The biggest decision new Medicare beneficiaries face is choosing between Original Medicare + supplements vs Medicare Advantage. Each path has real trade-offs. About 50% of new beneficiaries pick Medicare Advantage in 2026, drawn by lower premiums and bundled extras. The other 50% pick Original Medicare, prioritizing flexibility.

Original Medicare Strengths

1. Provider flexibility — see any doctor accepting Medicare nationwide
2. No referrals — go to specialists directly
3. No prior authorization for most services
4. Stable — your “plan” doesn’t change annually
5. Same coverage anywhere in US (great for travelers, snowbirds)
6. Predictable costs with Medigap

Original Medicare Weaknesses

1. Higher monthly cost total (premiums for B + Medigap + Part D)
2. No out-of-pocket maximum without Medigap
3. Doesn’t cover dental, vision, hearing typically
4. Two cards needed (Medicare + Medigap)

Medicare Advantage Strengths

1. Lower monthly cost often (sometimes $0 above Part B)
2. Out-of-pocket maximum built in
3. Bundled extras — drug coverage, dental, vision, hearing, gym, transportation
4. One card for most coverage
5. Often coordinated care through PCP

Medicare Advantage Weaknesses

1. Network restrictions — must use plan’s providers
2. Referrals often required for specialists
3. Prior authorization common — sometimes denied
4. Plans change annually — must review yearly
5. Limited coverage outside service area
6. Some report difficulty switching back to Original after years on MA

Who Wins for Each Profile

Profile	Best Match
Healthy, want low premiums	Medicare Advantage
Snowbird (live in 2 states)	Original + Medigap
Travel internationally	Original + Medigap (with travel rider) or none
Live in rural area	Original (broader network)
Want bundled dental/vision	Medicare Advantage
Prefer minimum hassle	Medicare Advantage (one card)
Have specialists you want to keep	Original (no network restrictions)
Heavy medical user	Medigap-protected Original
Limited income	MA $0-premium plans + Extra Help
Live in major metro	Either works

Switching Between Them

From → To	When	Difficulty
Original → MA	Annual Election Period (Oct 15 – Dec 7)	Easy
MA → Original	Annual Election Period or MA OEP (Jan 1 – Mar 31)	Easy
Add Medigap after MA	Often subject to medical underwriting (if past initial enrollment)	Can be hard

The Medigap underwriting catch is important. If you choose MA initially and later try to switch to Original + Medigap, insurers can deny Medigap coverage based on health (in most states). This locks some people into MA.

Star Ratings

CMS rates Medicare Advantage and Part D plans 1–5 stars annually. Use ratings as one input:

• 5 stars = excellent
• 4 stars = above average
• 3 stars = average
• 1–2 stars = problematic

5-star plans have a Special Enrollment Period letting you switch any time.

Plan Stability

Medicare Advantage plans:

• Change annually (premium, copays, formulary, network)
• May exit your area
• May add or remove benefits
• Networks change too

Always review your plan annually during Annual Election Period. What worked last year may not work this year.

Decision Framework

Answer these questions:

1. Do you have specific doctors / hospitals you want to keep?

   • Yes → Original Medicare (verify they accept Medicare)
   • No → Either works

2. Do you travel or live in multiple states?

   • Yes → Original Medicare
   • No → Either works

3. Do you want bundled dental/vision/hearing?

   • Yes → Medicare Advantage
   • No → Either works

4. Can you afford $300–$500/month in premiums?

   • Yes → Original + Medigap is feasible
   • No → Medicare Advantage typically cheaper

5. Do you have predictable medical needs?

   • Yes → Original + Medigap (predictable cost)
   • No → MA’s out-of-pocket cap protects against surprise

6. Do you mind reviewing plans annually?

   • No → Original Medicare more stable
   • Yes → MA fine

Common Mistakes

1. Choosing MA solely on $0 premium — copays and restrictions may cost more
2. Not verifying providers in MA network before enrolling
3. Skipping Medigap during Open Enrollment — hard to add later
4. Not reviewing MA plan annually — features change
5. Not understanding prior authorization — surprise denials
