Common questions
How many Medicare Advantage plans are there in Colorado in 2027?
It depends on your county: from 2 in Baca County to 65 in Jefferson County. Plans are approved county by county, so two neighbours in different counties can have different choices. Pick your county below for the exact count.
How many Part D drug plans are there in Colorado?
8 standalone Part D plans from 4 companies in 2027, the same in every county. In 2026 there were 10.
Why do plan counts differ so much between counties?
Insurance companies decide where to offer each plan based on the doctors and hospitals they can contract with and how many people live there. Rural counties usually have fewer plans; metro counties have the most. Original Medicare and Medigap work the same everywhere.
Where do these numbers come from?
The Medicare Advantage and Part D Landscape file that CMS publishes each fall, which lists every approved plan by county for the coming year. This page uses the 2027 file released September 30, 2026. Employer-group plans are not included.
