Section 1166 - Medicaid reimbursement(a) The Medicaid reimbursement program shall be adjusted to reflect costs associated with the increased staffing levels described herein. Reimbursement rates for nursing wages will be adjusted to the 75th percentile under the current wage determination methodology for primary care under the state Medicaid program.(b) The Department shall ensure that 100% of Medicaid funds paid for primary care are expended by the residential health facility for primary care purposes. If, during any annual cost reporting period, a facility expends less than 100% of the primary care reimbursement it receives from Medicaid for primary care, the sum under-spent must be repaid to the Medicaid program. The repayment will be made through a cost settlement process when the provider files its annual cost report. The Department will revise its regulations and Medicaid cost report forms to require a cost settlement for the primary care reimbursement classification.(c) Medicaid reimbursement of providers shall be consistent with the provisions of this chapter regardless of the payment methodology employed by Medicaid or its contractors, including managed care. 72 Del.
