Juvenile osteochondrosis of upper extremity

This code represents a group of disorders characterized by the disruption of blood supply to the epiphysis of bones in the upper extremity during childhood or adolescence, leading to avascular necrosis and subsequent bone remodeling. These conditions are often self-limiting but can cause pain, deformity, and functional impairment.

Use this code for diagnoses of osteochondrosis affecting bones such as the humeral head (e.g., Panner's disease), capitellum (e.g., osteochondritis dissecans of the elbow), or carpal bones (e.g., Kienböck's disease in its juvenile form). Documentation should clearly indicate the specific upper extremity bone involved and the diagnosis of osteochondrosis.

• Specify the exact anatomical site of the osteochondrosis when possible, as more granular codes may exist within the ICD-9-CM hierarchy for specific conditions (e.g., 732.5 for osteochondritis dissecans).
• Ensure documentation differentiates juvenile osteochondrosis from other forms of osteonecrosis or traumatic injuries.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is an co-existing condition impacting treatment.
