Discharge of firework, subsequent encounter

This code indicates an injury sustained from the discharge of a firework, specifically when the patient is seen for follow-up care after the initial treatment. This could involve complications, wound checks, or further management related to the original firework-related trauma.

Apply this code when a patient presents for a subsequent visit concerning an injury initially caused by a firework's discharge. Examples include a patient returning for a dressing change for a burn from a firework, evaluation of an infection in a wound caused by a firework, or follow-up for vision impairment resulting from a firework explosion.

• Always pair this code with an external cause code (X00-X08) to specify the type of firework.
• Ensure a corresponding injury code (e.g., burn, laceration, foreign body) is also reported to describe the specific nature of the injury.
• Verify that the encounter documented is indeed a subsequent visit for the firework injury, not the initial treatment.
