Federal law and regulations impose significant restrictions with respect to the disclosure of information about persons who receive alcohol or drug prevention or treatment services from a federally assisted program. 
The federal law and regulations generally prohibit the disclosure of “patient identifying” information by federally assisted programs and others.
Disclosure, however, is permitted:
with the patient’s written consent;
in response to a court order;
to the extent necessary to comply with state laws requiring the reporting to appropriate state or local authorities of suspected child abuse or neglect; or
for other purposes specified in the federal law and regulations. 
No state law may authorize or compel any disclosure that is prohibited by these federal rules. State law, however, may prohibit the disclosure of information that would be allowed under the federal law and regulations.
