Medicaid Hospital Cost Reports Archive

Medicaid hospital cost reports are listed by their fiscal year, report type (H-hospital, P-psychiatric subprovider, R-rehabilitation subprovider), and facility ID (file provided with each Medicare ID, Medicaid ID, city, hospital name, and fiscal year begin and end dates).

All hospitals in Illinois, those hospitals in contiguous states providing 100 or more paid acute inpatient days of care to Illinois Medicaid Program participants, and all hospitals located in states contiguous to Illinois that elect to be reimbursed under the methodology described in 89 Ill. Adm. Code 149 (the Diagnosis Related Grouping (DRG) Prospective Payment System (PPS)), shall be required to file Medicaid and Medicare cost reports within 150 days after the close of that provider's fiscal year.
