A medical or clinical reason that argues against a particular treatment or procedure, the opposite of an indication.
From 'counter-' (opposite) and 'vindication,' from Latin 'vindicare' (to justify, claim). Medical terminology adapted this to mean reasons that contradict the justification for a treatment.
