One of the most common concerns about buying Medicare Supplement insurance is whether pre-existing conditions will prevent coverage or increase costs. Here’s how it actually works.
The Open Enrollment Window: Your Best Protection
Federal law gives every Medicare beneficiary a 6-month Medigap Open Enrollment Period that begins the month you are both age 65 or older and enrolled in Medicare Part B. During this window:
- Insurance companies cannot deny you coverage based on health conditions
- They cannot charge you more than a healthy applicant of the same age
- They must accept you for any Medigap plan they sell in your state
- They may impose a waiting period of up to 6 months for pre-existing conditions, but only in certain states
This is the single most important enrollment window in Medicare. Missing it can have lasting consequences.
