Common questions
Straight answers to the questions people ask most when they're trying to enroll in Montana.
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 Part A and Part B?
In most cases, you enroll in Part A and Part B through Social Security. If you’re still working or have employer coverage, the timing can be different.
When should I sign up to avoid penalties?
Timing depends on your situation (turning 65, disability, employer coverage, and more). When in doubt, start planning a few months before you want coverage to begin.
What information should I have ready?
Common items include your Social Security number and details about current coverage if you’re enrolling due to a special situation. Save any confirmation numbers or letters after you submit.
