Common questions
Is this site affiliated with Medicare.gov or Social Security?
No. This site provides educational Medicare information and points you to official resources. We don’t offer plan recommendations.
Where do I sign up for Medicare in Boulder, Colorado?
In most cases, you sign up for Medicare Part A and Part B through Social Security. If you’re still working or have employer coverage, timing can be different.
When should I enroll to avoid penalties?
Timing depends on your situation (turning 65, disability, employer coverage, and more). If you’re unsure, start planning a few months before you want coverage to begin.
