HB 3127 amends the Government and Insurance Codes to shorten the required response time for health benefit preauthorization requests. The bill mandates that Medicaid managed care organizations and workers' compensation health networks issue preauthorization determinations within three calendar days instead of business days. It also introduces a requirement for utilization review agents to provide notice of determinations within the shortest legally required timeframe, with these provisions applying to contracts and policies entered into or renewed on or after January 1, 2026​.
