If you suffered an injury or illness before becoming eligible for Medicare, you may wonder if it will affect your eligibility or coverage options.

Here’s a look at how Medicare works with preexisting conditions.

Your Medicare eligibility and coverage will not be affected

Preexisting conditions, also known as previous health conditions, do not affect your Medicare eligibility and coverage. Original Medicare (Part A and Part B) is available to any individual age 65 or older, younger than 65 with a disability, or any age with end-stage kidney disease (ESKD).1

Your conditions can be covered
