1. Name This is the Statement of Principles concerning polymyalgia rheumatica (Balance of Probabilities) (No. 6 of 2025). 1. Commencement This instrument commences on 28 January 2025. 1. Authority This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986. 1. Repeal The Statement of Principles concerning polymyalgia rheumatica (Balance of Probabilities) (No. 20 of 2016) (Federal Register of Legislation No. F2016L00259) made under subsection 196B(3) of the VEA is repealed. 1. Application This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies. 1. Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 1. Kind of injury, disease or death to which this Statement of Principles relates 1. This Statement of Principles is about polymyalgia rheumatica and death from polymyalgia rheumatica. Meaning of polymyalgia rheumatica 1. For the purposes of this Statement of Principles, polymyalgia rheumatica: 1. means an inflammatory rheumatic disorder with the following characteristics: 1. bilateral aching and stiffness involving the shoulder or proximal regions of the arms; or the hip or proximal regions of the thighs; or the neck or lower back; 2. elevated acute phase reactants (erythrocyte sedimentation rate and/or C reactive protein) or systemic symptoms such as malaise, fatigue and a low-grade fever; and 3. occurring in the absence of other diseases capable of causing the musculoskeletal system symptoms; and 2. excludes polymyalgia rheumatica coexistent with giant cell arteritis. Note: In patients with polymyalgia rheumatica who can take corticosteroids, there is a rapid response to corticosteroid therapy. 1. While polymyalgia rheumatica attracts ICD‑10‑AM code M35.3, in applying this Statement of Principles the meaning of polymyalgia rheumatica is that given in subsection (2). 2. 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 polymyalgia rheumatica 1. For the purposes of this Statement of Principles, polymyalgia rheumatica, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's polymyalgia rheumatica. Note: terminal event is defined in the Schedule 1 – Dictionary. 1. Basis for determining the factors On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that polymyalgia rheumatica and death from polymyalgia rheumatica can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary. 1. Factors that must exist At least one of the following factors must exist before it can be said that, on the balance of probabilities, polymyalgia rheumatica or death from polymyalgia rheumatica is connected with the circumstances of a person's relevant service: 1. being treated with immune checkpoint inhibitors within the 1 year before clinical onset or clinical worsening; Note: Examples of immune checkpoint inhibitors include atezolizumab, avelumab, cemiplimab, durvalumab, ipilimumab, nivolumab, and pembrolizumab. 1. inability to obtain appropriate clinical management for polymyalgia rheumatica before clinical worsening. 1. Relationship to service 1. The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person. 2. The clinical worsening aspects of factors set out in section 9 apply only to material contribution to, or aggravation of, polymyalgia rheumatica where the person's polymyalgia rheumatica was suffered or contracted before or during (but did not arise out of) the person's relevant service. 2. Factors referring to an injury or disease covered by another Statement of Principles In this Statement of Principles: 1. if a factor referred to in section 9 applies in relation to a person; and 2. that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA; then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
