In a hospital setting when a dr. does surgery on a patient can he use a rule out code as his diagnosis. Example dr. codes pt with Brain Neoplasm But patient has a brain parenchyma no malignancy identified after pathology. But the surgery was already billed with the 191.1 Is it ok to bill rule out DX and if not when can you bill rule out Diagnosis and what to do in this case.
Thanks
