Appeal deadlines: what to check before you send anything

Deadlines are one of the most stressful parts of an insurance denial. A letter may mention an appeal deadline, a review period, a complaint process, or a legal right to sue. These are not always the same thing.

Before you send anything, separate the deadlines into categories.

Internal appeal deadline

An internal appeal deadline is the time the insurer gives you to ask it to review its own decision. It might be 30, 60, 90, or 180 days. The letter may say the appeal must be received by the insurer by that date.

This deadline matters because it controls the insurer's review process. If you miss it, the insurer may say the internal review is closed.

Legal limitation period

A legal limitation period is different. It is the deadline for starting a legal claim, if one is available and appropriate. Limitation periods depend on the province, policy, facts, correspondence, and sometimes when a claim was clearly denied.

An internal appeal does not always pause a legal limitation period. If the denial is old, if the amount is significant, or if you are unsure, speak with a lawyer promptly. ClaimCoach North is not a law firm and cannot calculate legal limitation periods for you.

Complaint process deadlines

Some files may involve an ombudservice, regulator, union, employer plan administrator, or government benefit process. Each may have its own rules. A complaint process is not always a substitute for an appeal or legal claim.

Write each process on a separate line. Do not assume one deadline replaces another.

Proof of delivery

If you send an appeal, keep proof. Use email with a sent copy, fax confirmation, courier tracking, portal confirmation, or registered mail. Save the file name, date, and time.

If you send documents by portal, take a screenshot of the confirmation page. If you send by email, include a clear subject line with your name, policy number, claim number, and the word "appeal."

If you need more time

Ask before the deadline. Explain that you intend to appeal and need more time to gather medical or employment documents. Ask for confirmation in writing. If the insurer grants an extension by phone, send a short email confirming what was agreed.

Do not rely only on a voicemail or memory.

A simple deadline table

Create a table with five columns:

1. Deadline type.
2. Date.
3. Where it appears.
4. What must be sent.
5. Proof of delivery.

Example deadline types include internal appeal, medical records request, complaint process, legal advice deadline, and insurer extension request.

Send a complete but focused package

A deadline can pressure you to send everything. Resist the urge to send an unorganized pile of documents. Use a cover letter. List what you are attaching. Explain how each key document answers the reason for denial.

If some evidence will arrive later, say so clearly and ask that the file remain open for it.

Red flags

Get advice quickly if:

• The denial letter is more than a year old.
• The insurer says no further appeal is available.
• You already completed one or more internal appeals.
• You are considering suing.
• You are unsure when the clock started.
• The insurer has used surveillance or credibility language.

The safest approach is to treat every deadline as real until confirmed otherwise.
