MOTOR ACCIDENTS - Motor Accident Injuries Act 2017; review of Medical Assessment Certificate (MAC); threshold injury and treatment disputes; Medical Assessor certified adjustment disorder with mixed anxiety and depressed mood caused by accident was a threshold injury and referral to a psychiatrist relates to psychological injury caused by the accident and is reasonable and necessary in the circumstances; - post-traumatic stress disorder (PTSD) caused by the accident was not a threshold injury; MAC revoked; new certificate issued; certificates relating to treatment confirmed.
(a) whether the request for referral for a consultation with Dr Kuljic, psychiatrist, relates to the injury caused by the accident on 14 February 2021, and
(b) whether the request for referral for a consultation with Dr Kuljic, psychiatrist, is reasonable and necessary in the circumstances.
(a) a psychological injury caused by the accident is a threshold injury, and
(b) referral to Dr Kuljic relates to the psychological injury caused by the accident and is reasonable and necessary in the circumstances.
5.3 The assessment will determine whether the injury related to the claim is a soft tissue injury or a threshold psychological or psychiatric injury caused by the motor accident.
5.5 A diagnosis for the purpose of a threshold injury decision must be based on a clinical assessment by a medical practitioner or other suitably qualified person independent from the insurer.
5.6 The assessment of whether an injury caused by the accident is a threshold injury for the purposes of the Act should be based on the evidence available and include all relevant findings derived from:
(a) a comprehensive accurate history, including pre-accident history and pre-existing conditions
(b) a review of all relevant records available at the assessment
(c) a comprehensive description of the injured person's current symptoms
(d) a careful and thorough physical and/or psychological examination
(e) diagnostic tests available at the assessment. Imaging findings that are used to support the assessment should correspond with symptoms and findings on examination."
"Threshold psychological or psychiatric injury assessment
5.10 In assessing whether an injury is a threshold psychological or psychiatric injury, an assessment of whether a psychiatric illness is present is essential.
5.11 The assessment of whether a psychiatric illness is present must be made using the Diagnostic & Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), published by the American Psychiatric Association.
5.12 Where the symptoms associated with the injured person's psychological or psychiatric injury do not meet the assessment criteria for a recognised psychiatric illness, with the exception of acute stress disorder and adjustment disorder, the injury will be considered a threshold injury."
6.5 An assessment of the degree of permanent impairment is a medical assessment matter under clause 2(a) of Schedule 2 of the Act. The assessment must determine the degree of permanent impairment of the injured person as a result of the injury caused by the motor accident. A determination as to whether the injured person's impairment is related to the accident in question is therefore implied in all such assessments. Medical assessors must be aware of the relevant provisions of the AMA4 Guides, as well as the common law principles that would be applied by a court (or the Personal Injury Commission) in considering such issues.
6.6 Causation is defined in the Glossary at page 316 of the AMA4 Guides as follows:
'Causation means that a physical, chemical or biologic factor contributed to the occurrence of a medical condition. To decide that a factor alleged to have caused or contributed to the occurrence or worsening of a medical condition has, in fact, done so, it is necessary to verify both of the following:
This, therefore, involves a medical decision and a non-medical informed judgement.
6.7 There is no simple common test of causation that is applicable to all cases, but the accepted approach involves determining whether the injury (and the associated impairment) was caused or materially contributed to by the motor accident. The motor accident does not have to be a sole cause as long as it is a contributing cause, which is more than negligible. Considering the question 'Would this injury (or impairment) have occurred if not for the accident?' may be useful in some cases, although this is not a definitive test and may be inapplicable in circumstances where there are multiple contributing causes."
"The question of causation of injuries was not dealt with in Part 5 of the Guidelines but causation was addressed in Part 6, which related to assessment of permanent impairment. There is no reason to think that different principles were intended to be applied when a medical assessment was being made in relation to causation of minor injuries."
"...driver of stationary car, was rear ended at low speed
"I was stopped at traffic lights when a car suddenly rear ended me. An ambulance came to take me & my sister to hospital. The force of the impact from behind caused us to hit the car in front."
Dr Manohar's reports. On 9 August 2021 Dr Manohar recorded that the claimant was unable to sleep because of pain and was "very traumatised". 5. A report from Dr Oreb dated 3 July 2021 records that the claimant presented for the first time on 1 March 2021 with a history of being involved in a motor accident on 14 February 2021. She reported headaches, neck, back, chest, and bilateral knee pain. The doctor diagnosed "post traumatic mechanical derangement" of the cervical spine, thoracic lumbar spine, right knee and right hip. The Panel infers that reference to "P.T.M.D" in the diagnosis section of certificates completed by the doctor is a reference to "post traumatic mechanical derangement".

(b) 22 April 2021 - stressed with pain in neck and back;
