Assault by unspecified larger firearm discharge, sequela

This code describes the long-term effects or complications arising from an injury sustained due to an assault involving an unspecified larger firearm. It indicates that the initial injury has healed, but the patient is still experiencing residual problems directly attributable to the original incident.

This code is appropriate when a patient presents for treatment of a current condition that is a direct consequence of a past assault by an unspecified larger firearm. Examples include chronic pain, nerve damage, scar tissue complications, or psychological sequelae (e.g., PTSD) directly linked to the original injury. It should be used for encounters occurring after the initial acute treatment phase of the injury.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past assault by an unspecified larger firearm.
• Do not use this code for the initial acute injury or for follow-up care during the healing phase.
