Get back concerning insurance (7)
I believe the answer is:
recover
'get back' is the definition.
(I've seen this before)
'concerning insurance' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'insurance' becomes 'cover' (I've seen this before).
're'+'cover'='RECOVER'
(Other definitions for recover that I've seen before include "Recuperate" , "comeback" , "Find" , "Rally, get better" , "Bring back" .)
