Idaho Code § 20-612
The sheriff must receive all persons committed to jail by competent authority except mentally ill persons not charged with a crime and juveniles. It shall be the duty of the board of county commissioners to furnish all persons committed to the county jail with necessary food, clothing, bedding, and medical care, and the board of county commissioners is authorized to pay therefor out of the county treasury under such rules and regulations as they may prescribe. The county's obligation herein shall not apply when the person is no longer committed to the county jail if the person has been released pursuant to a dismissal, bail, or any other court order of release, unless the release is a temporary release from the jail solely for the purpose of receiving medical care for an injury that occurred while committed in the county jail. Nothing in this chapter precludes a released person from access to coverage under chapter 35, title 31, Idaho Code.
