1 condition in the Repatriation Medical Authority's Statements of Principles list microscopic polyangiitis as a factor. If DVA has accepted your microscopic polyangiitis, each of these has a documented pathway to a further claim.
Some Statement of Principles factors are not about service at all — they name another condition. Where DVA has already accepted your microscopic polyangiitis, and another condition's SoP lists microscopic polyangiitis as a factor, that part of the next claim is already established on your file. How a secondary claim works, in full →
Quoted from the instrument. A pathway existing is not the same as a claim succeeding — each factor carries thresholds your record has to satisfy.

Reasonable Hypothesis — factor (15): “having one of the following vasculitides: (a) Behcet's disease; (b) eosinophilic granulomatosis with polyangiitis (Churg Straus syndrome); (c) giant cell (temporal) arteritis; (d) granulomatosis with polyangiitis (Wegener's granulomatosis); (e) microscopic polyangiitis; (f) polyarteritis nodosa; or (g) Takayasu's arteritis; at the time of the clinical onset or clinical worsening of pericarditis” [onset and worsening]
Balance of Probabilities — factor (15): “having one of the following vasculitides: (a) Behcet's disease; (b) eosinophilic granulomatosis with polyangiitis (Churg Straus syndrome); (c) giant cell (temporal) arteritis; (d) granulomatosis with polyangiitis (Wegener's granulomatosis); (e) microscopic polyangiitis; (f) polyarteritis nodosa; or (g) Takayasu's arteritis; at the time of the clinical onset or clinical worsening of pericarditis” [onset and worsening]
If any of these is also on your file, it reaches some of the same conditions microscopic polyangiitis does.
A claim is tested against the definition first. If the diagnosis on your file does not meet this wording, the factors below never get reached — so it is worth checking that what your doctor wrote matches what the instrument requires.
Microscopic polyangiitis, for the purposes of the Statement of Principles, 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 the exclusion. This instrument expressly excludes Polyarteritis nodosa, granulomatosis with polyangiitis (Wegener granulomatosis) and eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome). A diagnosis of that is not a diagnosis of microscopic polyangiitis, and a claim framed the wrong way fails on the definition before any factor is considered.
Aggravation-only factors. In this instrument, subsections 9(4) to 9(7) apply only to material contribution to, or aggravation of, microscopic polyangiitis where it was already present before or during service. If service caused microscopic polyangiitis outright, those factors are not available to you.
