Displ seg fx shaft of ulna, l arm, 7thQ

This code describes a specific type of healing complication for a left ulna shaft fracture. It indicates that the fracture was initially an open fracture (Type I or II) and has subsequently developed malunion, meaning it has healed in an incorrect or deformed position. This is an encounter for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient with a previously treated open fracture of the left ulna shaft presents with documented malunion. It would be used when the patient is receiving ongoing management, evaluation, or treatment for the malunion itself, rather than the initial acute injury. This would include follow-up appointments after initial treatment, or when planning for corrective procedures.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing," as these have different codes.
• Verify the laterality (left arm) and the specific bone (ulna shaft) are accurately documented.
• Confirm the original fracture was an "open fracture type I or II" as this is a specific component of the code.
