Maine Health Insurance Appeals and Grievances

What is an internal appeal?

An internal appeal—often called a grievanceunder your plan's procedure—asks the insurance company to reconsider its adverse health care treatment decision about coverage or payment.

This is different from external review, where the Maine Bureau of Insurance assigns an independent review organization (IRO) after internal appeal is complete (with limited exceptions).

General walkthrough: Appeals roadmap. Maine specifics below.

Maine appeal timelines

24-A M.R.S. §4303 requires carriers to maintain a grievance procedure meeting Bureau standards (read statute):

• Written notice of grievance and external review rights, including Bureau contact information
• Free access to relevant claim files and the right to submit additional evidence
• Standard grievance decisions often within 30 calendar days if you have not requested an in-person appearance before carrier representatives
• Federal Affordable Care Act timelines also apply to many plans for urgent pre-service denials and other appeal types

Exhaustion before external review

Under 24-A M.R.S. §4312(1), you generally must:

• Exhaust all levels of internal grievance for group plans
• Exhaust one level of internal grievance for individual plans

Then you may request Bureau external review within 12 months of the final adverse decision.

When you can skip or shorten internal appeal

Expedited external review may be available without full internal grievance when (§4312(2)):

• The carrier missed required internal appeal deadlines
• You applied for expedited external review at the same time as an expedited internal appeal
• You and the carrier agree to bypass internal grievance
• Life or health is in serious jeopardy, the enrollee has died, or the case involves continued stay after emergency care

How to file

1. Read the adverse decision letter for the appeal address, fax, portal, phone, and deadline.
2. Submit to the carrier using its grievance/appeal form or a clear written request.
3. Request expedited review if hospitalized or at serious health risk.
4. Ask for all claim files—Maine law requires relevant documents free of charge.
5. Keep proof of submission date (certified mail, fax confirmation, portal screenshot).

Evidence that helps

• Treating provider letter explaining medical necessity
• Clinical notes, imaging, lab results, and treatment history
• Plan medical policy or criteria (request from the carrier)
• Peer-reviewed literature for experimental/investigational disputes

MaineCare appeals

MaineCare (Medicaid) uses a fair hearingprocess through DHHS, not the Bureau's commercial IRO program. When MaineCare denies, reduces, or terminates services, your notice explains how to request a hearing—often within 60 days (OMS member resources). Requesting within 10 days may continue services during appeal.

General DHHS hearings: often 30 days from the department notice (Division of Administrative Hearings FAQ)—always follow the deadline on your letter.

MaineCare Member Services: 1-800-977-6740 (TTY 711).

After internal appeal

If the carrier upholds the denial, keep the final adverse health care treatment decision letter—it should describe Bureau external review rights in large, easy-to-read type (§4312(3)).
