2 conditions in the Repatriation Medical Authority's Statements of Principles list ascariasis as a factor. If DVA has accepted your ascariasis, 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 ascariasis, and another condition's SoP lists ascariasis 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.

If any of these is also on your file, it reaches some of the same conditions ascariasis 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.
Ascariasis, for the purposes of the Statement of Principles, for the purposes of this Statement of Principles, ascariasis means an infection with the intestinal roundworm Ascaris lumbricoides or Ascaris suum. (3) While ascariasis attracts ICD-10-AM code B77, in applying this Statement of Principles the meaning of ascariasis 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), Ninth Edition, effective date of 1 July 2015, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-020-5.
Aggravation-only factors. In this instrument, subsections 9(4) apply only to material contribution to, or aggravation of, ascariasis where it was already present before or during service. If service caused ascariasis outright, those factors are not available to you.
