Navigating the complexities of healthcare can be daunting, especially when it comes to Medicare. Understanding the rules and regulations that govern this vital program is crucial for ensuring you receive the coverage you’re entitled to and avoid potential pitfalls. This guide will break down the key Medicare rules, helping you make informed decisions about your healthcare options.

Understanding Original Medicare (Parts A & B)

Original Medicare, comprised of Part A (hospital insurance) and Part B (medical insurance), forms the foundation of Medicare coverage for many Americans. It’s important to understand what each part covers and the associated costs.

Part A: Hospital Insurance

Part A primarily covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home healthcare services.

• Coverage Details:

Inpatient Hospital Stays: Covers a semi-private room, meals, general nursing, hospital services and supplies.

Example: If you’re admitted to the hospital for pneumonia, Part A covers your room, nursing care, and medications administered during your stay.

Skilled Nursing Facility (SNF) Care: Covers a limited stay in a SNF following a qualifying hospital stay (at least 3 days).

Hospice Care: Provides comfort care and support for individuals with a terminal illness.

Home Healthcare: Covers medically necessary part-time or intermittent skilled nursing care, physical therapy, occupational therapy, speech-language pathology services, home health aide services, and medical social services.

• Cost Considerations:

Most people don’t pay a monthly premium for Part A because they’ve paid Medicare taxes during their working years.

However, there’s a deductible for each benefit period (a benefit period starts the day you’re admitted as an inpatient in a hospital or skilled nursing facility and ends when you haven’t received any inpatient hospital care or skilled nursing facility care for 60 days in a row).

Coinsurance may apply for extended stays in a hospital or SNF.

Actionable Takeaway: Check your Medicare statement or contact Medicare to confirm your Part A eligibility and cost-sharing responsibilities.

Part B: Medical Insurance

Part B covers a wide range of medical services and supplies, including doctor’s visits, outpatient care, preventive services, and some medical equipment.

• Coverage Details:

Doctor’s Services: Covers visits to your primary care physician, specialists, and other healthcare providers.

Outpatient Care: Includes services received in a hospital outpatient department, such as X-rays, lab tests, and surgeries.

Preventive Services: Covers screenings and vaccinations to help prevent illnesses, such as flu shots, mammograms, and colonoscopies.

Durable Medical Equipment (DME): Covers items like wheelchairs, walkers, and oxygen equipment.

Example: Regular checkups with your primary care physician are covered under Part B. Preventative care, such as flu shots, are also covered.

• Cost Considerations:

Most people pay a monthly premium for Part B. The standard premium can change each year. Higher-income individuals may pay a higher premium (Income Related Monthly Adjustment Amount – IRMAA).

There’s an annual deductible that you must meet before Medicare starts paying its share.

Typically, you’ll pay 20% of the Medicare-approved amount for most services after you meet your deductible.

Actionable Takeaway: Review your Medicare Part B premium and deductible amounts each year, as they can change. Consider supplemental insurance to cover the 20% coinsurance.

Medicare Advantage (Part C)

Medicare Advantage plans (Part C) are offered by private insurance companies approved by Medicare. These plans combine Part A and Part B coverage and often include Part D (prescription drug coverage).

Plan Types and Coverage

Medicare Advantage plans come in various forms, each with its own rules and network requirements. Common types include:

• Health Maintenance Organization (HMO): Requires you to choose a primary care physician (PCP) who coordinates your care and refers you to specialists. You typically need to stay within the plan’s network to receive coverage (except in emergencies).
• Preferred Provider Organization (PPO): Allows you to see doctors and specialists both inside and outside the plan’s network, but you’ll generally pay less for in-network care.
• Private Fee-for-Service (PFFS): Allows you to go to any Medicare-approved doctor or hospital that accepts the plan’s terms, but not all providers may accept the plan.
• Special Needs Plans (SNP): Tailored to individuals with specific chronic conditions or those who reside in long-term care facilities.

• Coverage Details:

Medicare Advantage plans must cover everything that Original Medicare covers, but they may offer additional benefits, such as vision, dental, and hearing coverage.

Many Medicare Advantage plans include Part D prescription drug coverage.

• Actionable Takeaway: Carefully compare different Medicare Advantage plans to find one that meets your specific healthcare needs and preferences. Consider the plan’s network, cost-sharing, and extra benefits.

Rules and Regulations

Medicare Advantage plans are subject to specific rules and regulations to protect beneficiaries.

• Enrollment Periods: You can enroll in a Medicare Advantage plan during the Initial Enrollment Period (IEP), Annual Enrollment Period (AEP), or a Special Enrollment Period (SEP).
• Prior Authorization: Many Medicare Advantage plans require prior authorization for certain services, meaning you need to get approval from the plan before receiving the service.

Example: Some Advantage plans may require prior authorization for MRI scans, which can add to the administrative burden for both you and your doctor.

• Appeals and Grievances: You have the right to appeal a plan’s decision if you disagree with it. Plans must have a formal grievance process for addressing complaints.
• Actionable Takeaway: Be aware of the enrollment periods for Medicare Advantage plans and understand the plan’s rules regarding prior authorization and appeals.

Medicare Prescription Drug Coverage (Part D)

Medicare Part D helps cover the cost of prescription drugs. It’s offered through private insurance companies that have been approved by Medicare.

Enrollment and Costs

Enrolling in a Part D plan is generally voluntary, but there are potential penalties for late enrollment.

• Enrollment Periods: Similar to Medicare Advantage, you can enroll in a Part D plan during the IEP, AEP, or a SEP.
• Late Enrollment Penalty: If you don’t enroll in Part D when you’re first eligible and you don’t have creditable prescription drug coverage from another source (like an employer-sponsored plan), you may have to pay a late enrollment penalty.

This penalty is added to your monthly premium for as long as you have Medicare drug coverage.

• Cost Considerations:

Part D plans have monthly premiums, deductibles, and cost-sharing (copayments or coinsurance).

The amount you pay depends on the plan you choose and the medications you take.

Example: Some plans have low monthly premiums but higher deductibles, while others have higher premiums but lower deductibles. Choose a plan that fits your specific needs.

• Actionable Takeaway: Compare different Part D plans to find one that covers your medications at a reasonable cost. Consider the plan’s formulary (list of covered drugs), deductible, and cost-sharing. Don’t delay enrollment if you need prescription drug coverage, to avoid late enrollment penalties.

The Coverage Gap (Donut Hole)

Many Part D plans have a coverage gap, also known as the “donut hole.” This is a temporary limit on what the plan will cover for prescription drugs. This has been phased out, but understanding how it used to work is still important.

• How the Coverage Gap Worked (Historically):

After you and your plan spent a certain amount on covered drugs, you would enter the coverage gap.

While in the coverage gap, you would pay a higher percentage of your drug costs.

• Current Status: The coverage gap has been largely eliminated. Beneficiaries now pay a maximum of 25% of covered prescription drug costs while in this phase of coverage.

Extra Help

If you have limited income and resources, you may be eligible for Extra Help, a program that helps pay for Medicare prescription drug costs.

• Eligibility Requirements: To qualify for Extra Help, you must meet certain income and resource limits.
• Benefits: Extra Help can lower your monthly Part D premium, deductible, and copayments.
• Actionable Takeaway: If you have limited income and resources, apply for Extra Help to reduce your prescription drug costs. Contact the Social Security Administration for more information.

Medicare Supplement Insurance (Medigap)

Medigap policies are private insurance plans that help pay for some of the out-of-pocket costs that Original Medicare doesn’t cover, such as deductibles, coinsurance, and copayments.

What Medigap Covers

Medigap policies are standardized, meaning that each plan letter (e.g., Plan A, Plan G) offers the same basic benefits regardless of the insurance company.

• Coverage Details:

Medigap policies can help pay for Part A and Part B deductibles, coinsurance, and copayments.

Some plans also offer coverage for foreign travel emergency care.

• Limitations:

Medigap policies don’t cover prescription drugs. You’ll need to enroll in a separate Part D plan for prescription drug coverage.

Medigap policies are only available if you have Original Medicare (Parts A and B). You can’t have a Medigap policy and a Medicare Advantage plan at the same time.

Actionable Takeaway: If you want comprehensive coverage and are willing to pay a higher premium, consider a Medigap policy to supplement Original Medicare.

Enrollment and Guaranteed Issue Rights

The best time to enroll in a Medigap policy is during your Medigap open enrollment period, which starts when you’re 65 or older and enrolled in Medicare Part B.

• Guaranteed Issue Rights: During your Medigap open enrollment period, you have guaranteed issue rights, meaning insurance companies can’t deny you coverage or charge you a higher premium based on your health.
• After Open Enrollment: Outside of your open enrollment period, it may be more difficult to get a Medigap policy, and insurance companies may be able to deny you coverage or charge you a higher premium. However, in some circumstances you may be eligible for guaranteed issue rights outside of the open enrollment period.
• Actionable Takeaway: Enroll in a Medigap policy during your open enrollment period to ensure you have access to the best coverage at the lowest possible price.
• Example: Many choose Medigap Plan G because it covers most of the cost-sharing associated with Medicare Parts A and B, aside from the Part B deductible.
