When an insurance company denies your claim in New Hampshire, you have the right to appeal internally and pursue legal action if the denial was unreasonable or made in bad faith. New Hampshire’s regulatory framework and case law provide multiple avenues for recovery, and the state’s courts take policyholder protections seriously.

This guide explains New Hampshire’s claims appeal process, the statutory and common law standards for bad faith, and how to recover damages if your insurer acted improperly. Understanding your rights under New Hampshire law is critical to challenging improper denials and holding insurers accountable.

Reasons Insurance Companies Deny Claims

New Hampshire insurers deny claims citing policy exclusions, coverage disputes, alleged misrepresentation or non-disclosure, breach of policy conditions, and disagreements over causation or damages valuation. Common reasons include claims for pre-existing conditions not disclosed, losses occurring before the policy effective date, or damage allegedly falling outside covered perils. However, New Hampshire law requires that any denial be based on reasonable investigation and legitimate interpretation of policy terms.

Your Right to Appeal a Denied Claim in New Hampshire

Step 1 — Internal Appeal

You have 15 business days from the denial notice to submit an internal appeal. Send your appeal request in writing to your insurance company’s claims department. Include comprehensive supporting documentation: medical records, repair estimates, photographs, witness statements, expert reports, policy excerpts, and legal arguments explaining why the denial is improper. The insurer must conduct a thorough review and provide a written response.

Step 2 — External / Independent Review

For health insurance claims, New Hampshire provides an external review process for denials based on medical necessity or experimental treatment determinations. File your external review request with the New Hampshire Department of Insurance. The independent reviewer will conduct an objective evaluation. The external review decision is binding on the insurer.

Step 3 — File a Complaint with the New Hampshire Department of Insurance

If the insurer denies your internal appeal without reasonable justification or violates New Hampshire law, file a complaint with the Department of Insurance. Include your denial letter, internal appeal request, the insurer’s response, and a detailed explanation of your complaint. The Department investigates consumer complaints and may take enforcement action against insurers that improperly deny claims.

Bad Faith Insurance in New Hampshire

New Hampshire addresses bad faith through both statute and common law. NH RSA § 417:4 prohibits unfair claims practices, including misrepresentation, failure to acknowledge communications, failure to conduct reasonable investigation, unreasonable delay, and refusal to pay without reasonable basis. Violations of this statute expose insurers to liability.

New Hampshire courts also recognize common law bad faith claims. Bad faith occurs when an insurer acts in a manner that violates the implied covenant of good faith and fair dealing in insurance contracts. This includes failure to investigate reasonably, ignoring favorable evidence, misrepresenting policy terms, and denying claims without legitimate basis. The common law standard emphasizes that insurers must exercise their discretion reasonably and in good faith.

If you prove bad faith under either the statute or common law, you are entitled to recover actual damages (the claim amount plus out-of-pocket costs), attorney fees, and costs. The combination of statutory and common law protections provides multiple avenues for holding insurers accountable for improper denials.

Real Situations in New Hampshire

Manchester, New Hampshire — Homeowners Insurance Denial Margaret’s home suffered damage from a winter storm. The insurer denied the claim, arguing the damage resulted from “poor maintenance” rather than the storm. The insurer conducted no site inspection, obtained no weather records, and consulted no engineers. Margaret obtained a structural engineer’s report documenting that all damage was consistent with the storm. She filed a bad faith complaint citing the insurer’s failure to conduct reasonable investigation under § 417:4. The insurer settled for the full claim amount plus additional damages.

Portsmouth, New Hampshire — Auto Insurance Denial Jeffrey submitted medical payment claims to his auto insurer following a car accident. The insurer denied the claims within days without reviewing his medical records or contacting his healthcare providers. New Hampshire law requires reasonable investigation, and this conduct fell short. Jeffrey’s attorney sent a demand letter citing § 417:4 violations and common law bad faith. The insurer reversed the denial and paid the claims plus attorney fees.

Concord, New Hampshire — Health Insurance Denial Patricia’s thyroid condition treatment was denied by her health insurer as not medically necessary. The insurer’s brief denial letter provided no medical justification and ignored her physician’s treatment plan. Patricia requested external review through the Department of Insurance. The external reviewer determined the treatment was medically necessary. Patricia also filed a bad faith complaint alleging the insurer violated § 417:4 with its unjustified denial.

Common Mistakes New Hampshire Policyholders Make

Missing the 15-business-day appeal deadline: This window is critical for preserving your claims and strengthening later arguments. Submit your appeal in writing well before expiration.
Not requesting the insurer’s investigation file: Write to the insurer requesting all investigation notes, expert reports, communications, and the basis for denial. This documentation is crucial evidence in bad faith claims.
Failing to cite § 417:4 in appeals and demand letters: Including specific references to New Hampshire’s unfair claims practices law demonstrates you understand your statutory rights.
