part B coverage active.

What’s Covered Under Part B?

  • Doctor Visits: Includes routine check-ups and specialist appointments.

  • Preventive Care: Annual wellness visits, screenings, and vaccinations.

  • Outpatient Procedures: Surgeries, diagnostic tests, and imaging services.

  • Mental Health Services: Covers therapy, counseling, and psychiatric care.

  • Durable Medical Equipment (DME): Walkers, wheelchairs, and home oxygen therapy.

Costs and Premiums in 2025

  • Standard Monthly Premium: $185.

  • Annual Deductible: $257.

  • Coinsurance: Typically 20% of the Medicare-approved amount for services after meeting the deductible.

Medicare Part C: The All-in-One Alternative

Medicare Part C, also known as Medicare Advantage, is an alternative to Original Medicare (Parts A and B). These plans are offered by private insurance companies and may include additional benefits like dental, vision, and hearing coverage.

What Do Medicare Advantage Plans Cover?

  • Everything Original Medicare Covers: Must include the same coverage as Parts A and B.

  • Additional Benefits: May include fitness programs, transportation, and over-the-counter allowances.

  • Prescription Drug Coverage: Many plans bundle Part D into their benefits.

Important Considerations

  • Network Restrictions: Most plans require you to use in-network doctors and hospitals.

  • Annual Out-of-Pocket Maximum: In 2025, the in-network MOOP is $9,350, while combined in-network and out-of-network MOOP is $14,000.

Medicare Part D: Prescription Drug Coverage

Part D helps cover the cost of prescription medications. Plans are offered by private insurers, and coverage varies by plan.

What’s Included in Part D Coverage?

  • Formulary Tiers: Medications are categorized into different pricing levels.

  • Catastrophic Coverage: Once you reach $2,000 in out-of-pocket drug costs, your plan covers 100% of covered prescriptions for the rest of the year.

  • Medicare Prescription Payment Plan: In 2025, beneficiaries can opt to spread their out-of-pocket costs throughout the year instead of paying high costs upfront.

Costs and Deductibles in 2025

  • Maximum Deductible: $590.

  • Copayments and Coinsurance: Varies based on the plan’s drug formulary.

Choosing the Right Medicare Plan for Your Needs

With four different Medicare parts, selecting the right coverage can feel overwhelming. Here are five essential considerations:

1. Assess Your Healthcare Needs

If you require frequent medical care, Part B’s outpatient coverage and a Part D plan for prescriptions may be necessary. Those with minimal medical expenses might prefer Original Medicare alone.

2. Compare Costs

Look at premiums, deductibles, and out-of-pocket maximums. If you’re on a budget, weigh the cost of a Medicare Advantage plan against Original Medicare plus a Medigap plan.

3. Understand Enrollment Periods

  • Initial Enrollment Period (IEP): A 7-month window around your 65th birthday.

  • General Enrollment Period (GEP): January 1 – March 31 each year.

  • Annual Enrollment Period (AEP): October 15 – December 7, when you can switch plans.

4. Check Doctor and Hospital Networks

Original Medicare allows you to see any provider that accepts Medicare, while Medicare Advantage plans typically have provider networks.

5. Consider Supplemental Coverage

Medicare Supplement (Medigap) plans can help cover out-of-pocket costs associated with Original Medicare.

Making an Informed Medicare Decision

Understanding Medicare Parts A, B, C, and D is key to choosing a plan that fits your health needs and budget. Whether you prefer the flexibility of Original Medicare or the bundled benefits of Medicare Advantage, comparing options carefully will help you get the most value from your coverage.
