Bent bone of unsp ulna, 7thE

This code signifies a fracture of the ulna where the bone has been bent or deformed, but the specific side (left or right) is not documented. It is used for follow-up care of an open fracture (Type I or II, indicating minimal skin damage) that is healing as expected.

Apply this code when a patient presents for a subsequent visit related to an open ulnar fracture that was initially described as bent, and the healing process is progressing routinely. This would typically be used after the initial treatment phase, during the period of fracture consolidation.

• Ensure documentation specifies "bent bone" and an open fracture type I or II.
• Confirm this is a subsequent encounter and healing is routine; otherwise, a different S52.28- subcategory may be more appropriate.
• Always code laterality if documented (e.g., left or right ulna) to achieve a more specific code.
