Under Public Act 96-0941 (pdf) (html), Healthcare and Family Services (HFS) must provide information on the medical services that Medicaid reimburses. This data release is intended to provide easily accessible, understandable and useable data to all interested people, including researchers, healthcare providers, and individuals. HFS hopes to provide a way for evidence-based increases in the quality of Medicaid services, as well as reductions in the waste and fraud in the benefits system. Identical data is published on https://data.illinois.gov.
HFS welcomes your feedback on this data release.
Under the law, HFS must disclose the names of providers and vendors, their county, and the number of patients they serve; the payments, average costs and adjustments of the bills they submit to HFS; and the total amount of money they have received from HFS. We voluntarily provide additional information on the types of service Medicaid providers gave to recipients.
