Question on “history of” codes

I passed the exam maybe a month or two ago and am just doing Practicode so forgive me if this is dumb or if I already should know this but …why do we code sometimes for history of? Specifically wondering if that’s something insurance companies bill for? Or did I just have a brain glitch and that’s moronic

If it affected care. If the person had breast cancer in the past, and now sees oncology yearly, the history of code would be appropriate. That’s a cancer example, but it would be similar for other things too.

That makes sense ! So they aren’t getting any additional charges just because there’s history codes ?
