OAR 410-125-1080: Documentation

(1) Federal regulations require Medicaid providers to maintain records that fully support the extent of services for which payment has been requested, and that such records be furnished to the Division upon request (42 CFR 431.107). (2) When requested by the Division or its medical review contractor, hospitals must submit sufficient medical documentation to verify the emergency nature, medical necessity, quality and appropriateness of treatment, and appropriateness of the length of stay for inpatient and outpatient hospital services. The Division may request sufficient information to evaluate the accuracy and appropriateness of ICD-10-CM Coding for the claim. In addition, the Division may request an itemized billing for all services provided. The Division will specify in its request what documentation is required.
