Understanding Medicare: Breaking Down the ABC’s and D of Coverage

May 15, 20254 min read

Navigating Medicare can sometimes feel like learning a new language. With its different parts and coverage options, it’s easy to get overwhelmed. Whether you're approaching eligibility or helping a loved one, understanding Medicare’s components is the first step to making informed decisions. Let’s simplify Medicare by breaking down the essentials of Parts A, B, C, and D—and we’ll touch on key updates coming in 2025.

Part A: Hospital Insurance

Medicare Part A is often referred to as hospital insurance because it covers inpatient hospital stays, skilled nursing facilities, hospice care, and some home health care services. Most people don’t pay a premium for Part A if they or their spouse have worked and paid Medicare taxes for at least ten years. However, there are some costs to be aware of:

Key Costs in 2025:

- Deductible: Beneficiaries will face an inpatient hospital deductible of $1,600 for each benefit period.

- Coinsurance: After 60 days in the hospital, you'll pay $400 per day in coinsurance, which increases to $800 per day after 90 days.

Part A provides essential coverage but doesn’t pay for long-term care, so planning for additional coverage is crucial if extended stays or specialized care are anticipated.

Part B: Medical Insurance

Medicare Part B covers outpatient care, doctor visits, preventive services, and medical supplies. Unlike Part A, nearly all beneficiaries pay a monthly premium. For 2025, the standard premium is expected to rise slightly to $180.90 per month, with higher-income earners paying more based on income brackets.

Coverage Highlights:

- Preventive Services: Annual wellness visits, vaccinations, and screenings for conditions like cancer and diabetes.

- Medically Necessary Services: Diagnostic tests, outpatient surgeries, and durable medical equipment (DME) like wheelchairs or walkers.

Costs to Note:

- Deductible: The annual deductible for Part B will be $240 in 2025.

- Coinsurance: After meeting the deductible, beneficiaries typically pay 20% of the Medicare-approved amount for most Part B services.

Part C: Medicare Advantage

Medicare Advantage, also known as Part C, combines Parts A and B into a single plan offered by private insurance companies. Many plans also include Part D (prescription drug coverage) and additional benefits like dental, vision, and hearing care.

Why Choose Medicare Advantage?

- Comprehensive Coverage: One plan for medical, hospital, and often prescription coverage.

- Cost Predictability: Many plans have lower out-of-pocket maximums compared to Original Medicare.

- Extra Perks: Some plans offer wellness programs, transportation, and gym memberships.

Updates for 2025:

CMS has announced increased funding for Medicare Advantage plans in 2025, which could lead to more robust benefits and reduced premiums in certain areas. Additionally, plans will now be required to offer more detailed explanations of their networks and costs, ensuring greater transparency for beneficiaries.

Part D: Prescription Drug Coverage

Part D helps cover the cost of prescription drugs. It’s offered through private insurers and can be added to Original Medicare or included in many Medicare Advantage plans.

How It Works:

- Formulary: Each plan has a list of covered drugs, categorized by tiers. Lower-tier drugs are typically generic and cost less, while higher-tier drugs are brand-name or specialty medications.

- Phases of Coverage: Beneficiaries move through different cost phases, including the deductible, initial coverage, coverage gap (donut hole), and catastrophic coverage.

Changes in 2025:

The Inflation Reduction Act introduces major reforms to Part D:

- Out-of-Pocket Cap: Beneficiaries’ annual out-of-pocket costs for prescription drugs will be capped at $2,000 starting in 2025.

- Expanded Low-Income Subsidy (LIS): More beneficiaries will qualify for assistance with premiums and copayments, reducing their drug costs.

- Insulin Price Caps: Insulin copayments will remain capped at $35 per month, benefiting millions of Americans managing diabetes.

What About Medigap?

Medigap, or Medicare Supplement Insurance, isn’t a part of Medicare but plays a crucial role for those enrolled in Original Medicare. These policies help cover out-of-pocket costs like deductibles, copayments, and coinsurance. While Medigap doesn’t include drug coverage, pairing it with a Part D plan provides comprehensive protection.

Choosing the Right Coverage

Medicare is not one-size-fits-all. Your choice depends on:

- Health Needs: Chronic conditions or frequent prescriptions might make Part D or a comprehensive Medicare Advantage plan more appealing.

- Budget: Balancing premiums, deductibles, and out-of-pocket costs.

- Preferred Providers: Original Medicare allows nationwide access, while Medicare Advantage plans often require staying within a network.
