Pass taken out for health resorts (4)
I believe the answer is:
spas
'health resorts' is the definition.
(I've seen this before)
'pass taken out' is the wordplay.
'taken out' is an anagram indicator.
'pass' with letters rearranged gives 'SPAS'.
'for' acts as a link.
(Other definitions for spas that I've seen before include "Health resorts near springs" , "Bath and suchlike" , "Mineral springs" .)
