Reimbursement rates for nursing homes shall reflect the following objectives:
(1) maintain an equitable and fair balance between cost containment and quality care in nursing homes;
(2) encourage nursing homes to admit persons without regard to their source of payment;
(3) provide an incentive to nursing homes to admit and provide care to persons in need of comparatively greater care;
(4) be manageable administratively for both the State and nursing homes; and
(5) prevent unnecessary cost increases.
