Juvenile osteochondrosis of radius and ulna, unspecified arm

This code describes a developmental disorder affecting the growth plates (epiphyses) of the radius and ulna in children and adolescents, leading to disruption of normal bone formation. It is characterized by avascular necrosis and subsequent reossification, often presenting as pain, swelling, and limited range of motion in the forearm. The "unspecified arm" indicates that the laterality (left or right) is not documented.

Use this code when documentation confirms a diagnosis of juvenile osteochondrosis specifically affecting the radius and ulna, and the medical record does not specify which arm is affected. This diagnosis is typically made based on clinical examination, patient history, and imaging studies such as X-rays or MRI.

• Ensure the documentation explicitly states "juvenile osteochondrosis" and specifies involvement of the "radius and ulna."
• If laterality (left or right arm) is documented, a more specific code should be used.
• Do not confuse with other forms of osteochondrosis affecting different bones or with adult osteochondrosis.
