@pito583, Mayo does work with multiple insurances. It does get complicated and as a patient, I want to share some information that you can use to get answers for your question about Possible costs and Medicare coverage.

Here is a section in the Transplant Department Center about costs and insurances.

To Call or email Mayo to talk with a care team member.
