Medicare Supplement vs. Medicare Advantage in Colorado
The biggest Medicare decision for Colorado residents is whether to pair Original Medicare with a Medigap plan or to enroll in Medicare Advantage. Each path serves different priorities:
| Feature | Medigap (Plan G/N) | Medicare Advantage |
|---|---|---|
| Provider freedom | Any provider in U.S. | Plan network only |
| Travel coverage | Nationwide | Limited / emergency only |
| Monthly premium | $110 – $200 (Plan G, age 65) | Often $0 |
| Prior authorization | No | Yes, common |
| Drug coverage | Separate Part D | Usually bundled |
| Dental, vision, hearing | Not included | Usually bundled |
Medigap Plans Available in Colorado
- Plan G — most comprehensive plan available to those new to Medicare. Covers everything except the Part B deductible (~$257/yr).
- Plan N — lower premium, small copays ($20 office / $50 ER), no Part B excess charge coverage.
- Plan F — covers Plan G + Part B deductible. Closed to new enrollees after Jan 1, 2020.
- High-deductible Plans G and F — lower premiums, federally set annual deductible (~$2,870 in 2026).
📍 Colorado Medigap Rule
Like most states, Colorado follows federal Medigap rules: a one-time 6-month Open Enrollment Period starting the month you turn 65 and have Medicare Part B. Outside that window, carriers may use medical underwriting to deny coverage or raise rates.
