There is no single "best" Medicare plan. The right choice depends on your doctors, your prescriptions, how often you travel, and what you can afford each month. This guide lays out how each option actually works so you can make an informed call.
The Three Main Paths
Original Medicare
- Any doctor who accepts Medicare — nationwide
- No referrals required
- Predictable coverage rules
- No cap on out-of-pocket costs
- No dental, vision, or hearing
- Need separate Part D for drugs
Medicare Advantage
- Often $0 or low monthly premium
- Annual out-of-pocket cap (~$8,850 max)
- Usually includes dental, vision, hearing
- Network restrictions — must use plan's doctors
- Prior authorization requirements
- Plans vary widely by county
Medigap (Supplement)
- Covers deductibles, copays & coinsurance
- Any doctor nationwide who accepts Medicare
- Highly predictable costs
- Higher monthly premium ($100–$300+)
- No dental, vision, or hearing coverage
- Need separate Part D plan

Which Plan Fits Your Situation?
Original Medicare or Medigap
Both let you see any Medicare-accepting doctor in the country without a referral or network restriction.
Medicare Advantage
Many Advantage plans have $0 premiums in 2026. You pay more when you use care, but less each month.
Medigap Plan G or N
Medigap Plan G covers nearly all gaps — deductibles, copays, coinsurance — leaving you with very predictable costs.
Original Medicare or Medigap
Advantage plans are network-based and can leave you with limited coverage outside your plan's service area.
You can switch from Medicare Advantage back to Original Medicare during the Open Enrollment Period (Oct 15 – Dec 7) or the Medicare Advantage Open Enrollment Period (Jan 1 – Mar 31). However, getting Medigap after your initial enrollment window may require medical underwriting in most states.
