Wrong treatment for misers (6)

I believe the answer is:

remiss

'wrong' is the definition.
(I've seen this before)

'treatment for misers' is the wordplay.
'treatment for' indicates an anagram (I've seen this in other clues).
'misers' is an anagram of 'REMISS'.

(Other definitions for remiss that I've seen before include "Culpable" , "delinquent" , "Negligent in performing duties" , "Not taking care" , "Careless and inattentive" .)

I've seen this clue in the Evening Standard.
