Struck by baseball, subsequent encounter

This code indicates that a patient is presenting for follow-up care or treatment of an injury sustained from being hit by a baseball. The initial injury has already been addressed, and this encounter is for ongoing management, healing assessment, or complications.

Apply this code when a patient returns for a subsequent visit related to an injury caused by being struck by a baseball, such as a fractured bone, concussion, or contusion. This includes scenarios like cast changes, wound checks, physical therapy evaluations, or re-evaluations of a concussion.

• Always pair this external cause code with a primary diagnosis code detailing the specific injury sustained (e.g., fracture, contusion, concussion).
• Ensure the encounter type is clearly documented as subsequent care, not initial treatment, to justify the "D" seventh character.
• Verify that the mechanism of injury explicitly states "struck by baseball" to differentiate from other sports-related or blunt force traumas.
