Intentional self-harm by machine gun discharge, subs encntr

This code signifies an injury resulting from a self-inflicted wound caused by a machine gun, where the patient is receiving follow-up care after the initial treatment. It indicates that the patient intentionally harmed themselves using this specific type of firearm. The "subsequent encounter" aspect means the patient is being seen for complications, healing, or ongoing management related to the original self-harm event.

Use this code when documenting follow-up visits for a patient who previously sustained injuries from intentionally discharging a machine gun upon themselves. This includes scenarios such as wound care, infection management, psychological evaluation, or physical therapy related to the initial self-harm incident. It is appropriate for any encounter after the initial acute treatment of the injury.

• Always assign an external cause code for the intent (e.g., T14.91XA for self-harm, unspecified injury).
• Ensure the "subsequent encounter" seventh character is appropriate for the patient's current stage of care.
• Code any associated injuries or conditions resulting from the machine gun discharge (e.g., fracture, organ damage).
