Notes: The table reports the rates per 10,000 teens.
↵^a Suicidal ideation is a symptom and is not supposed to be coded as primary if there is another confirmed diagnosis.
In Panel B, we reassign visits with a primary diagnosis of suicidal ideation and a secondary diagnosis code to make the non-SI code primary. For example, if SI is primary, but the secondary diagnosis is a mood disorder, then we count the visit in the “Mood disorder is primary” row in Panel B.
