Medicare Education

Medicare is a federal health insurance program with specific eligibility rules, enrollment timelines, coverage structures, and cost considerations. Understanding how the different parts work together is an important first step in making informed decisions about coverage.

This page provides a clear, factual overview of Medicare basics, including eligibility, enrollment periods, and how Parts A, B, C, and D function.

Important Information

This information is provided for educational purposes only and is not affiliated with or endorsed by the U.S. government or the federal Medicare program.

Plan availability, benefits, costs, and enrollment rules are subject to change. Individual circumstances vary, and coverage decisions should be based on your specific situation.

We do not offer every plan available in your area. We currently represent multiple organizations that offer a range of products in your area. Please contact Medicare.gov, 1-800-MEDICARE, or your local State Health Insurance Assistance Program (SHIP) for information on all your options.

When You Are Eligible for Medicare

Most individuals become eligible for Medicare at age 65. You may also qualify before age 65 if:

You have received Social Security Disability Insurance (SSDI) benefits for 24 months
You have been diagnosed with Amyotrophic Lateral Sclerosis (ALS)
You have End-Stage Renal Disease (ESRD) and meet Medicare eligibility rules for ESRD.

If you are already receiving Social Security or Railroad Retirement Board benefits at least four months before turning 65, enrollment in Medicare Part A and Part B is typically automatic.

If you are not receiving those benefits, you must actively enroll during your Initial Enrollment Period.

Understanding Enrollment Periods

Medicare has defined enrollment windows that determine when you can sign up and whether late enrollment penalties may apply.

Initial Enrollment Period (IEP)

A seven-month period that begins three months before the month you turn 65, includes your birth month, and ends three months after.

General Enrollment Period (GEP)

January 1 through March 31 each year for individuals who did not enroll when first eligible. Coverage begins after you enroll, based on Medicare’s coverage start rules for that enrollment period.

Annual Enrollment Period (AEP)

October 15 through December 7 each year. During this time, individuals can change Medicare Advantage or Part D plans for coverage effective January 1.

Special Enrollment Periods (SEP)

Available in certain situations, such as delaying Part B due to qualifying employer coverage.

Late enrollment penalties may apply to Part B and Part D in certain circumstances if coverage is delayed without qualifying creditable coverage.

Understanding the Parts of Medicare

Medicare Part A

Part A helps cover inpatient hospital care, skilled nursing facility care following a qualifying hospital stay, hospice care, and limited home health services.
Most individuals do not pay a premium for Part A if they or their spouse paid Medicare taxes for a sufficient period.

Medicare Part B

Part B helps cover outpatient care, physician services, preventive services, durable medical equipment, and certain medically necessary services.
Part B requires a monthly premium and includes an annual deductible and cost-sharing.

Medicare Part C (Medicare Advantage)

Medicare Advantage plans are offered by private insurance companies approved by Medicare. These plans provide Part A and Part B coverage and often include additional benefits.
Individuals enrolled in Medicare Advantage must continue paying their Part B premium.
Costs, provider networks, and coverage rules vary by plan.

Medicare Part D

Part D provides prescription drug coverage through private plans approved by Medicare.
Each plan has its own formulary, cost structure, and pharmacy network. Late enrollment penalties may apply if creditable prescription coverage is not maintained when first eligible.

Each part of Medicare has different rules, costs, and enrollment requirements. Reviewing how they work together is an important step before choosing coverage.

Original Medicare and Supplemental Coverage

Original Medicare consists of Part A and Part B. Individuals enrolled in Original Medicare may choose to:

Add a standalone Part D prescription drug plan
Purchase a Medicare Supplement (Medigap) policy to help cover certain out-of-pocket costs

Medigap policies are standardized by federal law and help cover specific cost-sharing expenses but do not include prescription drug coverage.

Medicare Advantage Plans

Medicare Advantage plans are an alternative way to receive Medicare benefits through private insurers.

These plans may include additional benefits beyond Original Medicare and often operate with provider networks such as HMOs or PPOs.

Plan costs, out-of-pocket maximums, referral requirements, and coverage details vary.

Important Cost Considerations

When evaluating Medicare coverage, it is important to consider:

Monthly premiums
Deductibles and cost-sharing
Provider access and network limitations
Prescription drug formularies
Out-of-pocket maximums (for Medicare Advantage plans)
Coordination with employer or retiree benefits

Every individual’s situation is different, and reviewing these factors carefully can help avoid unexpected expenses.
