Where one sees patient official can tidy up (10,4)
I believe the answer is:
consulting room
'where one sees patient' is the definition.
(where a doctor might see a patient)
'official can tidy up' is the wordplay.
'official' becomes 'consul' (consul is a kind of official).
'can' becomes 'tin' (both are metal containers).
'tidy up' becomes 'groom' (groom can mean to tidy up or clean).
'consul'+'tin'+'groom'='CONSULTING ROOM'
(Other definitions for consulting room that I've seen before include "GP's place of work" , "Doctor's office" .)
