Last reviewed and updated: August 2026 by a licensed Canadian physician

Insurance companies require specific medical documentation to process claims. Here's what you need and how to get it without waiting weeks for an appointment.

Why Insurance Companies Require Doctor's Notes

Insurance claims require New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time. to verify that your claim is legitimate. Without proper documentation, your claim will be delayed or denied, regardless of how valid it is. Having a proper doctor's note protects your job, your income, and your peace of mind during a stressful time.

When you are dealing with an illness or injury, the last thing you want is to fight with an insurance company over a technicality. Insurance providers process thousands of claims daily, and they rely on standardized medical evidence to approve payouts. A comprehensive medical note serves as the undeniable proof that your condition is real, severe enough to warrant time off, and requires specific accommodations or compensation.

Different types of insurance claims require different documentation, and understanding these nuances can mean the difference between a swift approval and a frustrating denial.

Types of Insurance Claims Requiring Medical Notes

1. Travel Insurance Claims

If you need to cancel a trip or seek medical treatment while travelling, the requirements are strict. Travel insurance companies are notoriously meticulous about documentation.

| Situation | Documentation Needed |
|-----------|---------------------|
| Trip cancellation (illness before travel) | Note confirming illness prevents travel |
| Trip interruption (illness during travel) | Note from treating physician + receipts |
| Medical emergency abroad | Hospital records + physician notes |
| Pre-existing condition flare-up | Note confirming unexpected worsening |

Key requirement: The note must confirm the condition arose AFTER purchasing insurance (unless pre-existing conditions are covered). Without this explicit confirmation, your claim is almost guaranteed to be rejected.

2. Short-Term Disability (STD) Claims

Short-term disability claims are designed to replace a portion of your income when you cannot work due to a non-work-related illness or injury. These claims require robust medical evidence.

| Requirement | Details |
|-------------|---------|
| Initial claim | Physician note confirming inability to work |
| Diagnosis | Must be included (unlike employer notes) |
| Functional limitations | What you cannot do |
| Expected duration | When you might return to work |
| Treatment plan | What treatment you're receiving |
| Follow-up notes | Usually every 2-4 weeks |

Failing to provide a detailed note for an STD claim can result in immediate suspension of your benefits, leaving you without income when you need it most.

3. Long-Term Disability (LTD) Claims

LTD claims require more extensive documentation because the financial stakes are much higher for the insurance company. They need absolute certainty about your condition.

  • Detailed medical history

  • Specialist reports (if applicable)

  • Functional capacity evaluation

  • Treatment records

  • Physician statement of disability


4. Critical Illness Insurance

Requires confirmation of a qualifying diagnosis from a licensed medical professional:

  • Cancer diagnosis with pathology report

  • Heart attack with cardiac enzyme results

  • Stroke with imaging confirmation

  • Other qualifying conditions per policy


5. Accident/Injury Claims

Whether it is a motor vehicle accident or a slip and fall, accident claims demand precise documentation:

  • Date and circumstances of injury

  • Diagnosis and severity

  • Treatment provided

  • Prognosis and recovery timeline

  • Functional limitations


What Makes a Good Insurance Doctor's Note

Insurance companies are looking for specific elements. A vague "patient is sick" note will be rejected immediately. You need a document that leaves no room for interpretation.

Must Include:


1. Patient full legal name and date of birth
2. Date of examination/assessment
3. Diagnosis (ICD-10 code helpful but not required)
4. Date of onset, when symptoms began
5. Functional limitations, what the patient cannot do
6. Treatment plan, medications, therapy, referrals
7. Prognosis, expected recovery timeline
8. Physician credentials, name, registration number, signature
9. Clinic/practice information, address, phone number

Common Reasons Claims Are Denied:


  • Note is too vague ("patient is unwell")

  • Missing diagnosis or onset date

  • No functional limitations described

  • Note doesn't match policy's definition of disability

  • Documentation submitted too late

  • Gaps in treatment records


Tips for Successful Insurance Claims

1. Document Early


Start getting medical documentation as soon as your condition begins. Gaps in treatment records are massive red flags for insurers. Do not wait until you feel better to try and get a note retroactively.

2. Be Specific


Vague notes get denied. Your doctor should describe exactly what you cannot do and why. If you cannot sit for more than 30 minutes, the note must state that clearly.

3. Match Policy Language


Read your policy's definition of "disability" or "illness" and ensure your documentation addresses those specific criteria. Insurance adjusters look for keywords that align with their internal guidelines.

4. Keep Copies


Always keep copies of all medical documentation submitted to insurers. Things get lost in the mail or digital ether, and having a backup is crucial.

5. Follow Up


If your insurer requests additional information, respond promptly. Delays can result in claim closure, forcing you to start the arduous process all over again.

MedLetter vs Walk-in Clinics

When you need a sick note for an insurance claim, you have choices. However, the traditional route is often fraught with frustration.

If you go to a standard walk-in clinic, you can expect to wait anywhere from 2 to 4 hours in a room full of other sick people. Once you finally see a doctor, you will likely be charged a fee ranging from $20 to $50 just for the note, on top of the time you have already wasted.

With MedLetter, the process is entirely different. For a flat fee of $49, you get a comprehensive, legally valid sick note from a licensed Canadian physician delivered the same day. There are no waiting rooms, no exposure to other illnesses, and no hidden fees. It is the fastest, most efficient way to secure the documentation you need to protect your job and your insurance claim.

Important: Timing for Travel Insurance

For travel insurance claims, timing is absolutely critical:

  • You must have purchased insurance BEFORE the medical condition arose

  • Documentation must show the condition was unexpected

  • Pre-existing conditions are typically excluded unless you purchased a waiver

  • Get your note as close to the onset of illness as possible
