Nothing personal I'm sure, but what wouldn't trigger the HIPAA police?
I am thinking about using this ability to send a SMS text from email if they want to give me the name of their phone service carrier.
http://sms411.net/how-to-send-email-to-a-phone/I would use it to let the patient know they have a new message in the Updox portal.
I am also thinking I could use it to remind them they have an appointment tomorrow. Does that raise the HIPAA hairs on the back of your neck? Anything else you would try to get away with?
