Hello. So I have a potential client who wouldn't need me until September which is when they go live with EMR. They said I would be using their system and all they would need me to do is review the billing, add any modifiers if needed, send it to the clearinghouse, and then follow up on unpaid or rejected claims. they would also have patients call me will billing questions. I do percent billing with my other clients but I don't think that would work for this. I'm pretty stumped as to how to charge for it. Any suggestions?
