It is declared by the legislature as a matter of public concern that the needy persons of this state who are eligible for medical care at public expense under this chapter should seek only uniform and high quality care that is appropriate to their condition and cost-effective to the state and receive that care, regardless of race, age, national origin, or economic standing. It is equally a matter of public concern that providers of services under this chapter should operate honestly, responsibly, and in accordance with applicable laws and regulations in order to maintain the integrity and fiscal viability of the state's medical assistance program, and that those who do not operate in this manner should be held accountable for their conduct. It is vital that the department administer this chapter in a manner that promotes effective, long-term cost containment of the state's medical assistance expenditures while providing medical care to recipients. Accordingly, this chapter authorizes the department to apply for participation in the national medical assistance program as provided for under 42 U.S.C. 1396 - 1396p (Title XIX, Social Security Act).
