Cancer treatment comes with a range of medical expenses. It's essential to understand how Medicare plans can assist in covering the costs of cancer treatment.

Medigap is Medicare Supplement Insurance that helps fill "gaps" in Original Medicare. While Medicare covers a significant portion of cancer treatment bills, it may not pay them in full. Medigap may be used to offset out-of-pocket costs associated with cancer treatment.

Here are some frequently asked questions about Medigap: 

Do cancer patients need a Medigap plan?

Having a Medigap plan won’t completely eliminate cancer treatment costs, but it can ease the burden since it covers out-of-pocket medical expenses not covered by Original Medicare. Before any cancer treatment, it's important to verify that the doctor or group accepts Medicare. This ensures your Medicare and Medicare supplemental insurance will be properly applied. Moffitt Cancer Center and Moffitt Medical Group accept Original Medicare, Medicare Supplements and Medicare Advantage plans.

What are some cancer-related medical expenses?

There is a range of expenses during cancer treatment including but not limited to:

  • Diagnostic services, including X-rays, ultrasounds, mammography, MRIs and CTs
  • Labwork
  • Pathology services 
  • Hospital and surgical costs, including anesthesia
  • Radiation treatment
  • Chemotherapy
  • Physical therapy
  • Home healthcare  

When is the best time to purchase a Medigap policy?

The Medigap six-month open enrollment period begins the month you turn 65. During this time you cannot be charged a higher premium or denied coverage due to a pre-existing health condition, including cancer. Medicare's annual opportunity to review and adjust coverage each year doesn't apply to Medicare supplement plans (Medigap). Enrollees get just one Medigap open enrollment period in their lifetime.

What do I need to know if I want to buy a Medigap policy?

Depending on your medical situation, you could need more or less coverage.

  • Compare plans and try to evaluate costs, risk and consider your health status
  • Decide on a plan you want to buy
  • Pick your policy
