What to Do If Your Injury Gets Worse After WorkSafeNB Closes Your File in New Brunswick

If your workplace injury worsens after your WorkSafeNB claim has been closed, you may be entitled to reopen your file. To do so, you must provide compelling new medical evidence from your doctor proving that your current physical complications are directly linked to the original workplace accident.

When you recover from a workplace injury and return to your job in New Brunswick, WorkSafeNB generally closes your active claim file. For many workers, this is the end of a stressful chapter. However, the human body is unpredictable. Sometimes, a severe back strain flares up months later, or a repetitive strain injury sustained in Moncton or Saint John re-emerges with more severe symptoms after you resume your daily duties.

A closed file does not mean you are permanently cut off from the system. 📖 Under the New Brunswick Workers’ Compensation Act, you have the right to request that your claim be reopened if your medical condition significantly deteriorates. Navigating this process, however, requires providing airtight medical proof that your current suffering is not a new injury, but a direct continuation of the old one.

Step-by-Step Process to Reopen a WorkSafeNB Claim in New Brunswick

Reopening a claim is entirely dependent on medical evidence. 📍 You cannot simply call WorkSafeNB and tell them your pain has returned. You must follow a formal process to prove “medical continuity” between your original accident and your current condition.

Step 1: Seek Immediate Medical Attention

The moment your old injury flares up, stop what you are doing and see a doctor. Do not try to tough it out at work, as this can make the injury worse and confuse the timeline. Tell your doctor explicitly that this is an exacerbation of the old workplace injury, not a new accident that happened at home or on the job.

Step 2: Obtain New Medical Evidence

WorkSafeNB will only reopen a file if there is new, objective medical information. 📄 Ask your physician or specialist to complete a detailed medical report. This report must clearly state that your condition has worsened, outline the new physical limitations you are facing, and critically, draw a direct medical link (causation) to the original workplace incident on file.

Step 3: Contact WorkSafeNB to Request a Reopening

Once you have your medical reports, contact WorkSafeNB directly. Provide them with your original Claim Number and officially request that the file be reviewed for reopening. Submit your new medical evidence alongside any requests for resumed wage-loss benefits or physical therapy coverage.

Step 4: Await the Adjudicator’s Decision

A WorkSafeNB adjudicator will review your old file, the nature of the original injury, and the new medical evidence. 👨‍⚐️ They may also request that you attend an Independent Medical Examination (IME) to verify your doctor’s findings. If they agree the injury is connected, your file will be reopened. If they deny the request, you have the right to appeal the decision to the Decision Review Office (DRO) and subsequently the Workers’ Compensation Appeals Tribunal (WCAT).

How Much Does it Cost in New Brunswick?

Requesting that WorkSafeNB reopen your file is an administrative procedure that does not involve government application fees. However, securing the necessary medical and legal support may involve some costs.

  • WorkSafeNB Fees: $0 CAD. There is no charge to request a review or reopen a file.
  • Medical Reports: While standard doctor visits are covered by Medicare, specialized medical-legal reports required to prove “continuity” can cost you between $100 and $500 CAD.
  • Lawyer Fees: If WorkSafeNB refuses to reopen the file and you must hire a law firm to file an appeal, lawyers generally charge between $2,000 and $5,000 CAD for representation, or they may work on a contingency percentage of your back-pay.

How Long Does the Process Take?

Reopening a claim takes time because WorkSafeNB must thoroughly investigate to ensure the current injury isn’t due to sports, age-related degeneration, or a separate accident. ⌛ Once you submit your new medical evidence, the initial review process usually takes 3 to 6 weeks.

If WorkSafeNB requires you to see one of their own medical specialists for an independent evaluation, the timeline can easily stretch to 2 to 4 months. If the file is successfully reopened, your wage-loss benefits and treatment coverage can often be retroactively applied to the date the flare-up was medically documented.

Frequently Asked Questions (FAQ)

Is there a time limit to reopen a WorkSafeNB claim?

Generally, there is no strict statutory time limit on reopening a claim if the medical evidence clearly links the current severe deterioration to the original workplace accident, even if years have passed. However, the longer the gap, the harder it is to prove.

What if my flare-up happened while working for a new employer?

If the flare-up is clearly a recurrence of the old injury without a new specific accident, it will usually be tied to your old claim. If a new specific incident caused the pain, you will likely need to file an entirely new claim with your new employer.

Do I have to stop working to reopen my claim?

Not necessarily. You can request to reopen your file solely to get medical treatments (like physiotherapy or surgery) covered, even if you are still physically capable of working modified duties and earning your regular wages.

What if my doctor says it’s arthritis, not the old injury?

If the deterioration is due to natural age-related degeneration (like arthritis) rather than the workplace accident, WorkSafeNB will likely deny the request to reopen. The medical evidence must prove the workplace injury is the primary cause.
