Louisiana Prior Authorization Rules and Appeal Timeline


Louisiana law establishes clear timelines for prior authorization decisions and requires specific clinical justification for denials. Understanding these rules helps you obtain timely coverage decisions and successfully appeal denials.

Louisiana R.S. §22:1002 (2022 Amendment) Response Timelines

Louisiana R.S. §22:1002, amended in 2022, requires health insurers to respond to prior authorization requests within strict timelines: urgent or expedited requests within 72 hours of receipt, and standard requests within 14 days of receipt.

Emergency Services Exception

Emergency services are exempt from prior authorization requirements. Insurers cannot require preapproval for emergency care, but may conduct retrospective review of emergency claims within 30 days of service.

Required Clinical Criteria in Denials

When an insurer denies a prior authorization request, the denial must include the specific clinical criteria used to make the decision and the evidence-based rationale supporting the denial. Vague or conclusory denials lacking clinical justification are insufficient.

Internal Appeal Timelines

Patients and providers have 180 days from the date of PA denial to file an internal appeal with the health plan. For urgent requests, an expedited internal appeal must be decided within 72 hours of receipt.

External Review by Louisiana Insurance Department

If the internal appeal is denied, patients or providers can request an independent external review through the Louisiana Insurance Department. The LDI conducts an impartial clinical review of the PA denial.

How to Appeal Denied PA in Louisiana

  1. Obtain the PA denial citing specific clinical criteria and evidence-based rationale.
  2. Prepare clinical evidence and peer-reviewed literature addressing each criterion stated in the denial.
  3. File an internal appeal with the health plan within 180 days of the denial (72 hours for urgent cases).
  4. Request an LDI external review if the internal appeal is denied.
