The  Principal Diagnosis  (PDX) for inpatient care is defined as that condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.
The first-listed diagnosis is reported by physician offices, ambulatory care centers, outpatient hospital settings, and so on. In an inpatient setting, the term Primary Diagnosis is still used to reference the condition that was the most serious and/or resource intensive during that hospitalization.
