What You Will Learn About Principal Diagnosis Selection
Important: Principal diagnosis rules vary by care setting. For inpatient hospital coding, determine the condition established after study as chiefly responsible for admission, then apply official conventions, chapter rules, and documentation requirements. Educational examples do not replace current official guidance.
