Medical certificates from the psychiatrist: leave, fitness for work, and how much to say

A medical certificate is the shortest document a psychiatrist signs and the one most often read by someone who is not a clinician: a manager, a payroll officer, an HR adviser. The leave certificate is evidence that the person was unfit for work for a stated period; the fitness-for-work certificate is a statement of what they can do now and under what conditions. Neither needs the diagnosis, both need exact dates, and both are formal statements the Medical Board expects to be accurate to the word.

What these certificates are for

Two documents, two different jobs, one standard of care in writing them.

The leave certificate is evidence for the employer that the person was, or is, unfit for work for a stated period, so that personal leave can be taken and paid. Under the Fair Work Act, an employee asked for evidence must provide evidence that would satisfy a reasonable person, and a medical certificate is the accepted form. Its reader is payroll or HR; they check the name, the dates and that a registered practitioner signed it.

The fitness-for-work certificate is a statement of what the person can do now: fit, unfit, or fit with stated restrictions, for how long, with a review date. Its reader is a manager or return-to-work coordinator who has to roster around it, and who cannot act on anything vague.

Both are formal statements by a registered practitioner. The Medical Board's code of conduct expects them to be honest, accurate and not misleading, and they are held to that standard word by word: the dates, the date of consultation, the period certified, and what was actually assessed.

What the law requires, and what it does not

The Act requires evidence that would satisfy a reasonable person. It does not require the diagnosis, and an employer cannot insist on it. A certificate stating that the person was unfit for work due to a medical condition from one date to another, signed and dated by a registered practitioner, satisfies the requirement. Any more detail is the patient's confidential information, disclosed only with their agreement.

The professional conventions add the rest: the certificate states the date of consultation; a period certified before that date is possible where you are satisfied on the history and examination, and must be clearly shown as such; the period is defined, with an end date or a review date; and the certificate identifies you fully, with provider number and contact details, on letterhead.

The leave certificate: what it must contain

  1. The patient's name. As known to the employer.
  2. The date of consultation. The date you assessed the patient, stated plainly.
  3. The statement. That in your opinion the person is, or was, unfit for work due to a medical condition.
  4. The period. From a date to a date. If any of it precedes the consultation, say so and say it is certified on history and examination.
  5. Nothing about the diagnosis, unless the patient has asked for it to be included.
  6. Your identification. Name, qualifications, AHPRA registration, provider number, practice address and contact, signature, on letterhead.

A carer's leave certificate follows the same pattern, stating that the person was required to care for a family or household member who was unwell, without identifying the member's condition.

The fitness-for-work certificate: what it must contain

  1. The patient's name and the date of consultation.
  2. The capacity statement. Fit for full duties; unfit for all work until a date; or fit for work with restrictions.
  3. The restrictions, specifically. Hours per day and days per week; duties that can and cannot be performed; environmental conditions (no night shifts, no lone working, no client-facing work); anything that must be avoided. A restriction the manager cannot roster is not a restriction.
  4. The duration and the review date. How long the restrictions apply and when they will be reassessed.
  5. The anticipated course, if you can give one: an expected date for full duties, or the next step.
  6. A pointer to adjustments, where the workplace needs to change something. The detail belongs in a separate accommodation letter, not in the certificate.
  7. Your identification and signature, on letterhead.

Mental health specifics

The stigma is real and the reader is not a clinician, so the vocabulary should be functional rather than clinical. What the person can and cannot do, for how long, in what conditions. "Medical condition" is the standard wording, and it is the patient's decision, taken with knowledge of who will read the document, whether the condition is named.

A return after a mental health absence is often graduated, and a manager needs it written as a plan: hours and duties by week, the review points, and who to contact. That is a separate document, the Employer - Graduated Return to Work preset, as are the Workplace Accommodation Letter for adjustments and the Employer - Medical Clearance to Return for the employer who requires clearance before the person resumes. The certificate should point to them, not try to be them.

Where certificates fall short

  • The period has no end date, or "indefinitely", which invites an independent examination and leaves the employer unable to plan.
  • The date of consultation is missing, or a retrospective period is not shown as retrospective.
  • The diagnosis appears without the patient having chosen to disclose it.
  • "Fit with restrictions" with no restrictions stated, or restrictions no roster can implement.
  • No review date on a fitness-for-work certificate.
  • Provider details, signature or letterhead missing, so payroll queries it.
  • The certificate tries to be the return-to-work plan or the accommodation letter as well.

Two skeletons that work

The leave certificate:

Medical certificate
I certify that I consulted [Name] on [date] and that, in my opinion, [he / she / they] [is / was] unfit for work due to a medical condition from [date] to [date] inclusive. [Where applicable: the period from [date] to [date] preceding the consultation is certified on the basis of history and examination.]
[Name, qualifications, AHPRA registration number, provider number, practice, contact, signature, date]

The fitness-for-work certificate:

Certificate of fitness for work
I consulted [Name] on [date]. In my opinion [he / she / they] [is fit for full duties from [date] / is unfit for all work until [date] / is fit for work with the following restrictions from [date] to [date]]:
- Hours: [x] hours per day, [y] days per week.
- Duties: [can perform ...; should not perform ...].
- Conditions: [no night shifts / no lone working / other].
Review on [date]. [Anticipated return to full duties: [date], subject to review.] [Where workplace adjustments are recommended, these are set out in a separate letter.]
[Name, qualifications, AHPRA registration number, provider number, practice, contact, signature, date]

How PsychDispatch drafts these

The Medical Certificate - Fitness for Work and Medical Certificate - Leave / Absence presets draft each certificate from the consultation with the dates filled from the record rather than from memory, the capacity statement and restrictions in the functional vocabulary above, and nothing about the diagnosis unless you put it there. Every date is verified against the source before you sign, the certificate is rendered onto your letterhead, which is the part payroll actually checks, and it goes to the patient or, with their agreement, the employer by secure link.

FAQ

Questions about this letter.

Can the employer demand the diagnosis?

No. The Fair Work Act asks for evidence that would satisfy a reasonable person that the leave was taken for the stated reason, and a certificate stating that the person was unfit for work due to a medical condition for the period does that. The diagnosis is the patient's confidential information. It goes on a certificate only if the patient wants it there, usually because they are seeking adjustments and have decided disclosure helps them.

Can I certify a period before the consultation?

You can certify that in your opinion the person was unfit for a period before you saw them, if you are satisfied of it on the history and examination, provided the certificate states the date of the consultation and makes clear that the earlier dates are certified on that basis. What you cannot do is state or imply that the consultation happened on a date it did not.

Is a certificate from a telehealth consultation valid?

Yes, provided a proper assessment took place. The certificate is a statement of your opinion after assessing the patient; the mode of consultation does not change what it must contain or the standard it is held to.

How long a period should a certificate cover?

As long as is clinically justified and no longer. Long or open-ended periods invite challenge and independent examination, and they leave the employer unable to plan. Where the absence will be extended, a certificate for a defined period with a review date, renewed if needed, serves the patient better than "unfit indefinitely".

Is a fitness-for-work certificate the same as a WorkCover certificate of capacity?

No. The certificate of capacity is a scheme form for a compensable injury, read by an insurer against the scheme's rules, and it has its own preset. The fitness-for-work certificate described here is for the employer directly, outside a claim, and follows the Fair Work and Medical Board framework rather than a scheme's.

Should the certificate say "psychiatric" or name my specialty?

Your letterhead will identify you as a psychiatrist, which the patient should know before you write it. Beyond that, "medical condition" is the standard wording and discloses nothing. Some patients ask for the condition to be named so that adjustments can be requested; that is their decision, made with the knowledge of who will read it.
