Nondisp fx of prox phalanx of l mid fngr, 7thP

This code signifies a non-displaced break in the bone closest to the hand in the left middle finger, which has healed improperly. Malunion indicates that the fracture has united, but in a deformed or misaligned position, potentially affecting function.

Apply this code when a patient presents for follow-up care of a previously treated non-displaced fracture of the proximal phalanx of the left middle finger, and clinical or radiological assessment confirms that the bone has healed with a noticeable deformity or angulation. This would include scenarios where the patient is undergoing rehabilitation, further imaging, or discussing potential corrective procedures for the malunion.

• Confirm documentation explicitly states "malunion" and specifies the left middle finger, proximal phalanx.
• Ensure the encounter is for follow-up care of the fracture, not the initial treatment.
• Distinguish from nonunion (S62.643N), which indicates complete failure of bone healing.
