Can my physio or psychologist issue a NSW workers compensation certificate of capacity?

Who completes the first certificate?

For a new NSW workers compensation claim, the first certificate of capacity is still a medical certificate step. In practice, that usually means seeing your nominated treating doctor or another medical practitioner who can assess the injury, capacity for work, treatment needs, and whether the injury is connected to work.

This matters because the first certificate often becomes the foundation for provisional liability, weekly payments, treatment approval, and early return-to-work planning. If the first certificate is missing, vague, or completed by the wrong provider, the insurer may ask for more information before payments or treatment are progressed.

When can a physio or psychologist certificate help?

After the first certificate, SIRA public guidance says SIRA-approved treating physiotherapists and psychologists can issue second and subsequent certificates for injuries within their areas of expertise using the designated form. That can be useful when your ongoing restriction is mainly physical and your treating physiotherapist is closely measuring function, or when your ongoing restriction is psychological and your treating psychologist is closely monitoring symptoms, triggers, hours, concentration, or interpersonal exposure.

The certificate still needs to be practical. A useful certificate does not only say “unfit” or “light duties”. It should describe what you can and cannot safely do in work terms: hours, lifting, bending, sitting, standing, walking, driving, travel, breaks, medication effects, concentration, interaction with particular people, conflict exposure, or staged upgrading if those matters are relevant.

Limits and risks workers should not miss

The main limit is scope. A physiotherapist certificate is strongest when the disputed capacity issue is within physiotherapy expertise. A psychologist certificate is strongest when the capacity issue is within psychological expertise. If the claim involves medication, surgery, multiple body parts, psychiatric diagnosis, neurological symptoms, or causation questions, the insurer may still need doctor or specialist evidence.

Another risk is duration. SIRA source material identifies that a certificate of capacity cannot be issued for more than 28 days without specific reasons for the extended period under section 44B(4)(a) of the Workers Compensation Act 1987. If a certificate covers a longer period, make sure the reasons are recorded clearly rather than assuming the insurer will accept it.

Finally, keep the certificate aligned with the rest of the file. If your physiotherapist says you can lift 10 kilograms, your GP says no lifting, and the recovery at work plan asks for stock handling, the insurer may treat the inconsistency as a work capacity issue. Fixing that mismatch early is usually safer than arguing after payments are reduced.

Worker checklist before relying on an allied health certificate

1. Check the certificate stage. Is this the first certificate, or a second or later certificate?
2. Confirm SIRA approval. Do not assume a provider can certify just because they treat workers compensation patients.
3. Check scope of practice. The certified restrictions should fit the provider’s professional area and the injury being treated.
4. Use the designated form. Keep a copy of the completed certificate and send it to the insurer promptly.
5. Avoid certificate gaps. Weekly payments and return-to-work plans often depend on current capacity evidence.
6. Ask for practical restrictions. Hours, tasks, travel, breaks, lifting, sitting, standing, concentration, and psychological triggers are usually more useful than broad labels.
7. Align the providers. If your GP, specialist, physiotherapist, psychologist, and rehab provider are saying different things, ask them to clarify the exact mismatch.

What if the insurer or employer pushes back?

Ask for the reason in writing. There is a big difference between a form problem, a date gap, a provider-approval issue, a scope-of-practice concern, and a real dispute about your capacity. Each one needs a different fix.

If the problem is technical, such as the wrong form or a missing date, correct it quickly. If the problem is substantive, such as the insurer saying you can return to duties the certificate does not support, collect the certificate, actual duty description, recovery at work plan, employer emails, and treating reports together. Then check whether the issue is a work capacity decision, a recovery at work plan mismatch, or a broader section 78 dispute.

If the insurer has already reduced or stopped weekly payments, do not assume that sending a clearer certificate is enough. Read the decision letter, identify the review or dispute pathway, and get advice quickly before a response window is missed.

Source basis and accuracy note

This article is based on current SIRA public source checking for certificates of capacity for workplace injuries, the SIRA certificate of capacity/certificate of fitness form for treating physiotherapists or psychologists, SIRA allied health practitioner guidance, SIRA employer guidance, and section 44B(4)(a) of the Workers Compensation Act 1987 as identified in SIRA public material.
