Medicare has four parts designed to provide essential coverage for eligible individuals. Part A covers hospital care, while Part B supports doctor visits and other outpatient services. Medicare Advantage (Part C) offers an alternative way to receive benefits by combining Parts A, B, and sometimes D into one plan, often including extra benefits. Part D provides prescription drug coverage.

In addition to these core parts, many people enhance their coverage with supplemental insurance, commonly known as Medigap or Medicare Supplements. These policies help cover costs that original Medicare may not fully address, easing out-of-pocket expenses. Whether you choose to pair original Medicare with Medigap or select a Medicare Advantage plan, the options available are designed to meet diverse health needs and budgets, making essential healthcare services more accessible and supporting overall well-being.

The Four Parts of Medicare + Medigap

Part A and Part B - Original Medicare

Medicare Parts A and B, known as Original Medicare, provide essential healthcare coverage for eligible individuals. Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and select home health services. Many qualify for premium-free Part A based on work history.

Part B covers doctor visits, outpatient care, preventive services, and necessary medical supplies, though it requires a monthly premium and may include deductibles and coinsurance. Original Medicare offers access to a broad network of doctors and specialists.

Many opt to add Medicare Supplement (Medigap) insurance or enroll in Medicare Part D for extra prescription drug coverage.

Medigap / Medicare Supplement Plans

Medicare Supplement Insurance plans, also known as Medigap plans, help cover out-of-pocket costs like deductibles, copayments, and coinsurance that Original Medicare (Part A & Part B) doesn’t pay. These plans are offered by private insurance companies and allow you to see any doctor or hospital that accepts Medicare nationwide.

Medigap plans work alongside Original Medicare, but they do not include prescription drug coverage. This additional coverage offers a more predictable financial experience by reducing unexpected out-of-pocket costs, but still leaves two large Medicare exposures open.

Choosing the right plan depends on your healthcare needs and budget.

Part C - Medicare Advantage Plans

Medicare Advantage Plans, also known as Part C, are offered by private insurance companies approved by Medicare. These plans provide all the benefits of Original Medicare (Parts A & B) and often include additional coverage such as prescription drugs, dental, vision, and hearing services.

Medicare Advantage plans are US county-dependent and costs and benefits can vary between locations across the USA. Part C plans have different costs, coverage options, and provider networks, so it’s important to review your choices to find a plan that fits your needs with availability in your zip code and county.

Part D - Medicare Prescription Drug Plans

Medicare Part D helps cover the cost of prescription medications and is available through private insurance companies approved by Medicare. These plans work alongside Original Medicare or can be added with a Medicare Supplement plan to provide a comprehensive coverage package.

Each Part D plan has a list of covered drugs (formulary) and may have different premiums, copayments, and pharmacy networks. Similar to Medicare Advantage plans, Medicare Part D plans are US county-specific. It’s important to review your options to ensure your medications are covered at the best cost.

Key Exposures of Medicare

Medicare includes certain gaps in coverage about which beneficiaries should be aware. For example, although Medicare Part A covers skilled nursing facility care for up to 100 days, Original Medicare (Part A or Part B),  Medigap, and Medicare Advantage do not cover costs incurred after day 101.

In addition, Medicare does not provide coverage for long-term custodial care or extended support services, which may result in significant out-of-pocket expenses when long-term assistance becomes necessary.

Another key exposure involves high-tiered prescription drugs under Medicare Part D. Beneficiaries might encounter substantial deductibles for expensive medications, particularly those prescribed following major health events such as a heart attack or stroke, or for experimental drugs and procedures associated with specific diagnoses.

Frequently asked questions - Medicare

Medicare enrollment tips suggest that the Initial Enrollment Period is optimal. This 7-month window—beginning 3 months before your 65th birthday and ending 3 months after—ensures continuous coverage, avoids gaps, and prevents increased costs later. Timely enrollment is key to accessing Medicare coverage options.

Medicare Part A is usually premium-free for those with sufficient work credits, while Parts B, C (Medicare Advantage), and D typically require monthly premiums. Part B covers outpatient services and preventive care; Part C bundles benefits, and Part D helps with prescription drugs. Understanding these costs is essential when reviewing Medicare coverage options.

To steer clear of Medicare late enrollment penalties, sign up during your Initial Enrollment Period. Delays may result in higher monthly premiums and coverage gaps. Knowing the eligibility criteria and enrollment deadlines is crucial for a smooth transition to Medicare, ensuring that your healthcare coverage starts without interruption or added costs.

Missing the Medicare Initial Enrollment Period can lead to a coverage gap and the imposition of late enrollment penalties. Without timely sign-up, you may have to wait for the General Enrollment Period, delaying your benefits. This delay can result in permanently higher premiums and increased financial risk when unexpected medical expenses occur.

For those still employed at 65, continuing employer-provided health coverage may allow a delay in Medicare enrollment without penalty. The coordination between employer benefits and Medicare depends on the employer’s size and plan details. Evaluating your current coverage against Medicare coverage options can help determine the best time to enroll.
