No-Fault Benefit Denials: How to Challenge and Appeal

September 23, 2025, Kitchener, Ontario

Posted by: Robert Deutschmann, Personal Injury Lawyer

Denials and delays happen in Ontario auto-no-fault claims. A systematic, evidence-driven approach can turn a denial into a funded benefit. Deutschmann de Koning Law brings deep Ontario expertise to every step, helping you secure what you’re owed.

Why denials happen

1. Medical necessity and reasonableness debates: Insurers often question whether a treatment is necessary or appropriate for your injuries.
2. Documentation gaps: Missing or incomplete records can create openings for denial or reduced benefits.
3. Network and coverage issues: Claims may be challenged if services fall outside approved networks or benefit scopes.
4. Administrative missteps: Errors in forms, deadlines, or communications can derail a claim.
5. Evolving medical information: As your condition changes, insurers may reassess and deny or limit benefits based on new medical data.

Appeal process overview

Start with internal reconsideration: When a denial occurs, you typically begin with a reconsideration or appeal with your insurer.

1. Escalate to formal dispute channels: If the outcome is unfavourable, Ontario provides regulated dispute avenues through regulators or designated panels.
2. Timelines are critical: Deadlines are strict; acting promptly is essential to preserve eligibility and leverage your rights.
3. Our approach keeps you moving: We coordinate every step, ensuring submissions are complete, timely, and strategically aligned with your recovery goals.

What evidence helps support an appeal

1. Updated medical records: Ongoing evaluations and clear progress notes demonstrate medical necessity and continuity of care.
2. Detailed treatment histories: A chronology showing what was prescribed, why it was needed, and how it advances recovery.
3. Clinician letters explaining necessity: Treating physicians can articulate why specific therapies are essential, supported by medical rationale.
4. Impact on daily life and work: A clear narrative of how injuries affect activities, mobility, and earning capacity strengthens your case.
5. Expert opinions when needed: Independent medical or rehabilitation experts can be persuasive for contested therapies or extended care.
6. Organisation and clarity: A well-structured package with highlights, evidence summaries, and easy cross-referencing makes review easier for decision-makers.
