Bent bone of right ulna, sequela

This code signifies a permanent deformity of the right ulna, specifically a bent or malformed bone, resulting from a previous injury or condition. It indicates that the acute phase of the original injury has passed, and the current presentation is a long-term consequence.

Apply this code when documenting a patient presenting with a chronic, non-acute angulation or curvature of the right ulna that is a direct sequela of a past fracture, osteomyelitis, or other bone-altering event. This is appropriate for follow-up visits addressing the long-term impact of the deformity.

• Always assign an additional code to identify the original cause of the bent ulna, if known and still relevant for medical necessity.
• Ensure documentation clearly states the bent ulna is a sequela, indicating a healed or chronic condition rather than an acute injury.
• Verify laterality (right ulna) is explicitly documented to support the use of this specific code.
