HB 2065 requires Oklahoma Medicaid to cover reimbursement for multiplex respiratory PCR testing (using CPT codes 87636 and 87637) for symptomatic patients in emergency rooms and urgent care settings. This bill directly affects Medicaid providers who perform these tests and patients seeking rapid diagnosis of respiratory illnesses like COVID-19, flu, or RSV. The key provision adds specific testing codes to Medicaid's reimbursement policy, aligning with clinical guidelines for diagnosing common respiratory infections. The change becomes effective November 1, 2025.
