Bennett's fracture, right hand, subs for fx w malunion

This code signifies a Bennett's fracture of the right hand that has previously been treated but has healed in an anatomically incorrect or misaligned position. Malunion indicates that the bone fragments have united, but the alignment is suboptimal, potentially leading to functional impairment or pain. This is a subsequent encounter, meaning the patient is presenting for follow-up care related to this malunited fracture.

Use this code when a patient presents for evaluation or treatment of a malunited Bennett's fracture of the right hand, after the initial treatment phase. This would include scenarios where a patient is experiencing ongoing symptoms due to the malunion, or is being assessed for corrective surgery. It is appropriate for follow-up appointments where the malunion is the primary focus of the visit.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or delayed healing.
• Verify the fracture is specifically a Bennett's fracture and located in the right hand.
• Confirm this is a subsequent encounter, indicating the initial fracture treatment has already occurred.
