Doctor First Report

When a worker comes to you with a workplace injury, the Doctor First Report is how WCB Manitoba learns what happened and what the worker can do. The claim decision and any wage loss benefits lean on your diagnosis and your answers about time off and modified work, so vague work capabilities are the part most likely to stall a claim.

What the Doctor First Report is for

WCB Manitoba uses this report to decide whether an injury arose from work and what benefits and treatment follow. WCB’s own fee policy calls it the Doctor Initial Report, Form 4, and the form carries a large 4 in its header. It’s often mixed up with the Manitoba Public Insurance report for motor vehicle injuries. When a worker is hurt driving for work, ask which insurer the claim is with before you choose the form.

Who completes it

The physician who examines the worker completes the whole report, including the worker’s own account of the incident in their words. There’s no part for the worker or the employer to fill in.

How to fill in the report

Worker and employer information

Enter the worker’s name, address, phone, date of birth, gender, weight, height, job title and PHIN, and the claim number if the worker has one. Give the employer’s name and the branch address where the worker is based. The job title lets WCB and the employer compare your restrictions with the work the worker normally does.

Injury details

Give the date of the incident and the area of injury, then the worker’s description of what happened. Record the mechanism as the worker tells it. A clear account helps WCB connect the injury to the work activity.

Examination findings and diagnosis

Enter the examination date, ICD code and diagnosis, then subjective complaints and objective findings. The form asks for range of motion, muscle testing and neurological status, so record measured findings as well as tenderness. Describe any pre-existing condition that may affect recovery, and list tests performed with location and date, attaching results.

Treatment plan

Describe the treatment, medications and referrals, and give the date of the next visit. A next visit date tells WCB when to expect a progress report.

Work capabilities

Say whether the worker will be off work beyond the day of the incident and when they can return to regular duties, or that it’s unknown at the time of the exam. If they can do alternate or modified work, outline the restrictions in functional terms, such as lifting limits or no use of one hand, and give their duration in weeks. “Light duties” alone gives the employer nothing to plan around.

Physician information

Print your name, address, phone and fax, sign and date the report.

  • No ICD code or diagnosis.

Questions

Questions we hear a lot.

What's the difference between the Doctor First Report and the Doctor Progress Report?

The first report goes in after your first visit for the injury and records the incident, employer and initial findings. The progress report follows later visits and asks whether the diagnosis has changed, whether recovery is satisfactory and whether you've referred to a consultant.

Where do I send the Doctor First Report?

Fax it to WCB Manitoba at 204-954-4999 in Winnipeg or 1-877-872-3804 toll free. Both numbers are printed on the form.

Does WCB Manitoba pay for the report?

Yes. WCB pays a reporting fee for the Doctor First Report, at the rate set in its agreements with Doctors Manitoba.

Can a chiropractor use this form?

No. Chiropractors have their own Chiropractor First Report and Chiropractor Progress Report on the WCB Manitoba forms page, and physiotherapists have their own initial report.

Is patient information secure?

Yes. Medulla has a SOC 2 Type II report from an independent auditor, is HIPAA, PIPEDA, and PHIPA compliant, and is built and hosted in Canada, so patient data stays in the country and never gets pasted into consumer AI tools. Everything is encrypted in transit and at rest. See how we protect patient data.
