How a Medigap plan works
A Medicare Supplement plan works with Original Medicare. You must have Part A and Part B. Medicare pays its share first. Then the supplement plan pays its share of the costs Medicare left behind, based on the letter you chose.
These plans do not include prescription drug coverage. For drug coverage, add a separate Part D plan: Medications and drug coverage.
A Medigap plan cannot be used with a Medicare Advantage plan. If you are weighing the two paths, start here: Medicare Advantage plans.
Every plan with the same letter covers the same benefits, from every company. What differs is the price and the company. See what each letter covers: Medicare Supplement plans, explained.
