Displaced transcondy fx unsp humerus, subs for fx w malunion

This code signifies a fracture that extends through the humeral condyles, where the bone fragments are not properly aligned, and the patient is receiving ongoing treatment for a complication of healing. Specifically, the fracture has healed in an abnormal position, leading to functional impairment or deformity. The affected humerus (upper arm bone) is not specified as left or right.

Apply this code when documenting follow-up care for a patient previously diagnosed with a transcondylar humerus fracture that has healed with malunion. This includes scenarios where the patient is undergoing physical therapy, further imaging, or considering surgical intervention to correct the malunion. This code is appropriate for any encounter after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" as the complication of healing for a previously treated fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture or a new injury.
• Do not use this code if the laterality (left or right humerus) is specified in the medical record; a more specific code would be required.
