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

What to do before the current certificate expires

If your certificate is close to expiring, act before there is a gap. Book the earliest available appointment with your nominated treating doctor or another medical practitioner, and ask your treating physiotherapist or psychologist whether they are SIRA-approved to issue a second or later certificate for the specific injury they are treating.

Send the insurer a short written update before the expiry date. Attach any new certificate, confirm who completed it, explain whether it is a first or later certificate, and keep proof that you sent it. If you cannot get a certificate in time, keep appointment confirmations and ask the insurer what temporary information it needs while you obtain updated capacity evidence.

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.

Why the certificate matters for payments and duties

In a NSW workers compensation claim, the certificate of capacity is one of the main documents connecting medical restrictions to practical workplace decisions. The insurer will usually compare the certificate with the worker's pre-injury duties, the employer's proposed suitable duties, treatment reports, surveillance or factual material if any exists, and the recovery at work plan. A later allied health certificate is more persuasive when it explains the restriction in work terms rather than only naming the diagnosis.

For weekly payments, the certificate can affect whether the worker is treated as having no current work capacity, some current work capacity, or capacity for particular hours or tasks. For return to work, it can affect whether a proposed upgrade is safe, whether duties need to be modified, and whether a disagreement should be handled as a plan mismatch, a medical evidence issue, or a formal work capacity decision. If the certificate and the proposed duties do not line up, ask for the exact duty description and respond with the specific restriction that prevents or limits the task.

The practical process is to keep the certificate current, send it before expiry where possible, keep proof of delivery, and ask for any objection in writing. If the insurer accepts the certificate, check that the recovery at work plan and payment calculations are updated consistently. If the insurer does not accept it, the next step is usually targeted evidence: a corrected certificate, a GP or specialist report, a treating physiotherapist or psychologist report explaining functional restrictions, or advice about the review pathway.

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.

Evidence to send with the certificate

When a later certificate comes from a physiotherapist or psychologist, it is often safer to send a short cover note that explains why the provider is the right person to comment on that capacity issue. Keep it practical: the certificate date range, the body part or psychological condition being treated, the duties affected, whether the provider is SIRA-approved for this certificate, and whether the restrictions match the current recovery at work plan.

Useful supporting material can include treatment notes or reports, a current GP or specialist referral if there is one, the proposed duties, roster or hours, employer emails about suitable work, and any symptom diary showing what happens after attempted duties. For psychological injuries, record the specific workplace triggers and interpersonal restrictions rather than only saying “stress”. For physical injuries, record task tolerances such as lifting, bending, standing, driving, or repetitive use.

Short cover note you can adapt

A simple cover note can reduce confusion: “I attach my current certificate of capacity dated [date]. This is a second or later certificate, not the first certificate for the claim. It was completed by my treating [physiotherapist/psychologist], who is SIRA-approved for this type of certificate. The restrictions relate to [injury/condition] and should be read with the proposed duties dated [date]. Please tell me in writing if the insurer says there is a form, approval, scope, date, or capacity issue.”

Keep the wording factual. Do not overstate what the provider can certify. If the insurer raises a problem, the written reason helps you work out whether the next step is a corrected form, extra GP or specialist evidence, a work capacity review, or legal advice.

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. Direct live SIRA page fetches were blocked by source-access during verification, so this guide uses conservative wording and does not claim that every physiotherapist or psychologist can issue every certificate.
