Asphyx due to smothering under pillow, self-harm, sequela

This code signifies a long-term consequence or complication arising from an intentional act of self-harm where the individual caused asphyxiation by smothering themselves with a pillow. It indicates that the patient is now presenting with a residual condition directly attributable to that past event.

Apply this code when documenting a current health problem that is a direct result of a previous self-inflicted asphyxiation by smothering under a pillow. This would be used in follow-up encounters for conditions such as anoxic brain injury, chronic respiratory issues, or other lasting physical or neurological damage stemming from the original self-harm attempt.

• This code is for sequelae only; do not use for the initial injury or acute phase.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., anoxic brain damage).
• Ensure documentation clearly links the current condition to the past self-harm event and specifies the mechanism of injury.
