Nondisp fx of neck of unsp MC bone, subs for fx w malunion

This code signifies a previously sustained fracture of the neck of an unspecified metacarpal bone that is now healing improperly, resulting in a malunion. The fracture itself was initially nondisplaced, meaning the bone fragments remained in their anatomical alignment at the time of injury. This code is used during follow-up care for this specific complication.

This code is appropriate for documenting subsequent encounters where a patient is being treated for a malunion of a nondisplaced metacarpal neck fracture. This includes follow-up appointments, physical therapy sessions, or further diagnostic imaging to assess the extent of the malunion. It indicates that the initial fracture is not yet fully healed and has developed an undesirable alignment.

• Ensure the documentation clearly specifies "malunion" as the complication of the fracture.
• Verify that the initial fracture was indeed nondisplaced and located in the neck of a metacarpal.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
