… What is the difference between the way that HIPAA treats the subject of parental access to a minor’s records and the way your state law treats the issue? Likely none, since HIPAA essentially defers to state law regarding the subject. Not so with other issues, where state law and HIPAA may conflict. If one is a “covered provider,” for example, state law may have to give way to HIPAA requirements, like in those states where HIPAA provides the adult patient with greater rights to access his or her records than does the state law.
