'Sequelae' are medical conditions which, although they are medical conditions clearly distinguishable from the original injury, have arisen as a consequence of the original injury (eg the onset of osteoarthritis in a knee joint arising from an earlier traumatic injury to that knee or the onset of a psychiatric illness in response to pain and disability of that knee, are both medical sequelae).
A separate determination for each sequela is required.
There are 44 sequelae for which a streamlining policy is in place. For more information on these conditions and the circumstances under which decisions relating to them are to be streamlined, see 3.4.5.2 Sequelae streamlining policy.
