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.
In these types of cases, when the proximate diagnosis is the main reason for home care, it is reported as the primary diagnosis and the underlying condition is a secondary diagnosis. Occasionally the proximate diagnosis is taken from Chapter 16 symptom codes, as in the abnormality of gait example above.
