Colorado Medigap (Medicare Supplement) Plans
Medigap plans in Colorado help cover out-of-pocket costs not paid by Original Medicare, including the Part A deductible, Part B coinsurance, and skilled nursing facility copays. Medigap plans are standardized by federal law, meaning Plan G from one carrier covers the same benefits as Plan G from another carrier. The difference is premium cost.
Plans available in Colorado: A, B, D, G, K, L, M, N (plus high-deductible F and G; C and F only for those eligible before 2020)
Most popular plan: Plan G is the most popular Medigap plan in Colorado. Plan G covers all gaps in Original Medicare except the annual Part B deductible ($283 in 2026). Plan N is the most popular lower-premium alternative, with small copays for some doctor visits and ER visits.
Pricing method: Colorado uses community-rated Medigap pricing. This is the most favorable method for consumers because premiums are the same regardless of age. Your premium will not increase simply because you get older.
Colorado Medigap Switching Rights
Colorado does not have a Medigap birthday rule. Your primary opportunity to buy or switch Medigap plans without medical underwriting is during your initial Medigap Open Enrollment Period, which lasts 6 months starting when you first enroll in Medicare Part B at age 65 or older.
After your initial OEP closes, you may face medical underwriting if you apply for a new Medigap policy. However, federal law provides guaranteed issue rights in specific situations, such as losing employer coverage or leaving a Medicare Advantage plan during your first year.
Colorado guaranteed issue protections: Colorado follows the federal guaranteed issue rights and additionally requires Medigap insurers to sell to Medicare beneficiaries under 65 who qualify through disability, with state rules limiting how much more they can be charged.

Colorado Medicare Advantage (Part C)
Medicare Advantage plans in Colorado are offered by private insurers as an alternative to Original Medicare. Most MA plans include prescription drug coverage (Part D) and often add dental, vision, and hearing benefits. However, MA plans use provider networks, which can limit your choice of doctors and hospitals.
Key Medicare Advantage considerations in Colorado:
- Networks matter: HMO plans require you to use in-network providers except in emergencies. PPO plans allow out-of-network care at higher cost.
- $0 premium plans: Many Colorado MA plans have $0 monthly premiums (you still pay your Part B premium).
- Maximum Out-of-Pocket (MOOP): MA plans cap your annual spending, unlike Original Medicare which has no cap.
- Star ratings: CMS rates MA plans 1-5 stars. Higher-rated plans often have lower costs and better coverage.
Colorado Medicare Financial Help Programs
Colorado offers Medicare Savings Programs (MSPs) that help low-income Medicare beneficiaries pay for premiums, deductibles, and copays. The four programs are:
- QMB (Qualified Medicare Beneficiary): Pays Part A and Part B premiums, deductibles, coinsurance, and copays.
- SLMB (Specified Low-Income Medicare Beneficiary): Pays Part B premiums only.
- QI (Qualifying Individual): Pays Part B premiums (limited funding, first-come first-served).
- QDWI (Qualified Disabled Working Individual): Pays Part A premiums for disabled workers.
Colorado MSP eligibility: Federal 2026 limits (single): QMB $1,350, SLMB $1,616, QI $1,816 per month; asset limit $9,950 single / $14,910 couple. Applied for through Health First Colorado (Medicaid), not Medicare.
Apply through your local SHIP office or your state Medicaid agency for free help determining eligibility.
Top Medicare Insurance Companies in Colorado
When comparing carriers, focus on premium cost (for identical standardized Medigap plans, benefits are the same — only price differs), financial strength ratings from AM Best (A or higher), customer satisfaction ratings, and claims processing speed.
Colorado Medicare Enrollment Periods
Understanding Medicare enrollment deadlines prevents costly late enrollment penalties:
- Initial Enrollment Period (IEP): 7-month window around your 65th birthday (3 months before, birthday month, 3 months after). Enroll in Parts A and B during this period.
- Medigap Open Enrollment: 6 months starting the month you are 65 or older and enrolled in Part B. During this period, insurance companies cannot deny you Medigap coverage or charge higher premiums based on health conditions.
- Annual Enrollment Period (AEP): October 15 through December 7 each year. Switch between Original Medicare and Medicare Advantage, change MA plans, or add/change Part D drug plans.
- Medicare Advantage Open Enrollment Period (OEP): January 1 through March 31. Switch MA plans or return to Original Medicare (and add a Medigap plan, subject to underwriting).
- Special Enrollment Periods (SEP): Available when you lose employer coverage, move, or qualify for other life events.
Additional Colorado Medicare protections: Colorado had 30 insurers offering Medigap for 2026, about 108 Medicare Advantage plans, and 97 percent of residents can buy a $0-premium Advantage plan; the Division of Insurance publishes a yearly Medigap premium comparison guide.
