Medicare is federal health insurance with multiple ways to receive benefits. Original Medicare combines Part A hospital insurance and Part B medical insurance. Medicare Advantage delivers Medicare benefits through an approved private plan. Part D addresses outpatient prescription drugs.
Medigap is private insurance that can supplement certain cost sharing, the person's share of covered costs, left by Original Medicare. This unit establishes the structure first, then compares what the Medicare parts and supplemental arrangements do.
Learning path
- Medicare and Medigap: Original Medicare, Medicare Advantage, Medigap, enrollment context, and the distinction between a supplement and an alternative way to receive Medicare benefits.
- Medicare Coverage Types and Benefits: Parts A, B, C, and D at a high level, covered-service categories, cost sharing, plan-specific networks, and formularies that list covered drugs.
Apply the unit
A consumer with Original Medicare considers a Medicare Advantage plan and a Medigap policy.
- Compare the enrollment path, provider network, the plan's contracted providers, benefit structure, and what the Medigap policy may supplement; do not assume the two options can be stacked.
Study checkpoint
- Can you identify what each Medicare part broadly covers?
- Can you distinguish Medicare Advantage from Medigap?
- Can you explain why premiums, networks, and enrollment periods must be checked in current Medicare materials?
