The governing body of each county shall provide access to institutional medical personnel whenever necessary to render medical aid to sick inmates whether awaiting trial or serving a sentence and to preserve the health of the inmate in the county jail, detention facility, prison camp, or other local facility used for the detention of inmates. The fees and expenses of such medical services, as well as for medicines prescribed, shall be paid out of any available funds. This section does not affect the requirements of § 24-13-80 or other existing federal, state, county, or municipal requirements that provide for the medical care of inmates.
