Ankylosis, left shoulder

This code signifies the pathological fusion or stiffening of the left shoulder joint, resulting in a significant loss of range of motion. This condition can arise from various causes, including chronic inflammation, trauma, or degenerative processes, leading to immobility and functional impairment of the affected shoulder.

Use this code when documentation explicitly states ankylosis of the left shoulder joint. This typically applies to patients presenting with a fixed, immobile left shoulder due to bony fusion or severe fibrous adhesion. Supporting documentation should include physician notes detailing the diagnosis, physical examination findings confirming the lack of motion, and potentially imaging reports (e.g., X-ray) demonstrating joint fusion.

• Ensure the documentation specifies "ankylosis" and not just severe stiffness or contracture, as these are distinct conditions.
• Verify the laterality is clearly documented as "left shoulder" to avoid incorrect coding.
• Consider co-reporting underlying conditions that led to the ankylosis, such as rheumatoid arthritis or post-traumatic arthritis, if documented.
