Nev. Rev. Stat. § 435.670
The expense of diagnostic, medical and surgical services furnished to a consumer admitted to a division facility by a person not on the staff of the facility, whether rendered while the consumer is in a hospital, an outpatient of a hospital or treated outside any hospital, must be paid by the consumer, the guardian or relatives responsible pursuant to NRS 435.655 for the consumer's care. In the case of an indigent consumer or a consumer whose estate is inadequate to pay the expenses, the expenses must be charged to the county from which the admission to the division facility was made, if the consumer had, before admission, been a resident of that county. The expense of such diagnostic, medical and surgical services must not in any case be a charge against or paid by the State of Nevada, except when, in the opinion of the administrative officer of the division facility to which the consumer is admitted, payment should be made for nonresident indigent consumers and money is authorized pursuant to NRS 435.475 and the money is authorized in approved budgets.
