Wisconsin Prior Authorization Rules and Appeal Timeline


Wisconsin law establishes clear timelines for prior authorization decisions and requires robust appeal processes. Understanding these requirements helps you obtain timely coverage decisions and overturn denials.

Wisconsin Stat §632.861 Response Timeline (2024 Update)

Wisconsin Stat §632.861, updated in 2024, mandates that health insurers respond to prior authorization requests within specific timeframes: standard requests within 7 business days, and urgent or expedited requests within 3 business days of receipt.

Emergency Services Exception

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

Prior Auth Denial Requirements

When an insurer denies a prior authorization request, the denial notice must include the specific clinical criteria that the requested service failed to meet and the qualifications of the reviewer who made the decision. Vague denials lacking clinical justification are insufficient.

Internal Appeal Timeline

Wisconsin patients and providers have 180 days from the date of PA denial to file an internal appeal. For urgent cases, an expedited internal appeal must be decided within 3 business days of receipt.

External Review Process

If the internal appeal is denied, the patient or provider can request an external review through the Wisconsin Office of the Commissioner of Insurance. The OCI conducts an independent review of the PA denial.
