Nondisp commnt fx shaft of ulna, unsp arm, 7thP

This code signifies a comminuted fracture of the ulna shaft that is not displaced, located in an unspecified arm. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, which has unfortunately healed incorrectly, resulting in a malunion.

Apply this code when documenting a patient's visit for ongoing management of a previously diagnosed comminuted ulnar shaft fracture that has healed with malunion. This would include scenarios such as evaluating the functional impact of the malunion, planning corrective surgery, or monitoring conservative management of the malunion.

• Ensure documentation clearly states "malunion" and specifies the "ulna shaft" and "comminuted" nature of the fracture.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm that the fracture is described as "nondisplaced" and the arm is "unspecified" if not explicitly documented as left or right.
