Code solved with right furnishings (5)
I believe the answer is:
decor
'furnishings' is the definition.
(decoration of a room)
'code solved with right' is the wordplay.
'solved with' is an anagram indicator (the anagram must be solved).
'right' becomes 'r' (common abbreviation).
'code' mixed up with 'r' can make 'DECOR'.
(Other definitions for decor that I've seen before include "Room colour scheme, furnishings, etc" , "Internal ornamentation" , "Colour-scheme etc of a room" , "Interior design; stage scenery" , "stage background" .)
