Oth fracture of shaft of r humerus, subs for fx w nonunion

This code signifies a fracture located in the shaft of the right humerus, excluding specific types like supracondylar or intercondylar. The "nonunion" aspect indicates that the bone fragments have failed to heal together after a typical healing period, requiring further medical intervention.

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment for a right humeral shaft fracture that has been diagnosed as nonunion. This includes follow-up appointments, evaluations for surgical intervention to address the nonunion, or management of complications related to the nonunion.

• Always confirm the laterality (right) and the specific bone involved (humerus shaft).
• Ensure documentation clearly states "nonunion" to justify the 7th character "K".
• This code is for subsequent encounters; an initial encounter for the fracture would use a different 7th character.
