Intentional self-harm by exposure to extremes of cold, subs

This code signifies a diagnosis where a patient has intentionally harmed themselves by exposure to extremely low temperatures, and this encounter represents follow-up care or a subsequent visit related to that initial self-harm incident. This could involve conditions like frostbite, hypothermia, or other cold-induced injuries resulting from a deliberate act. The "subsequent encounter" indicates that the patient is receiving ongoing treatment or evaluation for the sequelae of the original event.

Apply this code when documenting follow-up appointments for patients who previously presented with injuries sustained from intentional self-exposure to extreme cold. This includes visits for wound care, monitoring of cold-related complications, or mental health evaluations after the initial acute phase. It is appropriate for any encounter after the initial treatment of the self-harm event.

• Ensure documentation clearly states the self-harm was intentional and due to cold exposure.
• Verify that this is not the initial encounter for the injury; use the appropriate "initial encounter" code for the first visit.
• Always code any associated cold-related injuries (e.g., frostbite, hypothermia) in addition to this external cause code.
