Chris Antrim, CLTC - Boise Health & Life Agency • August 25, 2025
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) |
|---|---|---|
| Monthly Premium | Often lower | Higher |
| 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 |

Boise‑Specific Considerations
- Keep your specialists? We verify network participation before you enroll.
- Predictable spending? Supplements can smooth out surprises at a higher monthly cost.
- Medications? We run Part D or MAPD drug analyses so you’re not overpaying.
