Article Overview
This article covers ICD-9-CM outpatient coding guidance for diagnostic tests performed in settings such as physician offices and radiology or pathology encounters. It focuses on how interpreting physicians should approach diagnosis reporting when tests are ordered for signs or symptoms, when results confirm a condition, when results are normal, and when the referring diagnosis is uncertain. The content is aimed at medical coders, billers, and clinicians who document or report diagnostic test encounters.
