The federal government urges people to buy a Medicare supplement policy, or Medigap, during their six-month initial enrollment period if they’re interested in Medigap.
During this period – which begins the first month you have Medicare Part B and you are 65 or older – you’re guaranteed coverage, even if you have health issues. You also can get coverage at the most favorable rates.
Once your personal open enrollment period closes, you may be denied for a policy due to poor health or end up paying more for coverage.
However, you might be able to sign up for Medicare supplement insurance if you are eligible under a specific circumstance or guaranteed issue rights. Medicare outlines these situations on its website.
