Yes. Follow-up is a hyphenated word. Sometimes. Here's how to tell when it is and when it is not hyphenated:
If you can use the word the directly in front of the words follow up, they need a hyphen. If not, no hyphen is needed.
Why? Well, since we never use "the" before verbs, if you cannot insert "the" before "follow up", you know the phrase is a verb, which means you do not use a hyphen. When "follow up" is a noun or an adjective, it does need a hyphen.

My educated guess is that it is used without a hyphen when used as a verb, and with a hyphen when used as an adjective. Dr. Smith is on call. He is the on-call physician. Similar to follow up: Dr. Smith will follow up with the patient when she has her follow-up visit.

"Fired up" is one of those phrases that is hyphenated when it is used as a modifier preceding whatever it is modifying, but not hyphenated when it is used as a predicate adjective. For example, if you say "Everyone was fired up about the new project", "fired up" is a predicate adjective and not hyphenated. However, if you refer to someone's "fired-up speech", "fired-up" is a modifier that precedes "speech" and is therefore hyphenated. Using "fired up" as a predicate adjective is more common.
