Falsify a medic (6)
I believe the answer is:
doctor
This clue is a double definition.
'falsify' is the first definition.
(I've seen this in another clue)
'a medic' is the second definition.
(I've seen this before)
(Other definitions for doctor that I've seen before include "Foster, Who, Jekyll or Livingstone" , "Tamper with - falsify - one of the 14 films" , "Onshore breeze" , "Medical worker or holder of highest university degree" , "19 [WHO] , say" .)
