@jwool89 I'd like to underline the comment from @colleenyoung that your "quarterback" will be the pulmonologist that you plan to see at Mayo Clinic. I have been a patient at Mayo Clinic for 5 years. We drive about 250 miles from our home in Michigan to Mayo Clinic in Rochester. I can assure you that if the pulmonologist at Mayo Clinic refers you to other departments, those appointments will be scheduled, if at all possible, while you are already at Mayo Clinic. I know it's difficult to plan how long you will stay in Rochester and your flight back home however as @colleenyoung wrote the hotels are very accustomed to extending their guests' stay as needed. As for your flight back home it is fortunate that airlines no longer charge those exorbitant change fees.

Your appointments and contacts will be on the Mayo Clinic patient portal. It's possible that you already have been scheduled for tests or other appointments ordered by the pulmonologist. Have you checked the Mayo Clinic patient portal?
