Having a Tier 5 Visa are you covered by the NHS?

This may sound silly, but I am going over seas for the first time this summer. I am obtaining a tier 5, religious worker Visa, and I was told to ask whether I would be covered by the NHS? I have no idea about any of this stuff, thanks for being understanding!

Generally, if your visa is for longer than 6 months you are covered, if it is for 6 months or less then you are not.
