(Fatwa: 609/507/D=1434)
When it is necessary to avail health insurance as per the rule as well it is done by the company and you have nothing to do then there is no harm in taking insurance as per the Shariah. As far as the matter of getting benefit from it is concerned, if you have no interfere in it rather the company itself pays the premium or it deducts from your salary compulsorily without seeking your consent then you may avail the benefit mentioned therein the question.
Allah knows Best!
