Yes. If your accepted condition/s worsen, or if you have other conditions accepted which also cause a degree of permanent impairment, you will be able to lodge a claim for additional DVA Permanent Impairment (PI) compensation.
Additional PI compensation can be paid where your impairment has increased by at least 5 impairment points.
However, this compensation can only be increased up to the maximum rate. If you are currently receiving the maximum rate these payments cannot be increased.
