Does anyone know where I can find information addressing this situation? We billed 99223 with modifier 57 on the same day as 15004 (90 day global) and 15260 (10 day global). Insurance initially paid on the E&M but are now taking it back saying it cannot be used with a minor procedure (15004). I need to know if I can fight this since we also have a 90 day procedure on the claim.
