Assault by other firearm discharge, subsequent encounter

This code signifies an injury resulting from an assault involving a firearm, where the specific type of firearm is not otherwise specified, and the patient is receiving follow-up care for the initial injury. This includes situations where the patient is seen for routine follow-up, healing complications, or further treatment after the initial acute phase of care.

Use this code for subsequent encounters when a patient presents for ongoing management of injuries sustained from an assault by an unspecified firearm. This applies to visits for wound care, physical therapy, medication adjustments, or monitoring of recovery from the initial firearm discharge. It is appropriate for any encounter after the initial treatment of the acute injury.

• Always assign an external cause code for the initial injury (e.g., T-code for the specific injury) in conjunction with this code.
• Ensure the seventh character "D" is correctly applied to indicate a subsequent encounter.
• Verify that the documentation clearly states the injury is a result of an assault and that the encounter is not for the initial treatment.
