Thank you, Colleen! I am glad to have the Office of Patient Experience info. I will be reaching out to them, however this plays out. After posting earlier, after I sent a message to Walt's Mayo cardiologist, I received a call from the head of the Mayo Pacemaker Clinic - I think my message on the Patient Portal had been routed to her. She wanted to make sure I "and the person from Barrows who had repeatedly called" understood the reason the form we needed would not be signed off on. She said the form asks for recommended settings for the pacemaker during the MRI, and that Mayo could not complete the form because they would not be at the MRI site or appt, and could not be responsible. I asked her for a copy of the form, which she said she did not have. I asked her if she was sure the form asked for settings, but she said she was not sure. Speaking to Barrow's again, I confirmed that the form is a standard form; it does ask for the recommended settings; and despite the fact that some doctors are reluctant, and that sometimes there is some delay - this is the first time she has ever received, from a specific medical group, a flat refusal to complete and sign the form. I then contacted the Pacemaker Clinic again and left a message that I wanted my Portal Message re-routed to the doctor, and that I expected a response. Inn the meantime, Barrow's called me back to tell me they were trying to arrange a short notice cardiology appointment there. Thank you for your suggestions. I will keep you posted....
