Assault by sharp glass, subsequent encounter

This code signifies an injury resulting from an assault where sharp glass was the weapon, and the patient is presenting for follow-up care after the initial treatment of the injury. This could involve wound checks, dressing changes, or management of complications from the original assault.

Apply this code when a patient returns for subsequent care related to an injury initially sustained from an assault involving sharp glass. Examples include a patient presenting for a post-operative check of a laceration repair, evaluation of infection at the wound site, or physical therapy for residual functional impairment.

• Ensure the encounter is for follow-up care, not the initial treatment.
• Verify the mechanism of injury was explicitly "sharp glass" and not another sharp object.
• Always sequence this external cause code after the primary injury code(s).
