Internal Appeal Deadline

180 days

You typically have 180 days from the date of denial to request an internal appeal with Maine insurers.

This is your first step — submit your appeal in writing with additional clinical evidence, documentation, and a clear explanation of medical necessity. Keep copies of everything you send.

External Review Process

Maine allows external review of denied claims. If your internal appeal is denied, you can request an independent review by a physician or medical professional who was not involved in the initial denial decision.

An external reviewer will look at your case afresh and make a binding recommendation. This is often successful for medical necessity denials because the external reviewer focuses on clinical evidence, not cost.

State Department of Insurance Complaint

If your internal appeal and external review are both unsuccessful, or if your insurer is not following proper appeal procedures, you can file a complaint with the Maine Department of Insurance.

Your state's insurance commissioner can investigate violations of insurance law and order insurers to overturn denials or pay penalties.
