Assault by other larger firearm discharge, subs encntr

This code describes an injury resulting from an assault involving a larger firearm, such as a rifle or shotgun, where the patient is presenting for follow-up care after the initial treatment of the injury. It indicates that the injury was intentionally inflicted by another person using a substantial firearm.

Use this code when documenting subsequent encounters for a patient who sustained injuries from an assault by a larger firearm. This includes visits for wound care, physical therapy, medication management, or evaluation of complications related to the initial firearm injury. It is appropriate for any visit after the initial acute treatment.

• Ensure the documentation clearly specifies "assault" and "larger firearm" to support code assignment.
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the specific injury(ies) resulting from the firearm discharge first, followed by this external cause code.
