Medicare in Colorado
Free counseling, Medigap rules and help paying costs in Colorado.
Medicare is a federal program, so Parts A and B work the same way in Colorado as everywhere else. What changes by state is who can buy a Medicare Supplement (Medigap) policy and when, which private plans are sold where you live, and the state programs that help with costs.
Free Medicare counseling in Colorado
Colorado’s State Health Insurance Assistance Program (SHIP) is Colorado State Health Insurance Assistance Program (SHIP). Its counselors give free, one-on-one help with enrollment, comparing plans, Medigap, and programs that lower costs. They don’t sell insurance. Read more about what a SHIP counselor can do.
Medigap if you’re under 65
Insurers must sell Medigap to people under 65 on Medicare because of a disability, including ESRD, during their open enrollment window, though premiums may be higher than at 65.
Federal law only guarantees a Medigap Open Enrollment Period to people 65 and older, so state law decides what’s available before then. See Medicare under 65 on disability.
Switching Medigap plans in Colorado
Colorado has no birthday or anniversary rule. Outside your 6-month Medigap Open Enrollment Period and the federal guaranteed issue situations, an insurer can generally ask health questions, charge more, or decline your application when you switch policies.
Every state also has the federal guaranteed issue rights, such as losing employer coverage or a Medicare Advantage plan leaving your area. See Medigap guaranteed issue rights and switching Medigap plans.
Help paying Medicare costs in Colorado
Colorado’s Medicaid program (Health First Colorado) also runs the Medicare Savings Programs, which can pay your Part B premium and, for some people, deductibles and coinsurance. States may set limits higher than the federal minimums, so apply even if your income is a little over them. Qualifying for one also gets you Extra Help with drug costs automatically.
If you qualify for both Medicare and full Health First Colorado coverage, read Medicare and Medicaid together.
Medicare Advantage and Part D plans in Colorado
Medicare Advantage and Part D plans are sold by county, so the plans, premiums and networks available in one part of Colorado can differ from another. The Medicare Plan Finder lists every plan for your ZIP code. You can change plans during Medicare Open Enrollment, October 15 to December 7.
