How Long Does an Insurance Appeal Take? Country-by-Country Guide
Timeline guide for insurance appeals by country, including internal and external review deadlines.
You've filed your appeal. Now you're waiting. How long will this take? The answer depends on your country, your insurer, and whether your case is urgent. This guide gives you exact timelines by country and appeal level, plus what to do when the insurer is dragging its feet.
erisa-and-aca-plans">United States: ERISA and ACA Plans
| Stage | Your Filing Deadline | Insurer's Decision Deadline |
|---|---|---|
| Internal appeal — urgent care | — | 72 hours |
| Internal appeal — pre-service | — | 30 days |
| Internal appeal — post-service | — | 60 days |
| External independent review | 4 months from final denial | 45 days (standard); 72 hours (expedited) |
For Medicare, the timeline runs:
- Redetermination (Level 1): Decision within 60 days
- QIC Reconsideration (Level 2): Decision within 60 days
- ALJ Hearing (Level 3): Typically 90 days, often longer in practice
- Medicare Appeals Council (Level 4): 90 days
- Federal Court (Level 5): No set deadline
Expedited appeals for urgent cases: If your doctor certifies that standard timelines would seriously jeopardize your health, the insurer must decide within 72 hours (internal) and 72 hours (external review).
United Kingdom: FCA Complaint Process
The UK complaint process is among the most consumer-friendly in the world:
- Insurer acknowledgment: Within a "reasonable time" (usually 5 business days)
- Final Response: Within 8 weeks of your formal complaint
- Financial Ombudsman Service (FOS): If no Final Response within 8 weeks, or if the Final Response is unsatisfactory, refer to FOS within 6 months of the Final Response
FOS investigation typically takes 3–6 months for straightforward cases and 6–18 months for complex disputes. The FOS upholds approximately 35–40% of insurance complaints formally — with many more resolved informally before a decision.
Australia: AFCA Process
- Insurer IDR response: Within 30 calendar days of your complaint under ASIC's RG 271 standard (extended for complex cases with written notice to you)
- AFCA referral stage: Most complaints are resolved within 30–60 days of lodging with AFCA
- AFCA case management: Cases that proceed beyond referral typically resolve within 3–6 months
- AFCA formal determination: 6–12 months for complex cases
Key AFCA fact: Approximately 70% of AFCA insurance complaints are resolved at the referral or early resolution stage. Simply lodging with AFCA often prompts insurers to settle.
Singapore: MAS / FIDReC Process
- Insurer acknowledgment: Within 5 business days
- Insurer final response: Within 21 working days
- FIDReC mediation: If lodged, typically 2–4 months for mediation resolution
- FIDReC adjudication: 4–12 months for complex cases
FIDReC resolves more than 85% of cases at the mediation stage — the highest rate of any major insurance dispute body globally.
Malaysia: BNM / OFS Process
- Insurer acknowledgment: Within 5 working days
- Insurer resolution: Within 14 calendar days (extendable to 30 working days for complex cases)
- OFS mediation: Typically 2–4 months
- OFS adjudication: 6–12 months for complex cases
You may file with OFS after receiving the insurer's final response, or after 60 days without a substantive response.
Canada: Provincial Regulators and OLHI/DRO
- Insurer internal response: Varies by province; typically 30–60 days
- OmbudService for Life and Health Insurance (OLHI): Free independent review; typically 2–4 months
- Insurance Bureau of Canada Ombudsman (for property and casualty): Similar timelines

How to Speed Up Your Appeal
Request a peer-to-peer review. In the US, request a peer-to-peer conversation between your treating physician and the insurer's medical director. Many US insurers flip decisions within 48 hours after a physician-to-physician discussion.
Call the appeals department after filing. Confirm receipt and ask for the assigned reviewer's contact. "I submitted appeal [number] on [date]. Can you confirm receipt? When should I expect a decision?" A phone call often moves things along.
Escalate early if the insurer misses its deadline. In the US, if the insurer misses its internal decision deadline, you may be deemed to have exhausted internal remedies and can proceed to external review. In the UK, if there is no Final Response within 8 weeks, you can go to FOS. Don't wait indefinitely.
Don't accept extensions without pushing back. If the insurer requests more time, ask specifically why, provide any additional requested information immediately, and ask for a firm decision date.
Red Flags: When to Escalate Immediately
Even if the insurer hasn't missed a deadline, escalate if:
- The insurer requests the same information twice (a common stalling tactic)
- The insurer gives contradictory or shifting reasons for the denial
- The appeals department is unresponsive to written follow-up requests
- The insurer suggests the appeal is unlikely to succeed — this itself may indicate bad faith
Overall Timeline Expectations
- Minimum (everything goes smoothly): 4–6 weeks
- Typical: 2–4 months (internal + external review or ombudsman)
- Complex cases: 4–8 months
- Worst-case (full legal process): 8–18+ months
Plan your finances and medical care around 2–4 months. If it resolves faster, that is a bonus.
