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

This code signifies a fracture at the top portion of the humerus (upper arm bone) that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates 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 issue.

Use this code for a patient who has previously been diagnosed with a nondisplaced fracture of the proximal humerus and is now being seen for management of a confirmed nonunion. This would apply to encounters where treatment for the nonunion is being planned, initiated, or monitored, such as follow-up appointments after initial casting or surgery, or when considering further interventions.

• Ensure documentation clearly states "nonunion" and specifies the "upper end" or "proximal" humerus.
• Verify that the fracture was initially nondisplaced; if displaced, a different code would be appropriate.
• This is a "subsequent encounter" code, so it should not be used for the initial treatment of the fracture.
