Your Legal Rights in New Hampshire

Federal Protections That Apply to All New Hampshire Residents

ACA §2719 (Affordable Care Act) requires non-grandfathered health plans to offer at least one level of internal appeal and access to external independent review. Aetna must provide written denial notices specifying the reason, the clinical criteria applied, and instructions for filing an appeal.

ERISA §1133 (Employee Retirement Income Security Act) applies to employer-sponsored self-funded plans. Under ERISA §1133, Aetna must give you written notification of the denial reason, allow access to your complete claims file, and provide a full and fair review. If the appeal fails, ERISA §502(a) allows federal civil action to recover benefits.

Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA §1185a (Mental Health Parity and Addiction Equity Act) requires that Aetna cover mental health and substance use disorder services on no more restrictive terms than comparable medical and surgical benefits. New Hampshire has state mental health parity requirements under RSA 417-E. If a behavioral health claim was denied, request a comparative analysis of Aetna's review criteria.

Step-by-Step: How to Appeal Your Aetna Denial in New Hampshire

Step 1: Analyze the Denial Carefully

Under ACA §2719 and RSA 420-J, Aetna's denial letter must state the specific reason for denial, the plan provision or clinical guideline applied, and your appeal rights and deadlines. Read every line. Note all stated denial reasons — each requires a direct response in your appeal.

Request your complete claims file from Aetna. This includes reviewer notes, the Clinical Policy Bulletin applied, and all documentation Aetna considered. You are entitled to this information under both federal law and RSA 420-J.

Step 2: Build Your Documentation Package

Before writing the appeal, gather:

• Full denial letter including denial codes
• Medical records specific to the denied service
• Treating physician's detailed letter of medical necessity (on letterhead, signed)
• Lab results, imaging reports, and specialist consultation notes
• Aetna's Clinical Policy Bulletin for the denied treatment
• Clinical practice guidelines from the relevant medical specialty society
• Prior treatment records if step therapy is cited
• Documentation of the medical circumstances if emergency or out-of-network care is at issue
• Prior authorization records if applicable

Step 3: Draft a Focused Appeal Letter

Your appeal letter must directly address every denial reason with corresponding evidence. Include your Aetna member ID, claim number, date of service, and denial date. Cite ACA §2719, ERISA §1133 (for employer plans), MHPAEA §1185a and RSA 417-E (for behavioral health denials), and RSA 420-J (for managed care plan issues). State the specific outcome you want and provide a deadline for Aetna's response.

Step 4: Request Peer-to-Peer Review

Ask your treating physician to request a peer-to-peer review directly with the Aetna medical director who denied the claim. Under RSA 420-J, managed care organizations must accommodate such requests. Your doctor can present clinical details that may not be adequately captured in written records. Many denials are resolved at this stage.

Step 5: Submit the Appeal

• Submit via certified mail with return receipt to Aetna's appeals address on the denial letter
• Also submit through the Aetna member portal at aetna.com
• Keep copies of all materials with delivery confirmation
• Standard response deadline: 30 days; urgent/expedited: 72 hours

Step 6: Request External Review If the Internal Appeal Fails

If Aetna upholds the denial, immediately request external review through the New Hampshire Insurance Department under RSA 420-J. Contact the NHID at nh.gov/insurance or call (603) 271-2261. An independent IRO physician reviews your case. The decision is binding on Aetna and free to you. External reviews overturn 40–60% of insurance denials.

File a regulatory complaint with the NHID if Aetna violated timeframes, provided inadequate denial explanations, or violated RSA 417-A's unfair claims settlement practices.

Step 7: Legal Action for High-Value Claims

For large or complex denials, consult an insurance appeal attorney in New Hampshire. ERISA §502(a) provides a federal cause of action for employer plan members. New Hampshire state law provides remedies for bad faith insurance conduct under RSA 417-A.
