Medicare Advantage vs. Medigap 2026: Compare Costs, Coverage, Pros & Cons
Short answer: Medicare Advantage plans often have lower premiums but come with networks and managed care rules. Medigap plans cost more but offer broader access, travel flexibility, and predictable costs. The best choice depends on your healthcare needs, travel plans, and comfort with out-of-pocket costs. Lifestyle-First planning helps you budget for premiums, co-pays, and surcharges so your Medicare choice fits your real life.
Original Medicare: The Foundation
Original Medicare (Parts A and B) covers hospital and medical care, but leaves you responsible for about 20% of costs with no out-of-pocket maximum. That’s where Medigap (Medicare Supplement) or Medicare Advantage comes in to help cover what Medicare doesn’t.
What Is Medigap (Medicare Supplement)?
Medigap plans, like Plan G or Plan N, pay most or all of the costs that Original Medicare doesn’t cover. For 2026, a 65-year-old can expect to pay about $100–$250 per month for Plan G and $80–$200 per month for Plan N, depending on your location and insurer. Medigap lets you see any doctor or hospital that accepts Medicare, with no networks or referrals required. Most plans also cover 80% of emergency care abroad after a $250 deductible, up to a $50,000 lifetime limit. You have a 6-month guaranteed issue window when you first enroll in Part B at age 65.
What Is Medicare Advantage?
Medicare Advantage (Part C) plans are private insurance plans that bundle hospital, medical, and often drug coverage into one plan. Many have $0 or low monthly premiums, but you pay co-pays and coinsurance as you use care. Medicare Advantage plans have networks, so you may need to use certain doctors or hospitals, and you may need referrals for specialists. The annual out-of-pocket maximum (MOOP) for 2025 is $9,350 for in-network care, and $14,000 for combined in- and out-of-network PPO care. The 2026 MOOP is expected to be slightly higher.
Prescription Drug Coverage and Part D IRMAA
Most Medicare Advantage plans include prescription drug coverage. If you choose Original Medicare, you can add a stand-alone Part D plan. In 2026, the annual out-of-pocket cap for Part D drugs is $2,100. If your income is above certain thresholds, you may pay a Part D IRMAA surcharge, starting at $14.50 per month for singles with income over $109,000.
How Much Will Healthcare Cost in Retirement?
Fidelity estimates a 65-year-old couple retiring in 2026 will need about $330,000 for healthcare costs in retirement, not including long-term care. That’s why budgeting for premiums, co-pays, and surcharges is so important.
