Nondisp fx of base of 4th MC bone, r hand, 7thP

This code signifies a healed, but imperfectly aligned, fracture at the base of the fourth metacarpal bone in the right hand. The initial break was not displaced, and the current encounter addresses the ongoing management or complications related to the bone's healing in a suboptimal position.

Apply this code for patients presenting with persistent pain, limited range of motion, or functional impairment in the right hand due to a previously sustained and now malunited fracture of the fourth metacarpal base. This is appropriate for follow-up visits where the malunion is being addressed, such as for physical therapy, re-evaluation, or surgical planning for corrective osteotomy.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for this condition.
• Verify the fracture location is precisely the "base of the fourth metacarpal" and the side is "right hand."
• Do not use this code for initial fracture treatment or for nonunion (S62.344N).
