Osteochondritis dissecans, left hip

This code identifies a condition where a segment of cartilage and underlying bone in the left hip joint loses its blood supply, leading to its eventual separation from the surrounding bone. This can cause pain, swelling, and mechanical symptoms such as clicking or locking in the hip. It represents a specific form of osteochondrosis affecting the femoral head or acetabulum.

This code is appropriate for documenting a confirmed diagnosis of osteochondritis dissecans specifically affecting the left hip joint. Clinical documentation should clearly state the diagnosis and laterality, often supported by imaging findings such as X-rays, MRI, or CT scans demonstrating the characteristic lesion.

• Ensure documentation specifies "left hip" to support the laterality in the code.
• Do not confuse with other forms of osteochondrosis or avascular necrosis, which have distinct codes.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
