Hunting rifle discharge, undetermined intent, subs encntr

This code signifies an injury sustained from a hunting rifle discharge where the intent (accidental, self-harm, assault) cannot be determined. It is specifically for follow-up care or subsequent encounters related to the initial injury.

Apply this code when a patient presents for ongoing treatment, wound care, physical therapy, or follow-up appointments for an injury caused by a hunting rifle, and the circumstances surrounding the discharge remain unclear. This would be used after the initial acute treatment phase.

• Always assign an external cause code (Y23.1XXD) in conjunction with a code for the specific injury sustained.
• Ensure the seventh character "D" is used for subsequent encounters, indicating active treatment or recovery.
• Do not use this code for initial encounters; instead, use the appropriate "A" seventh character for the initial treatment.
