We are having a lot of pt’s that are in the hospital less than one over night or maybe they stayed 2 nights but insurance is denying in patient stay but will approve obs or out patient status. Our clinic docs see pt’s in our hospital and I do the billing for the provider’s charges only. I usually get the notice of status change after DC and sometimes after I’ve billed the hospital charges as in patient. Is it appropriate and legal to correct or change the coding from in patient to out patient codes after discharge? What exactly do I have to have from our Dr? I would appreciate any information anyone. Thank You!
