Oth nondisp fx of low end unsp humer, subs for fx w nonunion

This code signifies a fracture at the lower part of the humerus that is not displaced and the specific side (left or right) is not documented. The key aspect is that the fracture has failed to heal properly, leading to a nonunion, and the patient is presenting for follow-up care related to this ongoing healing complication.

Apply this code when a patient with a previously diagnosed, nondisplaced fracture of the unspecified distal humerus is seen for treatment or evaluation of a confirmed nonunion. This typically involves patients undergoing further interventions or management strategies due to the lack of bone healing.

• Ensure documentation clearly states "nonunion" for the fracture.
• Confirm the encounter is for subsequent care, not the initial treatment.
• Use this code when the laterality of the humerus is not specified in the medical record.
