Doctor got billed crossing river here? (10)

'here?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'doctor got billed crossing river' is the wordplay.
'doctor' indicates anagramming the letters.
'crossing' indicates putting letters inside.
'river' becomes 'r'.
'got'+'billed'='gotbilled'
'gotbilled' with letters rearranged gives 'tollbidge'.
'tollbidge' enclosing 'r' is 'TOLLBRIDGE'.
