Asphyxiation due to hanging, assault, subsequent encounter

This code signifies a diagnosis of asphyxiation resulting from hanging, specifically in the context of an assault. It indicates that the patient is in the recovery phase or receiving ongoing treatment for injuries sustained during the initial event, rather than the initial acute presentation.

Use this code for follow-up encounters when a patient is being treated for complications or sequelae directly related to an assault by hanging. This includes subsequent hospitalizations, outpatient visits for rehabilitation, or ongoing management of physical or psychological trauma.

• Always assign an external cause code (e.g., X91.XXXA) to fully describe the circumstances of the assault.
• Ensure the seventh character "D" (subsequent encounter) is appropriate for the patient's current phase of care.
• Code any associated injuries or psychological conditions separately and in addition to this code.
