Frequently Asked Questions

What is a supplemental insurance agent in Castle Rock?
A supplemental insurance agent helps you buy Medicare Supplement or Medigap policies. These agents are licensed in Colorado and can explain plan options like Plan G or Plan N. They do not sell Medicare Advantage plans unless they also hold that certification.
When can I enroll in a Medicare Supplement plan in Colorado?
