Nondisp seg fx shaft of humer, r arm, subs for fx w nonunion

This code describes a fracture of the shaft of the right humerus that is broken into at least three pieces (segmental) but with the bone fragments still in their normal anatomical alignment (nondisplaced). The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" signifies that the fracture is failing to heal properly.

This code is appropriate for documenting ongoing treatment for a right humeral shaft fracture that has not healed as expected. This includes scenarios where a patient is undergoing further evaluation, conservative management, or surgical intervention specifically to address the nonunion of a previously diagnosed segmental, nondisplaced fracture. It would be used after the initial treatment phase.

• Ensure documentation clearly specifies "right arm," "segmental," and "nondisplaced" for the humerus shaft fracture.
• Confirm the encounter is for follow-up care of the fracture, not the initial treatment.
• Verify that the physician explicitly states or implies a diagnosis of "nonunion" for the fracture.
