Bent bone of left ulna, sequela

This code signifies a long-term or late effect of a previous injury to the left ulna, specifically where the bone has healed in a bent or angulated position. This deformity is not a new fracture but a residual complication from an earlier trauma.

Apply this code when documenting a patient presenting with an established, non-acute angulation or bowing of the left ulnar shaft due to a prior injury. This is appropriate for follow-up visits addressing the chronic deformity, its complications, or for surgical planning related to correcting the malunion.

• Always sequence this code after the code for the original injury, if still active, or as a primary diagnosis if the sequela is the primary reason for the encounter.
• Ensure documentation clearly states "sequela" or "late effect" and specifies the left ulna and the bent bone characteristic.
• Do not use this code for acute fractures or malunions that are still actively healing.
