Other firearm discharge, undetermined intent, subs encntr

This code signifies an injury or adverse effect resulting from a firearm discharge where the intent (e.g., accidental, self-harm, assault) cannot be determined. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for this initial injury, such as wound checks, physical therapy, or medication adjustments.

Apply this code when a patient presents for ongoing treatment related to a firearm injury of unknown intent. This includes situations where the initial cause of the discharge remains unclear after investigation, or when documentation explicitly states "undetermined intent" for a follow-up visit.

• Ensure documentation clearly supports "undetermined intent" for the firearm discharge.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific nature of the firearm injury (e.g., gunshot wound to the abdomen) as the primary diagnosis.
