Other jobs related to clinical private

Hi, I have some good clinical hours and a boss I like in a private practice. As is often the case, the hours/pay isn’t enough at this point. I’m trying to think about steady day gigs and a new thought (I’m working a lot of different angles already) is something related to private practice like working in aligning clients insurance with practices or managing practices. Does anyone have a side or main gig in private practice that pays well and allows them to see clients in private practice? Private is ultimately where I’d like to be…I’d just like to see if there’s a way to be involved in that area while I’m building my skills and practice. Any keywords to be searching for? Thanks!
