6 Kind of injury, disease or death to which this Statement of Principles relates
Meaning of temporomandibular disorder
(2) For the purposes of this Statement of Principles, temporomandibular disorder:
(a) means a heterogeneous group of conditions affecting the anatomical and functional characteristics of the temporomandibular joint, masticatory muscles and associated structures of the masticatory system, with:
(i) clinically significant pain localised in the temple, front of ear or jaw, that is modified with jaw movement, and which is experienced on more days than not within a continuous six month period; and
(ii) clinically significant distress or substantial impairment of social, occupational, educational or other important areas of functioning due to pain, limitation, deviation or other abnormality of jaw motion; and
(iii) clinical signs or imaging evidence of myalgia, arthralgia, or another pathological process affecting the temporomandibular joint, muscles of mastication and/or associated structures; and
(b) excludes:
(i) orofacial pain of dental origin;
(ii) headache or pain better accounted for by another pain or headache disorder; and
(iii) congenital or developmental orofacial disorders.
Note 1: Symptoms of temporomandibular disorder include orofacial pain, muscle or joint tenderness, pain referred to the angle of the mandible and muscles of the neck, deviated mouth opening, limitation of range of mandibular movements, headache produced or exacerbated by jaw movements, abnormal joint sounds and otolaryngological symptoms.
Signs of temporomandibular disorder include modification of pain by passive movements through the range of motion of the jaw or provocative manoeuvres applied to temporomandibular structures.
Note 2: masticatory muscles and associated structures of the masticatory system is defined in the Schedule 1 – Dictionary.
(3) While temporomandibular disorder attracts ICD‑10‑AM code M26.60, in applying this Statement of Principles the meaning of temporomandibular disorder is that given in subsection (2).
(4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from temporomandibular disorder
(5) For the purposes of this Statement of Principles, temporomandibular disorder, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's temporomandibular disorder.
Note: terminal event is defined in the Schedule 1 – Dictionary.
7 Basis for determining the factors
