Nondisp transcondy fx l humerus, subs for fx w malunion

This code signifies a left humerus fracture that extends across the condyles, but the bone fragments are still in their normal anatomical position. It indicates that the patient is in a subsequent phase of care, and the fracture is healing improperly, resulting in malunion.

Use this code when documenting follow-up care for a patient who previously sustained a nondisplaced transcondylar fracture of the left humerus. This is specifically for encounters where the physician has identified that the fracture is healing with an unacceptable alignment or deformity.

• Ensure documentation clearly states "malunion" and specifies the left humerus.
• Verify the fracture was initially nondisplaced and transcondylar.
• This code is for subsequent encounters, not the initial treatment of the fracture.
