It's important to know that if a doctor emails you with medical advice, he is breaking the law and can be seriously punished. The HIPAA laws are very strict about confidentiality, and email is considered non-confidential. On theo ther hand, you can communicate by fax, which is secure.
Some doctors participate in secure email networks that are marketed by internet companies. Medem is one of them. But a doctor using email for anythign besides appointments is putting hismelf or herself in jeopardy.
You all get these HIPAA forms to sign when you go to a new doctor, right?
It's about this stuff.
