HB 1820 requires Oklahoma's Medicaid program to verify specific eligibility information (like income, residency, employment, and immigration status) before approving benefits, excluding TEFRA-eligible applicants and individuals with intellectual disabilities in Home and Community Based Waivers. It mandates quarterly reviews of enrolled Medicaid recipients for changes in circumstances and establishes a 10-business-day window for applicants to respond to discrepancies. The law directs the Oklahoma Health Care Authority to contract with independent vendors that demonstrate cost savings and to use data-sharing agreements with state agencies. This bill directly affects Medicaid applicants and recipients in Oklahoma by tightening eligibility verification processes, while exempting certain vulnerable groups from these requirements.
