Nondisp transverse fx shaft of r ulna, 7thK

This code describes a situation where a patient has a transverse fracture of the shaft of their right ulna that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone has failed to heal properly after a typical healing period.

This code is appropriate for documenting ongoing treatment for a right ulnar shaft fracture that has not united, such as during clinic visits for cast changes, physical therapy, or surgical planning for nonunion repair. It should be used when the initial treatment has concluded and the focus is on managing the delayed or failed healing process.

• Ensure documentation clearly states "right ulna," "transverse fracture," "nondisplaced," and "nonunion."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Pair with external cause codes (V, W, X, Y) if the cause of the injury is known and relevant to the encounter.
