We used Tricare Prime a couple of years ago at Mayo. My husband had surgery for prostate cancer. Tricare requires a referral from your PCP. It is always good to go to your Tricare account and double check that your pre-authorization has been approved before visiting. Here is a link to Mayo's Tricare info: https://www.mayoclinic.org/patient-visitor-guide/billing-insurance/insurance/accepted-insurance/champus-tricare. Here is the link to all Mayo's insurance information so you can check to see if your present insurance is accepted. You would need to check the Mayo Campus that you plan to visit to see if they contract with your insurance. https://www.mayoclinic.org/patient-visitor-guide/billing-insurance/insurance/accepted-insurance
