Final answer:
In the outpatient setting, a diagnosis that is documented as ''rule-out'' should be coded as if it exists.

In the outpatient setting, when a diagnosis is documented as ''rule-out'', it means that the healthcare provider suspects a particular condition but further testing is needed to confirm the diagnosis. It is important to note that in coding, a ''rule-out'' diagnosis should be coded as if it exists. Therefore, the statement is True.
