Accidental handgun discharge, sequela

This diagnosis code signifies the long-term effects or complications arising from an accidental discharge of a handgun. It is used to report conditions that are residual or follow as a consequence of the initial injury, rather than the acute event itself. These sequelae can include chronic pain, nerve damage, scarring, or functional limitations.

This code is appropriate for encounters where a patient is being treated for a condition that is a direct result of an accidental handgun discharge that occurred in the past. Examples include follow-up visits for ongoing physical therapy due to a permanent disability, surgical correction of deformities, or management of chronic pain stemming from the original injury. It should be used after the acute phase of the injury has passed.

• Always sequence this sequela code after the code(s) identifying the specific nature of the sequela (e.g., chronic pain, scar, nerve damage).
• Ensure documentation clearly links the current condition to the past accidental handgun discharge.
• Do not use this code for the initial treatment of the acute injury; instead, use the acute injury code with the appropriate seventh character.
