1.    Notwithstanding any other law, a public health authority, or the agent of any such entity, may disclose protected health information to a law enforcement authority if the department of health and human services determines that:

a.    The protected health information is necessary to a legitimate law enforcement inquiry that has begun or may be initiated into a particular violation of a criminal law or public health law being conducted by the authority; and

b.    The investigative or evidentiary needs of the law enforcement authority cannot be satisfied by nonidentifiable health information or by any other information.

2.    If a public health authority discloses protected health information under this section, that authority shall impose appropriate written safeguards to ensure the confidentiality of the information and to protect against unauthorized or improper use or disclosure.

3.    Protected health information about an individual that is disclosed under this section may not be used in, or disclosed to any person for use in, any administrative, civil, or criminal action or investigation directed against the individual, unless the action or investigation arises out of, or is directly related to, the law enforcement inquiry for which the information was obtained.

4.    When the matter or need for which protected health information was disclosed to a law enforcement authority or grand jury has concluded, including any derivative matters arising from that matter or need, the law enforcement authority or grand jury must either destroy the protected health information or return it to the person from whom it was obtained.

5.    To the extent practicable, and consistent with the requirements of due process, a law enforcement authority shall redact personally identifying information from protected health information prior to the public disclosure of that protected information in a judicial or administrative proceeding.

6.    Any disclosure of protected health information under this section must be limited to the minimum amount of information necessary to fulfill the purposes of this section.

7.    A recipient of information pursuant to this section may use or disclose that information solely to fulfill the purposes of this section.

8.    Protected health information disclosed under this section must be clearly identified as protected health information that is subject to this chapter.

9.    This section may not be construed to limit or restrict the ability of law enforcement authorities to gain information while in hot pursuit of a suspect or if other exigent circumstances exist.
