Personal history of suicidal behavior

This code indicates a patient has a documented history of attempting suicide or engaging in self-harm with suicidal intent. It signifies a past episode of suicidal behavior, regardless of the method or severity, and is distinct from current suicidal ideation or attempts.

Apply this code when a patient's medical record clearly states a prior suicide attempt or self-injurious behavior with the intent to die. This is often relevant for ongoing mental health treatment, risk assessment, or when considering medication management.

• Always sequence this code as a secondary diagnosis, following the primary mental health condition or reason for the encounter.
• Do not use this code for current suicidal ideation or active suicide attempts; those require specific codes from Chapter 5 (Mental, Behavioral and Neurodevelopmental disorders) or Chapter 20 (External causes of morbidity).
• Ensure documentation explicitly states "history of suicidal behavior" or "past suicide attempt" to support the use of this code.
