HB 2065 requires Oklahoma Medicaid to reimburse healthcare providers for multiplex respiratory PCR testing (using CPT codes 87636 and 87637) when testing symptomatic patients in emergency rooms or urgent care settings. This bill directly affects hospitals and clinics participating in Oklahoma Medicaid by mandating coverage for tests that detect multiple respiratory viruses simultaneously, including COVID-19, influenza A/B, and RSV. The reimbursement applies to tests aligned with clinical best practices for diagnosing acute respiratory illnesses. The bill takes effect on November 1, 2025.
