Displ oblique fx shaft of unsp ulna, 7thM

This code signifies a specific type of ulna fracture located in the shaft, characterized by an oblique break that is displaced. It indicates that the fracture was initially an open fracture (Type I or II) and is now experiencing nonunion, meaning it has failed to heal properly. The "subsequent encounter" aspect denotes that this code is used for follow-up care related to the ongoing management of this unhealed fracture.

This code is appropriate for documenting follow-up visits where a patient is being treated for a previously sustained open, displaced oblique shaft fracture of the ulna that has not healed. This includes scenarios where surgical intervention for nonunion is being planned or has been performed, or when conservative management for the nonunion is ongoing. It should be used when the focus of the encounter is on the persistent nonunion of this specific fracture.

• Ensure documentation clearly states "nonunion" and specifies the fracture as an open, displaced oblique shaft fracture of the ulna.
• Verify that the encounter is for subsequent care, not the initial treatment of the acute fracture.
• Confirm the laterality (left, right, or unspecified) of the ulna fracture if available in the medical record.
