Do we "do follow up" or we just "follow up"?

Do we "do follow up" or we just "follow up"?

For example "John's work is to call the insurance company to follow up on the denied claims" or "John's work is to call the insurance company to do the follow up on the denied claims."

Both are possible. In the first, "follow up" is a verb. In the second "follow-up" (note the hyphen) is a noun. I'd start with "John's job ...", not "John's work".

I would use denied claims rather than the denied claims.
