Get better regarding insurance (7)
I believe the answer is:
recover
'get better' is the definition.
('recover' can be a synonym of 'get better')
'regarding insurance' is the wordplay.
'regarding' becomes 're'.
'insurance' becomes 'cover' (I've seen this before).
're'+'cover'='RECOVER'
(Other definitions for recover that I've seen before include "comeback" , "Bring back" , "Get better; retrieve" , "Get well again" , "Rally, get better" .)
