Osteochondritis dissecans, left shoulder

This code signifies a condition where a segment of bone and its overlying cartilage in the left shoulder joint loses its blood supply, leading to its eventual separation from the surrounding bone. This can result in pain, swelling, and mechanical symptoms like clicking or locking.

Use this code for documented cases of osteochondritis dissecans affecting the left shoulder. Supporting documentation should include imaging findings (e.g., X-ray, MRI) confirming the lesion's presence and location, along with clinical notes describing the patient's symptoms and physical examination findings.

• Specify laterality; this code is exclusively for the left shoulder.
• Distinguish from other osteochondroses or avascular necrosis, which have different code assignments.
• Consider additional codes for any associated complications, such as loose bodies within the joint.
