5 conditions in the Repatriation Medical Authority's Statements of Principles list psoriatic arthritis as a factor. If DVA has accepted your psoriatic arthritis, 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 psoriatic arthritis, and another condition's SoP lists psoriatic arthritis 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 (2): “having one of the following autoimmune diseases for at least the 1 year before clinical onset or clinical worsening; (a) ankylosing spondylitis; (b) dermatomyositis; (c) psoriatic arthritis; (d) rheumatoid arthritis; (e) systemic lupus erythematosus; or (f) systemic sclerosis” [onset and worsening]
This factor appears in the Reasonable Hypothesis instrument only, which applies to operational service.
If any of these is also on your file, it reaches some of the same conditions psoriatic arthritis 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.
Psoriatic arthritis, for the purposes of the Statement of Principles, for the purposes of this Statement of Principles, psoriatic arthritis means a seronegative chronic inflammatory arthritis, occurring in association with skin or nail psoriasis.
Aggravation-only factors. In this instrument, subsections 9(4) to 9(5) apply only to material contribution to, or aggravation of, psoriatic arthritis where it was already present before or during service. If service caused psoriatic arthritis outright, those factors are not available to you.
RH No. 15 of 2021 · BoP No. 16 of 2021 · 5 factors
The Statement of Principles for psoriatic arthritis names 1 other condition among its own factors. If any of these is already accepted on your file, it may be the factor that carries a psoriatic arthritis claim — quoted here from the instrument.
Reasonable Hypothesis — factor (1): “having psoriasis at the time of the clinical onset of psoriatic arthritis” [clinical onset]
Balance of Probabilities — factor (1): “having psoriasis at the time of the clinical onset of psoriatic arthritis” [clinical onset]
