Your Legal Rights in Maine

Maine Bureau of Insurance

The Maine Bureau of Insurance regulates Anthem Blue Cross Blue Shield for fully-insured plans in Maine.

• Superintendent: Eric Cioppa
• Phone: (207) 624-8475
• Website: https://www.maine.gov/pfr/insurance/
• External review: Yes — available through the Maine Bureau of Insurance for fully-insured plans

File a complaint with the Maine Bureau of Insurance if Anthem BCBS is not following required appeal timelines, is providing inadequate denial explanations, or is failing to maintain adequate provider networks for Maine's rural communities.

Maine State Statutes and Appeal Deadline

Maine has enacted meaningful health insurance consumer protections:

• Maine Insurance Code Title 24-A: Requires health insurers to comply with utilization review standards, provide complete denial explanations, and honor appeal rights.
• Maine External Review Law (24-A M.R.S. § 4311 through § 4326): Provides the right to independent external review for adverse determinations based on medical necessity or experimental treatment grounds. External review decisions are binding on Anthem.
• Maine Community Rating: Maine requires individual and small group health plans to use modified community rating, meaning Anthem cannot charge you more based on your health status or history. This also means Anthem must maintain broader coverage for existing conditions.
• Maine Mental Health Parity (24-A M.R.S. § 2749-B): Requires Anthem to cover mental health and substance use disorder treatment at parity with medical and surgical benefits. Maine has an active enforcement record.
• Network Adequacy: Anthem must meet Maine network adequacy standards, which can be challenging in rural areas. If you cannot access an in-network provider in a timely manner, this supports a claim for out-of-network coverage at in-network rates.

Your internal appeal deadline is 180 days from the date on the denial letter. Expedited review for urgent medical situations requires Anthem to respond within 72 hours.

Federal Protections That Apply

• ACA: Internal appeal and external review rights for non-grandfathered plans
• ERISA: For employer-sponsored plans — claims file access, full and fair review, and federal court review
• Mental Health Parity Act (MHPAEA): Federal floor for mental health coverage equality
• No Surprises Act: Protection from unexpected bills for emergency and out-of-network services

Documentation Checklist for Your Appeal

• Denial letter with specific reason and Anthem BCBS policy citation
• Your EOB showing how the claim was processed
• Complete medical records documenting diagnosis and treatment history
• Physician letter explaining medical necessity with specific clinical justification
• For network adequacy issues: documentation that no in-network provider was available in your area within a reasonable time and distance
• For mental health denials: evidence that Anthem applied stricter criteria than for comparable medical/surgical claims (24-A M.R.S. § 2749-B parity argument)
• Clinical guidelines from relevant medical associations
• Anthem's clinical policy bulletin for the denied treatment (request from Anthem)
• Your plan's Summary of Benefits and Coverage or Certificate of Coverage

Step-by-Step: Appeal Your Anthem BCBS Denial in Maine

Step 1: Read the denial letter carefully. Identify the exact denial reason and the Anthem clinical policy cited. Request your complete claim file including the reviewer's notes and the full clinical policy document.

Step 2: Assess network adequacy arguments. Maine's rural geography is a legitimate basis for network adequacy appeals. If no in-network specialist could serve your area in a reasonable timeframe, document this thoroughly.

Step 3: Request peer-to-peer review. Your physician can call Anthem Maine to speak directly with the medical director. Maine regulations require timely scheduling, and many denials are reversed at this stage.

Step 4: Write your internal appeal. Reference your Anthem BCBS member ID, claim number, and denial date. Address each denial criterion with specific clinical evidence. Cite Maine Insurance Code and applicable federal law. For mental health denials, invoke 24-A M.R.S. § 2749-B. Include your physician's letter.

Step 5: Submit and document. Send via certified mail and through the Anthem member portal. Keep copies with delivery confirmation and track response deadlines.

Step 6: Escalate if the internal appeal is denied. Contact the Maine Bureau of Insurance at (207) 624-8475 to request external independent review. The IRO's decision is binding on Anthem. File a formal complaint simultaneously if Anthem violated state procedural requirements or community rating rules.
