You must have Medicare Part A and Part B to be eligible for a Medigap plan. But eligibility alone does not guarantee coverage.
If you apply during your initial enrollment period you can apply for any plan with any carrier and coverage is guaranteed. After that you must submit evidence of insurability unless you are applying during a guaranteed issue period.
