Kan. Stat. § 65-116k
The secretary of health and environment is hereby authorized and directed to adopt rules and regulations establishing reasonable rates and administrative procedures to be followed in making payments to the medical care facilities and physicians providing care and treatment under the provisions of this act. Payments shall only be made directly to medical care facilities and physicians except that this act shall not be deemed to create any rights or causes of action against the state or the secretary of health and environment in such a medical care facility or physician, their heirs or assigns. No payments shall be made for expenses incurred prior to the time the secretary assumes payment responsibility and payments made by the secretary on behalf of an individual eligible for payments under the provisions of this act shall constitute a complete settlement of the claim upon which such payment is based.
