Accidental malfunction of hunting rifle, sequela

This code signifies a long-term health problem or complication that arose from an accidental malfunction of a hunting rifle. It indicates that the initial injury has resolved, but the patient is now experiencing a residual effect or condition directly attributable to that past event. This could include chronic pain, nerve damage, scarring, or functional limitations resulting from the original firearm incident.

This code is appropriate when documenting a patient's current condition that is a sequela of a hunting rifle malfunction. For example, a patient presenting with chronic osteomyelitis in a limb previously injured by an accidental discharge, or a patient with permanent vision loss from an eye injury sustained years ago due to a rifle malfunction. It should be used in conjunction with a code describing the specific sequela.

• Always code the specific sequela first, followed by this external cause code.
• Ensure documentation clearly links the current condition to the past hunting rifle malfunction.
• The "S" in the seventh character indicates sequela, meaning the initial injury has healed and the current problem is a residual effect.
