What should I do if an overseas cardiac center asks for my local doctor's contact information, but I haven't obtained the doctor's consent yet?

First, ask your local doctor or their institution whether they agree to be contacted and what contact details and medical information they permit sharing. Then, confirm with the overseas facility the purpose of the contact, the expected method, and any required authorization documents. Until consent is obtained, you may provide the medical institution's public contact information or explain that you cannot provide it yet. Do not submit the doctor's private contact information without permission.
