About This Service
Recent reforms in NSW now allow appropriately trained GPs to provide a wider range of ADHD care, including, for a select group of GPs who have completed advanced Tier 2 training, the ability to assess, diagnose, and initiate ADHD medication.
Dr Katrina Mikhail is one of a small number of GPs in NSW to complete this training, making Shire Family Medical one of the few GP practices in the Sutherland Shire able to offer a complete pathway from initial assessment through to ongoing management, without requiring a referral to a psychiatrist or paediatrician.

New Assessment Appointments
The initial ADHD assessment is structured across two parts in the same visit, totalling 1 hour and 15 minutes.
Nurse Appointment
You will first meet with our practice nurse, who will review and total your completed questionnaires, take baseline measurements including blood pressure, heart rate, height, weight, and BMI, and perform an on-site ECG.
GP Assessment with Dr Mikhail
A detailed clinical assessment with Dr Katrina Mikhail, covering your history, symptoms across settings, childhood presentation, and current functioning. Dr Mikhail will review your completed questionnaires, discuss findings, and advise on diagnosis and next steps, including whether medication is appropriate.
Outcome & Next Steps
Dr Mikhail will discuss whether ADHD is diagnosed, whether medication is appropriate and which options are available, any further information or assessment required, and your ongoing management plan.
Please note: Medication is not always indicated or appropriate. A thorough assessment is completed first. In some cases, further information or a follow-up appointment may be needed before a diagnosis or prescription can be finalised.
Before Your Assessment
Download, print and complete the relevant questionnaires and bring them with you to your appointment. If questionnaires are not completed prior to your visit, your assessment may not be able to proceed.

Preparing for Your Appointment
- Completed questionnaires — essential, appointment may not proceed without these
- A written account of how ADHD has impacted you throughout your life. Please prepare this in advance and bring it to your appointment
- Current medication list (if applicable)
- Any previous psychological, psychiatric, or allied health assessments
- Previous school reports or written evidence of symptoms in childhood (adults and children)
- Hearing and vision test results (children)
- School-aged children: if possible, a letter from your child's teacher outlining their observations and concerns about ADHD behaviour in the classroom
- Adults: written collateral history from a family member who can describe their observations of your behaviour and symptoms
- Any recent blood tests or investigations
- Medicare card
- Any other relevant medical or psychological information
School reports matter for adult assessments too. ADHD requires evidence of symptoms across settings and from childhood. Old school reports, if you have them, meaningfully support the assessment, even for adult patients.

Common Questions
Frequently Asked Questions
No. You do not need a referral from a GP or any other doctor to book an ADHD assessment with Dr Katrina Mikhail. You can call our reception team directly on 02 9545 1777 to arrange an appointment.
Recent NSW Health reforms created two levels of GP involvement in ADHD care. Tier 1 (continuation prescribers) can provide ongoing prescriptions for patients who already have a diagnosis. Tier 2 (endorsed prescribers) have completed additional, advanced training that allows them to assess, diagnose, and initiate ADHD medication. Dr Katrina Mikhail is a Tier 2 Endorsed Prescriber — one of a select cohort of GPs in NSW to complete this training.
No. Assessment appointments must be booked by calling the practice on 02 9545 1777. Our reception team will confirm the service is suitable for you and take a non-refundable deposit. Ensure you complete the relevant questionnaires before your appointment.
For children and adolescents, the SNAP-IV and Vanderbilt scales (home and school versions) are essential. For adults, a minimum of one questionnaire from the ASRS, WURS, or DIVA-5 is required. If questionnaires are not completed before your appointment, the assessment may not be able to proceed.
Not necessarily. A thorough assessment is completed first, and a diagnosis and medication are only provided where clinically appropriate. In some cases, further information, additional questionnaires, or a follow-up appointment may be needed before a final decision can be made. Dr Mikhail’s priority is safe and accurate assessment, not a predetermined outcome.
The total fee for the initial ADHD assessment is $690. A non-refundable deposit of $130 is required at the time of booking and this forms part of the total fee. The remaining $560 is payable on the day of your appointment. An estimated Medicare rebate of approximately $128 may apply to eligible patients, leaving an estimated out-of-pocket cost of approximately $562. Medicare rebates are subject to eligibility and may vary. Please confirm current rebate information with our reception team when booking. This service is not bulk billed.
Yes. The ADHD assessment service is available for patients aged 6 and over, including children and adolescents. A parent or guardian must be present throughout the appointment. For children, both the SNAP-IV and Vanderbilt questionnaires are required — including teacher-completed versions — so please allow sufficient time to collect these before your appointment.
It depends on whether you are currently established and stable on ADHD medication. If you have a diagnosis but are not yet on medication, or are not stable on your current medication, please book an ADHD assessment appointment with Dr Mikhail — she can review your situation, assess whether medication is appropriate, and initiate treatment where indicated. If you already have a confirmed diagnosis and are stable on an existing medication, you may be eligible for our continuing prescriptions service instead. You will need a current correspondence letter from your psychiatrist or paediatrician and must be registered for MyMedicare at our practice. See our ADHD Continuing Prescriptions page for full details, or call us on 02 9545 1777 if you are unsure which pathway is right for you.
