I am new to OP coding. I code outpatient diagnostics. I am to look for the physicians orders and code the diagnosis from it. Sometimes the diagnosis does not meet medical necessity and I have to send a referral to the department for a dx that meets MN. I guess what I am getting at is, If I have a definite diagnosis from say the test result that they ordeered, can't I just code the result? I have been told I must code what is on the order no matter what. Since I have worked in physician's offices in the past, I know that many times they just put evey dx that the patient has just in case. I am confused about the coding guidelines and the physician order. Is there a place in the coding guidlines that addresses this area?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
