Medicare Supplement vs. Medicare Advantage

Choosing between a Medigap supplement and a Medicare Advantage plan is one of the biggest decisions you'll make. Here's how they compare.

Medicare Supplements (Medigap)

Medigap supplements work alongside Original Medicare (Parts A and B). They cover the gaps—deductibles, coinsurance, and copays—that Original Medicare doesn't pay. You still need a separate Part D plan for prescriptions.

Pros: Freedom to see any doctor that accepts Medicare nationwide, no referrals, predictable costs, and comprehensive coverage.

Cons: Higher monthly premiums (typically $150–$300), no extra benefits like dental or vision, and you need a separate Part D plan.

Medicare Advantage (Part C)

Medicare Advantage plans replace Original Medicare. Private insurers bundle Parts A, B, and usually D into one plan, often with extra benefits like dental, vision, hearing, and fitness programs.

Pros: Lower premiums (sometimes $0), out-of-pocket maximums, extra benefits, and prescription coverage included.

Cons: Network restrictions (HMO/PPO), referrals required for specialists, higher out-of-pocket costs when you use services, and plans can change annually.

Which Is Right for You?

Choose Medigap if: You want freedom to see any Medicare doctor, travel frequently, have chronic conditions requiring regular care, or prefer predictable costs.

Choose Medicare Advantage if: You want lower premiums, prefer one plan for everything, stay in your local area, and don't mind network restrictions.

Remember: You can switch between Medigap and Medicare Advantage during certain periods, but underwriting may apply for Medigap after your initial enrollment period.
