External review

This state operates an external review process that meets federal standards, per KFF. Your final denial notice names who handles it. For some plans, including self-funded employer plans, a federal process applies instead.

Before you file

1. Appeal to the insurer first and keep copies; a complaint does not stop appeal or lawsuit deadlines.
2. Check whether your plan is state-regulated: self-funded employer plans are usually outside state jurisdiction.
3. Use the complaint summary letter to organize your answers, then use the department's own form.
