Choosing between Medicare Advantage and a Medicare Supplement (Medigap) is about trade‑offs: premium vs flexibility, network rules vs nationwide access. Here’s a clear breakdown tailored to Boise.
Side‑by‑Side Comparison
Category | Medicare Advantage (Part C) | Medicare Supplement (Medigap) |

Networks | HMO/PPO; check St. Luke’s/St. Al’s | Any Medicare provider |
Out‑of‑Pocket Risk | Annual maximums apply | Low/predictable with right plan |
Rx Coverage | Usually built‑in (MAPD) | Separate Part D needed |
