Medicare Coverage: Your Guide to Benefits and Services

Medicare provides health insurance coverage for millions of Americans aged 65 and older, as well as certain younger individuals with disabilities. Understanding what Medicare covers is essential for making informed healthcare decisions and managing medical expenses effectively.

The Four Parts of Medicare Coverage

Medicare is divided into four distinct parts, each covering different aspects of healthcare. Part A covers hospital insurance, including inpatient care, skilled nursing facility care, hospice, and some home health services. Most beneficiaries don't pay a premium for Part A if they or their spouse paid Medicare taxes while working.

Medicare Part B covers medical insurance for doctor services, outpatient care, preventive services, and some home health services. Unlike Part A, Part B requires a monthly premium that's typically deducted from Social Security benefits.

Part C, also known as Medicare Advantage, offers an alternative way to receive Medicare benefits through private insurance companies that contract with Medicare. These plans must provide all Part A and B benefits, and many include prescription drug coverage and additional benefits like vision and dental care.

Part D provides prescription drug coverage through private insurance companies approved by Medicare. These plans help cover the cost of prescription medications, which can be significant for many seniors and individuals with chronic conditions.

Hospital and Medical Services Coverage

Medicare Part A covers essential hospital services when you're formally admitted as an inpatient. This includes semi-private rooms, meals, general nursing, drugs administered during your hospital stay, and other hospital services and supplies. Coverage also extends to critical access hospitals and inpatient care as part of a qualifying clinical research study.

For skilled nursing facility care to be covered, you must meet specific requirements, including a qualifying hospital stay of at least three consecutive days. Medicare then covers up to 100 days in a skilled nursing facility, with a $0 coinsurance for days 1-20 and a daily coinsurance for days 21-100.

Part B covers medically necessary services needed to diagnose or treat medical conditions and preventive services. This includes doctor visits, outpatient care, ambulance services, durable medical equipment, mental health services, and some preventive screenings and vaccinations. Most preventive services are covered at 100% if your provider accepts assignment, meaning they agree to accept the Medicare-approved amount as full payment.

Medicare Provider Comparison

When selecting Medicare coverage, it's important to compare providers to find the best fit for your healthcare needs. Original Medicare (Parts A and B) is managed by the federal government, while Medicare Advantage plans and Part D plans are offered by private insurance companies.

Below is a comparison of major Medicare providers and their offerings:

Provider	Plan Types	Special Features	Network Restrictions
Aetna	Medicare Advantage, Part D	$0 premium plans available, telehealth services	HMO and PPO options
Humana	Medicare Advantage, Part D	SilverSneakers fitness program, mail-order pharmacy	Various network options
UnitedHealthcare	Medicare Advantage, Part D, Supplement	AARP partnership, extensive provider network	HMO, PPO, and PFFS plans
Cigna	Medicare Advantage, Part D	Wellness programs, 24/7 nurse line	Varies by location

When comparing providers, consider factors such as premium costs, deductibles, copayments, provider networks, drug formularies, and additional benefits. Medicare.gov offers a plan finder tool that allows you to compare plans based on your specific medications and preferences.

What Medicare Doesn't Cover

While Medicare provides comprehensive coverage for many healthcare needs, there are significant services that it doesn't cover. Understanding these gaps is crucial for planning your healthcare budget and considering supplemental insurance options.

Long-term care (also called custodial care) is perhaps the most significant gap in Medicare coverage. This includes assistance with daily activities like bathing, dressing, and eating when that's the only care you need. Medicare does not cover care in an assisted living facility when custodial care is the only care needed.

Most dental care including cleanings, fillings, tooth extractions, dentures, and other dental devices aren't covered by Medicare. Similarly, routine vision care such as eye exams for prescribing glasses and the glasses themselves aren't covered. Hearing aids and exams for fitting hearing aids are also excluded from Medicare coverage.

Other notable exclusions include cosmetic surgery, routine foot care, acupuncture (with limited exceptions for chronic low back pain), and healthcare received while traveling outside the United States (with very limited exceptions). Additionally, Medicare does not cover alternative medicine treatments like homeopathy or naturopathy.

Supplemental Coverage Options

To address the gaps in Medicare coverage, many beneficiaries choose to purchase supplemental insurance. Medicare Supplement Insurance (Medigap) policies are sold by private companies and can help pay for some of the healthcare costs that Original Medicare doesn't cover, such as copayments, coinsurance, and deductibles.

There are 10 standardized Medigap plans available in most states, each labeled with a letter (A, B, C, D, F, G, K, L, M, and N). Each plan offers a different combination of benefits, allowing you to choose the coverage that best meets your needs and budget. Plans with more comprehensive coverage typically have higher premiums.

Another option is enrolling in a Medicare Advantage plan, which often includes additional benefits not covered by Original Medicare, such as dental, vision, and hearing care. Some Medicare Advantage plans also offer coverage for services like transportation to doctor visits, over-the-counter drugs, and adult day-care services.

For prescription drug coverage, you can enroll in a Part D plan or choose a Medicare Advantage plan that includes prescription drug coverage. It's important to review the plan's formulary (list of covered drugs) to ensure your medications are covered.

Conclusion

Navigating Medicare coverage requires understanding the various parts, benefits, limitations, and supplemental options available. By familiarizing yourself with what Medicare does and doesn't cover, you can make informed decisions about your healthcare coverage and avoid unexpected costs. Remember that Medicare coverage and options change annually, so it's advisable to review your coverage during the Annual Enrollment Period (October 15 to December 7) to ensure it still meets your healthcare needs. For personalized assistance, consider consulting with a Medicare counselor through your State Health Insurance Assistance Program (SHIP) or using the tools available on Medicare.gov.
