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

This code signifies a previously treated fracture at the base of the fourth metacarpal bone in the left hand that has healed in an anatomically incorrect position (malunion). The fracture itself is not displaced, meaning the bone fragments are still aligned, but the overall healing has resulted in an abnormal angulation or rotation. This condition often leads to functional impairment and pain.

Use this code for follow-up encounters where a patient is being evaluated or treated for complications arising from a malunited fracture of the left fourth metacarpal base. This includes scenarios such as assessing range of motion limitations, persistent pain, or planning for corrective surgery due to the malunion. It indicates that the initial fracture treatment has concluded, and the current focus is on managing the sequelae of the imperfect healing.

• Ensure documentation clearly states "malunion" and specifies the "fourth metacarpal" and "left hand."
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
• Look for documentation of functional deficits or pain directly attributable to the malunion.
