Medicare Advantage vs Original Medicare
At age 65 you have two paths for Medicare coverage. The choice sounds simple but has real long-term consequences. Roughly half of beneficiaries pick each — meaning there's no single right answer.
| Original Medicare | Medicare Advantage | |
|---|---|---|
| Parts included | A (hospital) + B (medical); add D for drugs | A + B + usually D + extras all in one plan |
| Monthly premium | $185 Part B + optional Medigap (varies) | $185 Part B + often $0 plan premium |
| Provider network | Any doctor accepting Medicare (nationwide) | HMO/PPO networks (usually local) |
| Referrals | Not required | Often required (HMO) for specialists |
| Prior authorization | Rare | Common for imaging, surgery, home health |
| Out-of-pocket maximum | No cap (add Medigap to limit) | Capped ~$8,850/yr in-network (2026) |
| Extras (dental, vision, hearing) | Not covered | Often included |
| Coverage while traveling | Any US provider taking Medicare | Emergency only outside network |
| Ability to switch back later | N/A | Medigap medical underwriting after year 1 |
The One-Way Door You Should Know About
When you first sign up at 65, you have a guaranteed-issue right to Medigap — insurers must accept you regardless of health. If you enroll in Medicare Advantage first and later try to switch to Original Medicare + Medigap, most states allow insurers to medically underwrite — they can deny you or charge more based on health conditions. This means the choice at 65 is often practically permanent.
When Original Medicare Usually Wins
- • You value doctor choice nationwide without networks
- • You have complex health issues where specialists matter
- • You travel frequently or split time between states
- • You want minimal prior authorization friction on treatments
- • You can afford a Medigap plan (adds $150–$400/mo depending on state and plan)
When Medicare Advantage Usually Wins
- • You're generally healthy and prefer lower monthly costs
- • You want dental, vision, hearing, or gym benefits bundled in
- • Your preferred doctors are already in a strong network in your area
- • You want an annual out-of-pocket cap (Original Medicare has none unless you add Medigap)
- • You stay mostly in one region
