Declines home visits (5,2)
I believe the answer is:
drops in
'visits' is the definition.
(dropping in is a kind of visiting)
'declines home' is the wordplay.
'declines' becomes 'drops' (dropping is a kind of declining**).
'home' becomes 'in' ('he's home' can mean 'he's in').
'drops'+'in'='DROPS IN'
(Other definitions for drops in that I've seen before include "Comes to see" , "eye thus getting less inflamed?" , "Calls casually" , "Casually visits" .)
