The Oregon Health Authority shall recommend fee schedules to be used in determining the dollar fee to charge a person admitted to approved alcohol and drug abuse prevention, early intervention and treatment services for the expenses incurred by the service in offering alcohol and drug abuse prevention, early intervention and treatment services. An individual facility may adopt the schedules developed by the authority or may, subject to the approval of the authority, develop and adopt its own fee schedules. The fee schedules adopted by each facility shall be applied uniformly to all persons admitted to the facility and shall be based on the costs of a person’s alcohol and drug abuse prevention, early intervention and treatment services and the ability of the person to pay. The person admitted shall be liable to the facility only to the extent indicated by the fee schedules. [1973 c.682 § 10; 1977 c.856 § 15; 1987 c.53 § 11; 2009 c.595 § 491]
