No matter what you use "is it implied consent"
you aren't
circumventing HIPPA. Implied consent is there for adults who physically cannot give consent (ie. are unconscious, mentally impaired, etc) or for minors when parents/guardians cannot be contacted or delay of treatment would result in loss of life. This differs from informed consent which is voluntary.
Unless you are wearing something that states not to treat you (ie. a DNR band) and they fish you out of the sea, you are going to be treated (of course taking local protocol into account). The DAN tag will just help them in the information gathering process.
Either way, how does this violate patients privacy? By the way, for information on what HIPPA actually is/does, look here:
