Intentional self-harm by oth larger firearm discharge, subs

This code signifies a follow-up encounter for an injury resulting from a deliberate act of self-harm using a large firearm, such as a rifle or shotgun. It indicates that the patient is receiving ongoing treatment or evaluation for the physical and/or psychological consequences of this self-inflicted injury. The "subsequent encounter" aspect means the initial treatment for the acute injury has already occurred.

This code is appropriate for any visit after the initial treatment of a self-inflicted gunshot wound from a large firearm. This includes follow-up appointments for wound care, surgical revisions, physical therapy, psychiatric evaluation, or management of complications arising from the original injury. It should be used when the patient is seen for continued care related to the self-harm event.

• Ensure documentation clearly states "self-harm" or "intentional" and specifies a "larger firearm" (e.g., rifle, shotgun).
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Always code associated injuries (e.g., fracture, organ damage) in addition to this external cause code.
