The most common benefits include:

  • Deductibles: Most Medigap plans in Colorado, except Plan A, cover the Medicare Part A deductible. This is the amount you spend on hospital costs before Medicare pays its share. Only Plans C and F cover the Part B deductible, but these are no longer sold to those eligible for Medicare after January 1, 2020.

  • Coinsurance: Coinsurance is the portion you pay for services after you've met your Part A or B deductible. Most Colorado Medigap plans cover Part A coinsurance for hospital and hospice care and Part B medical coinsurance. Plan N covers 100% of Part B coinsurance, except for a few situations, such as emergency room visits that don't require you to be admitted as an inpatient.

  • Foreign travel: Some plans, including Plans F, G and N, pay for emergency care if you're out of the country.

All plans in the same letter category provide the same coverage. Once you've selected the type of Medigap plan you need, you can see which insurance companies sell that particular plan in Colorado and compare the premiums and discounts offered.

How Do I Enroll in a Colorado Medigap Plan?

Seniors who are 65 and over have a six-month Medigap open enrollment period once they're signed up for Medicare Part B. This timing is important as you only get this window once. During this time frame, you can enroll in any Medigap plan sold in Colorado. Insurance companies can't deny you coverage or change your premiums based on your health. The plans are guaranteed renewable as long as you pay your premiums and maintain your coverage.

In some cases, you may not need Medigap right away because you're enrolled in Medicare Part C or have coverage through work. If this coverage ends, you may still have guaranteed issue rights to enroll in Medigap for 63 days. 

On rare occasions, for example, your insurance provider may go bankrupt or leave Medicare. You might also move out of your Medicare Advantage service area or decide, within a year, that the Part C plan isn’t meeting your needs and that you want to return to Original Medicare. In these scenarios, guaranteed issue rights let you enroll in any Medigap policy without an insurer underwriting the policy.
