Once you're enrolled in Original Medicare (Parts A and B), you'll quickly discover that Medicare doesn't cover everything. That 20% coinsurance in Part B has no limit. A major surgery could cost you tens of thousands of dollars out of pocket.
This is where you have a critical decision to make: Medicare Advantage or Medicare Supplement (Medigap). Both provide valuable coverage, but they work very differently. Let's compare your options so you can choose the path that's right for you.
Medicare Supplement (Medigap): You keep Original Medicare and add a supplemental policy to cover out-of-pocket costs like deductibles, copays, and coinsurance. You also add a separate Part D plan for prescriptions.
Medicare Advantage (Part C): You replace Original Medicare entirely. A private insurance company manages all your care—medical, hospital, and usually prescriptions—through one plan.
Think of it this way: Medigap adds to Medicare. Medicare Advantage replaces Medicare.
You keep Original Medicare (Parts A and B), add a Medigap policy to fill the gaps, and add a Part D plan for prescriptions. You can see any doctor in America that accepts Medicare—no networks, no referrals, no prior authorizations.
Monthly Premiums: Medicare Supplement (Plan G or N) costs $100-250+ per month depending on your location and age. Add Part B premium ($202.90) and Part D ($0-100+). Total typical monthly cost: $350-500.
Out-of-Pocket Costs: Minimal after you meet the Part B deductible ($283). Plan G covers virtually everything Medicare doesn't. Plan N has small copays ($20 for doctor visits, $50 for ER).
You travel frequently or live in multiple states. See any Medicare doctor nationwide. Perfect for snowbirds.
You want predictable costs. Higher monthly premiums, but minimal surprise bills.
You have ongoing health needs. Chronic conditions requiring specialist care. No network restrictions.
You value maximum flexibility. Choose your own doctors, no referrals needed, no prior authorizations.
Medicare pays a private insurance company to manage your care. You get all Part A and B benefits, usually Part D prescriptions, and often extra benefits like dental, vision, and hearing—all through one plan.
Monthly Premiums: Many plans cost $0 in additional premium (you still pay Part B $202.90). Some charge $20-100+ monthly. Total typical monthly cost: $200-300.
When You Use Services: You pay copays: $0-35 for primary care, $30-50 for specialists, $250-400/day for hospital stays (typically days 1-5). Prescriptions have separate copays based on drug tiers.
Out-of-Pocket Maximum: Plans cap your annual costs at $3,000-8,000. Once you hit this limit, the plan pays 100% for covered services the rest of the year.
You want lower monthly premiums. Pay less each month, pay when you use services.
You prefer all-in-one simplicity. One card, one plan, medical and prescriptions together.
You stay local. Don't travel extensively, comfortable with network restrictions.
You value extra benefits. Dental cleanings, vision exams, hearing aids, gym memberships included.
You're generally healthy. Fewer doctor visits means lower total annual costs.
Medigap: Any doctor accepting Medicare nationwide. No networks.
Medicare Advantage: Must use plan network (HMO) or pay more (PPO).
Medigap: Not needed.
Medicare Advantage: Often required (HMO plans).
Medigap: $350-500 total (Part B + Supplement + Part D).
Medicare Advantage: $200-300 total (Part B + plan premium).
Medigap: Minimal costs after deductible. Supplement covers most.
Medicare Advantage: Copays for each service ($20-50 per visit).
Medigap: None, but supplement covers most costs anyway.
Medicare Advantage: Yes, $3,000-8,000 annually.
Medigap: Separate Part D plan required.
Medicare Advantage: Usually included in plan.
Medigap: None.
Medicare Advantage: Often includes dental, vision, hearing, fitness.
Medigap: Yes, nationwide + some foreign travel emergency coverage.
Medicare Advantage: Limited (network-based, emergency only when traveling).
Easy. Switch during Annual Enrollment Period (October 15 - December 7). No medical underwriting required.
More difficult after your initial enrollment period. You may face medical underwriting, which means you could be denied or charged higher rates based on your health.
Important: If you think you might want Medigap, it's often better to start with it. Switching from Medigap to Medicare Advantage is easier than the reverse.
