An outpatient assessment lists “probable pneumonia.” Applying outpatient uncertain-diagnosis guidelines, what should the physician-office coder do?
Select an answer to reveal the explanation.
Short Explanation
Outpatient world is picky: “probable” isn’t a green light to code confirmed pneumonia like inpatient sometimes allows. Stick to what’s solid—symptoms or other established diagnoses—until the clinician actually confirms it.
Full Explanation
ICD-10-CM Official Guidelines differ for inpatient versus outpatient uncertain diagnoses. In outpatient and physician-office settings, conditions documented as probable, suspected, or similar uncertain terms are not coded as if confirmed. Coders report established diagnoses or signs/symptoms to the highest certainty documented rather than omitting the entire encounter or escalating to unrelated severe diagnoses.
