7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about microscopic polyangiitis and death from microscopic polyangiitis.
Meaning of microscopic polyangiitis
(2)          For the purposes of this Statement of Principles, microscopic polyangiitis:
(a)          means a necrotising non-granulomatous vasculitis with few or no immune deposits predominantly affecting small vessels (capillaries, venules or arterioles); and
(b)          excludes polyarteritis nodosa, granulomatosis with polyangiitis (Wegener granulomatosis) and eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome).
Note:  Microscopic polyangiitis commonly manifests in the kidney as rapidly progressive crescentic glomerulonephritis, or in the lungs as pulmonary capillaritis.  Antineutrophil cytoplasmic antibodies (ANCA) are usually present.
(3)          While microscopic polyangiitis attracts ICD‑10‑AM code M31.7, in applying this Statement of Principles the meaning of microscopic polyangiitis 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 microscopic polyangiitis
(5)          For the purposes of this Statement of Principles, microscopic polyangiitis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's microscopic polyangiitis.
Note: terminal event is defined in the Schedule 1 – Dictionary.
