Tex. Code of Criminal Procedure § 63.007

(a) At the time a report is made for a missing child or adult, the law enforcement officer taking the report shall give a medical record release form to the parent, spouse, adult child, or legal guardian who is making the report. The officer receiving the report shall endorse the form with the notation that a missing child or missing adult report has been made in compliance with this chapter. When the form is properly completed by the parent, spouse, adult child, or legal guardian, and contains the endorsement, the form is sufficient to permit any physician, health care facility, or other licensed health care provider in this state to release to the law enforcement officer presenting the release dental records, blood type, height, weight, X rays, and information regarding scars, allergies, or any unusual illnesses suffered by the person who is reported missing. Except as provided by Subsection (d), a medical record of a missing child may be released only if the medical record release form is signed by a parent or legal guardian.

(b) At any time a report is made for an adult missing person, the law enforcement officer taking the report shall complete a medical release form that states that the person is missing and that there is reason to believe that the person has not voluntarily relocated or removed himself or herself from communications with others. A release under this subsection is not valid unless it is signed by the adult missing person's:

(1) spouse;

(2) adult child who is reasonably available;

(3) parent; or

(4) legal guardian.

(c) A law enforcement officer who obtains medical records under this article shall send a copy of the records to the clearinghouse. A law enforcement officer who obtains records under this article, a law enforcement agency using the records, and the clearinghouse are prohibited from disclosing the information contained in or obtained through the medical records unless permitted by law. Information contained in or obtained through medical records may be used only for purposes directly related to locating the missing person.

(d) The judge of any court of record of this state may for good cause shown authorize the release of pertinent medical records of a missing child or missing adult.

(e) A physician, health care facility, or other licensed health care provider releasing a medical record to a person presenting a proper release executed or ordered under this article is immune from civil liability or criminal prosecution for the release of the record.
