Accidental handgun malfunction, sequela

This code describes the long-term effects or complications arising from an accidental malfunction of a handgun. It indicates that a previous incident involving a firearm's mechanical failure has resulted in ongoing health issues for the patient.

Apply this code when documenting conditions such as chronic pain, nerve damage, scarring, or psychological sequelae (e.g., PTSD) that are directly attributable to an accidental handgun malfunction that occurred in the past. This code is used after the acute phase of the injury has passed and the patient is receiving treatment for residual problems.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past accidental handgun malfunction.
• Do not use this code for initial encounters or acute injuries; it is specifically for residual effects.
