Insurance Claim Denied in New Brunswick? How to Appeal

New Brunswick is Canada's only officially bilingual province, and its insurance landscape reflects a mix of provincial public health coverage and private supplemental insurance. When a claim is denied — whether through NB Medicare, a private health plan, or a group benefit plan — knowing the provincial rules and escalation pathways is essential to getting it reversed. New Brunswick policyholders have access to free dispute resolution through provincial and national ombudsman services, making it practical and low-cost to challenge unfair denials at every stage. This guide explains your rights and what steps to take.

Why Claims Are Denied in New Brunswick

Insurance denials in New Brunswick fall into two broad categories depending on whether the coverage is provincial or private:

• NB Medicare denials — Services deemed not medically necessary under the Medical Services Payment Act (RSNB 1973, c. M-7), services provided by non-enrolled providers, non-covered services such as cosmetic procedures, and billing errors or missing referral documentation.
• Private health insurance denials — Pre-existing condition exclusions during waiting periods, "not medically necessary" determinations by plan administrators, Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization failures, out-of-network provider restrictions, benefit exhaustion (annual or lifetime limits reached), and disability insurance denials based on own-occupation versus any-occupation criteria under the plan's definition of disability.
• Group benefit plan denials — Employer-sponsored group benefit denials for dental, vision, paramedical services, or short-term and long-term disability benefits, governed by the plan's Evidence of Coverage and provincial or federal law depending on plan structure.
• Drug plan gaps — The New Brunswick Drug Plan covers eligible seniors and social assistance recipients, but most working-age adults rely on private coverage. Formulary exclusions, prior authorization failures, and quantity limits are common denial grounds.

How to Appeal

Step 1: Read the Denial Letter and Identify the Specific Ground

Whether from NB Medicare or a private insurer, the denial must state the specific reason. Under the Insurance Act (RSNB 1973, c. I-12) and the Financial and Consumer Services Commission of New Brunswick's (FCNB) regulatory standards, vague denial notices are non-compliant. Identify whether the denial is based on: (a) a coverage exclusion, (b) a medical necessity determination, (c) a prior authorization failure, or (d) a technical billing issue. Each requires a different strategy and different supporting documentation.

Step 2: Gather Your Full Documentation Package

Collect the denial letter with the specific reason and policy clause cited, the full policy document or benefit booklet including definitions and exclusions, your treating physician's letter of medical necessity with the relevant diagnosis codes, medical records supporting the claim, clinical guideline citations from applicable professional bodies (such as the Canadian Cardiovascular Society, Diabetes Canada, or Canadian Cancer Society) where the treatment is a recognized standard of care, and all prior correspondence with the insurer dated chronologically.

Step 3: File a Formal Internal Appeal with the Insurer

Submit a written appeal to the insurer's appeals department within the applicable deadline — typically 90 to 180 days from the denial date for private plans. Include your physician's letter, clinical guideline citations, and a direct rebuttal of each stated denial reason. Request a written acknowledgment with a reference number. Most major Canadian insurers are members of the Canadian Life and Health Insurance Association (CLHIA) and are expected to follow CLHIA fair claims-handling guidelines.

Step 4: Escalate to the Insurer's Internal Ombudsman

Most major insurers in Canada have an internal ombudsman or senior review process above the first-level appeals department. If the first-level appeal fails, escalate to this level in writing before going to external bodies. This creates a documented record and is often required before external ombudsman bodies will accept your complaint.

Step 5: File with OLHI or GIO for External Dispute Resolution

For life, disability, or health insurance disputes, file a complaint with the Ombudservice for Life and Health Insurance (OLHI) at olhi.ca after exhausting internal appeals. OLHI provides free, independent review and makes recommendations to member insurers — most major Canadian life and health insurers are OLHI members. For property or casualty insurance disputes, contact the General Insurance OmbudService (GIO) at gio-bga.ca.

Step 6: File a Regulatory Complaint with FCNB

For provincially incorporated insurers operating in New Brunswick, file a formal complaint with the Financial and Consumer Services Commission of New Brunswick at fcnb.ca, or call 1-866-933-2222. The FCNB can investigate regulatory violations and improper claims-handling practices. For federally incorporated insurers, contact the Financial Consumer Agency of Canada (FCAC) or OSFI.
