In short
- Medicare pays its share first.
- Then Medigap pays what you owe under your policy.
- You are responsible for any costs that are left.
What this means
Medicare.gov says how the two work together. When you have a Medigap policy and get care, Medicare pays its share first. It pays its share of the Medicare-approved amount [1]. Then your Medigap policy pays your doctor what you owe under your policy. You are responsible for any costs that are left [1].
The page does not say what Medigap does with a service Medicare refused to cover. So this answer stops at the order of payment.
Your next step
Check your own Medigap policy for how it treats a service that Medicare refused to cover. The page describes only the order of payment [1]. The sources give no deadline.
Check it yourself
Your Medigap policy papers say what the plan letter you bought pays. Medicare.gov's page on how Medigap works is the source above; the answer for a refused service is "Don't know yet".

If you have a Medigap policy and get care, Medicare will pay its share of the Medicare-approved amount for covered health care costs. In most Medigap policies, you agree to have the Medigap insurance company get your Part B claim information directly from Medicare. Then, your Medigap policy will pay your doctor whatever amount you owe under your policy and you're responsible for any costs that are left
