Relating to the submission, payment, and audit of certain claims for and utilization review of health services, including services provided under the Medicaid managed care and child health plan programs.

HB 4585 amends Texas Medicaid claims processing rules to set specific payment deadlines for healthcare providers. It requires Medicaid managed care organizations to pay clean claims within 10 days for nursing facility services, 30 days for long-term services, or 45 days for other claims (or via written agreement up to 60 days). The bill also mandates these organizations to disclose claim processing addresses, contact details, and any delegated entities to providers, with 61-day advance notice for changes. This directly affects Medicaid managed care organizations and healthcare providers (like doctors and facilities) submitting claims under Medicaid managed care and child health programs. The changes aim to improve payment transparency and timeliness for services covered by Texas Medicaid.
