Health Insurance Claim Denied in Montréal? Here's How to Appeal

Montréal is Canada's second-largest city and the heart of Québec's health system. The province operates the Régie de l'assurance maladie du Québec (RAMQ) — Québec's public health insurance plan — which covers all residents for medically necessary physician and hospital services. But for dental, vision, prescription drugs, paramedical services, and private hospital rooms, residents rely on private supplemental (group or individual) insurance. When that private coverage is denied, Montréal residents have a specific set of rights under Québec's insurance legislation.

RAMQ and the Role of Private Insurance

RAMQ is mandatory for all Québec residents and covers core medical services: physician visits, hospital stays, and insured diagnostic tests. However, RAMQ does not cover prescription drugs for anyone who has access to private group insurance through their employer. This is a critical feature of Québec's system: employees with access to employer drug coverage are legally required to use it rather than the public RAMQ drug plan. This means private insurer drug benefit denials in Montréal are extremely consequential — they cannot simply be redirected to RAMQ.

Beyond drugs, RAMQ does not cover dental care (except for limited categories of children and social assistance recipients), vision care, private hospital rooms, ambulance fees, or paramedical services. Private extended health insurance fills these gaps, and denial of these benefits is where most Montréal claim disputes originate.

Montréal's Major Private Insurers

Blue Cross Québec (Canassurance Hospital Service Association) is one of Québec's largest individual and group health insurers, with deep roots in Montréal's francophone community.

SSQ Insurance (now part of Beneva following its merger with La Capitale) is a major Québec-based insurer with a large employer group plan market in Montréal.

Desjardins Assurances — part of the Desjardins financial cooperative group, headquartered in Lévis but with a massive presence in Montréal — offers both group and individual extended health products.

Manulife, Sun Life, and Canada Life (Great-West Life) are the major national insurers active in Montréal's group benefits market.

Major Montréal hospitals include McGill University Health Centre (MUHC) — comprising Royal Victoria Hospital and Montréal General Hospital on the Glen campus — and the Centre hospitalier de l'Université de Montréal (CHUM) on Saint-Denis. Both are major tertiary referral centres. Private clinics supplement the public system for faster access to certain procedures.

Common Reasons Claims Are Denied in Montréal

Drug benefit denials. Because Québec's mandatory drug plan creates an obligation on employers to offer drug coverage, private drug plan denials in Montréal are high-stakes. Common denial reasons include formulary exclusions (the drug is not on the plan's approved list), step therapy requirements (the plan requires trying a cheaper drug first), and quantity limits.

Dental and orthodontic denials. Dental plans have annual maximums, orthodontic lifetime maximums, and waiting periods. Claims for major restorative work (crowns, bridges, implants) are frequently subject to benefit verification disputes and pre-authorization requirements.

Paramedical service limits. Physiotherapy, chiropractic, massage therapy, and psychotherapy are covered by most extended health plans but with strict annual visit limits. Exceeding these limits is the most common denial reason.

Mental health and psychotherapy. Access to psychologists and psychotherapists is expensive in Montréal, and private plan limits are often quickly exhausted. Claims may also be denied when a provider is not recognized under the plan's eligible provider list.

Pre-existing condition exclusions. Individual insurance products (as opposed to group plans) typically exclude pre-existing conditions for a defined period — often two years. New Montréal residents or those buying individual coverage after losing group coverage frequently encounter these exclusions.

Your Rights Under Québec Law

Québec's insurance industry is regulated by the Autorité des marchés financiers (AMF). The AMF oversees both life and health insurance and general insurance in Québec. All insurance policies in Québec are also governed by the Civil Code of Québec, which requires contracts to be interpreted in favour of the insured when ambiguous.

The Chambre de l'assurance de dommages (ChAD) and the Chambre de la sécurité financière (CSF) regulate insurance advisors and brokers. If your broker gave you incorrect advice about your coverage, these bodies can receive complaints.

The Ombudsman for Life and Health Insurance (OAQ — Ombudsman des assurances de personnes) — known as the OmbudService for Life & Health Insurance (OLHI) in English — is the industry-funded independent dispute resolution service for life and health insurance in Canada, including Québec. This is your primary external escalation pathway for denied extended health claims.

The Appeals Process

Step 1: Internal Grievance. Every insurer operating in Québec must have an internal complaints process. Submit your appeal in writing to your insurer's customer relations or complaints department. Include your policy number, the claim details, supporting documentation (receipts, prescriptions, provider notes), and a clear argument for why the denial is incorrect.

Step 2: Autorité des marchés financiers (AMF). If the insurer does not resolve your complaint satisfactorily, you can file a complaint with the AMF at lautorite.qc.ca. The AMF reviews insurers' compliance with Québec insurance legislation.

Step 3: OmbudService for Life & Health Insurance (OLHI/OAQ). For an independent review of your specific claim, contact the OLHI at olhi.ca or call 1-888-295-8112. The OLHI provides free, impartial dispute resolution. Most major insurers — including Blue Cross Québec, Beneva, Desjardins, Manulife, and Sun Life — participate in the OLHI scheme.

Practical Tips for Montréal Residents

• Drug denials: If a drug is denied because it is not on your plan's formulary, ask your prescribing physician to write a letter explaining why the formulary alternative is not appropriate for your condition. This is the basis for a medical exception request.
• Pre-authorization: For dental procedures over a certain threshold, most plans require Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization. Get this before treatment, not after.
• Bilingual correspondence: In Québec, you have the right to communicate with insurers in French. All policy documents must be available in French. If your denial letter was only in English, request the French version.
• AMF complaint procedure: Insurers must acknowledge AMF-referred complaints within a specific timeframe. AMF involvement often accelerates internal resolution.
