Part B coinsurance or copayments
Blood (first 3 pints)
Part A hospice coinsurance or copayments
Skilled nursing facility coinsurance (with some plans)
Part A & Part B deductibles (with some plans)
Foreign travel emergency care (with some plans)
Coverage depends on the Medigap plan letter you choose (Plans A–N).
What Medigap Doesn’t Cover
Prescription drugs (you need Part D for this)
Routine vision, dental, hearing aids
Long-term care
Private-duty nursing

Maria’s Story:
Maria, age 66, has Original Medicare (Parts A & B) and a Medigap Plan G. When she needed knee replacement surgery, Medicare paid most of the bill. Her Medigap policy covered her Part A deductible and most of her out-of-pocket costs. Maria had predictable, manageable costs for her care.
⚠️ Important: You cannot have both a Medicare Advantage plan and a Medigap policy at the same time.
