This question is geared for coders process inpatient admissions diagnosis codes. If the hospitalist or attending physician list 4 or 5 diagnosis codes for the patient for the day of treatment with a sub hospital visit. Unspecified dx. codes can be used in the inpatient setting per the regulations. Is not the medical coder to list all of them on the claim in the proper sequence? I know DRG and POA are related together for the reason the patient arrives and got treatment thru the ER or for their inpatient status. Also I know patients treated by the medical specialist may use their dx code related to the care of of the patient in regards to their his or her professional medical specialty.

Thank you in advance
