When billing to Medicare on a CMS 1500 claim form for the ASC, who's NPI should be in box 24J? So if Dr. X performs the surgery/procedure, but the claim is for the ASC, do you put Dr. X's NPI in 24J, or the ASC's? I know the ASC's NPI is in box 33, as they are the billing provider. Everything that I have looked at just stats the rendering provider in 24J....but who is the rendering provider in this case?
