I am very new to billing IM and am having issues getting MC to pay for Obs codes. I am billing 99220 and 99217 no mod, with a place of service of the Hospital the patient is at. They are being denied for Invalid place of service. From what I have read I need to change the location to outpatient 22? Is that right? Unfortunately our software doesn't allow me to go in and change it so I will need to contact them if thats the case. Do I need modifiers?
Thanks!
Thanks!
