Osteochondritis dissecans, unspecified wrist

This code describes a condition where a segment of bone and its overlying cartilage in the wrist loses its blood supply and separates from the surrounding bone. This can lead to pain, swelling, and mechanical symptoms like clicking or catching in the wrist joint. It represents an unspecified location within the wrist.

Use this code when documentation confirms osteochondritis dissecans affecting the wrist, but the specific carpal bone or joint involved is not clearly identified. This diagnosis is typically made based on imaging studies such as X-rays, MRI, or CT scans, in conjunction with clinical findings.

• Avoid using this code if the specific carpal bone or joint affected by osteochondritis dissecans is documented; instead, use a more specific code from the M93.23- subcategory.
• Always review imaging reports and physician notes for precise anatomical location to ensure the highest level of specificity.
• Consider sequencing this code after any traumatic injury codes if the osteochondritis dissecans is a sequela of trauma.
