When the victim of any crime is directed or authorized by a law enforcement agency to obtain a medical examination for the purpose of procuring evidence for use by a law enforcement agency in the investigation or prosecution of the crime, the expense incurred shall be paid by the law enforcement agency. Provided however, the cost of forensic and/or medical examinations of alleged victims of sexual assault shall be paid for from the crime victims compensation account, as established by section 72-1009, Idaho Code. The provisions of this section shall not be construed to require a law enforcement agency to bear the expense of any medical treatment of the victim.
