Ankylosis, left elbow

This code signifies the pathological fusion or stiffening of the left elbow joint, resulting in significant loss of range of motion. This immobility can be caused by various underlying conditions, including severe arthritis, trauma, or infection, leading to a rigid joint.

Apply this code when documentation clearly indicates a diagnosis of ankylosis affecting the left elbow. This typically occurs in patients presenting with a fixed, non-mobile left elbow joint, often confirmed by physical examination and imaging studies.

• Ensure laterality (left elbow) is explicitly documented to support this specific code.
• Do not confuse with arthrofibrosis or contracture, which imply restricted motion but not complete fusion.
• Code any underlying cause of the ankylosis (e.g., rheumatoid arthritis, fracture sequela) as an additional diagnosis.
