Asphyx due to being trapped in a car trunk, self-harm, subs

This code signifies a non-fatal injury resulting from a patient intentionally suffocating themselves by being confined within a car trunk. It indicates a subsequent encounter for the treatment or follow-up of this specific self-inflicted asphyxiation.

This code is appropriate for documenting follow-up care for a patient who previously attempted suicide by trapping themselves in a car trunk. Examples include managing complications, mental health evaluations, or ongoing physical therapy related to the initial incident.

• Always assign an external cause code (X72.0XXA) to further specify the intent and mechanism.
• Ensure the "D" seventh character is used only for subsequent encounters, not initial treatment.
• Consider additional codes for any associated injuries or mental health diagnoses.
