Juvenile osteochondrosis of metatarsus, right foot

This code identifies a developmental disorder affecting the growth plates of the metatarsal bones in the right foot of a juvenile patient. It involves the disruption of normal bone growth due to avascular necrosis, leading to pain, swelling, and potential deformity in the forefoot. This condition is often referred to as Freiberg's disease when it affects the second metatarsal head.

Apply this code when documentation specifies osteochondrosis impacting any metatarsal bone in the patient's right foot, particularly in pediatric or adolescent populations. Supporting documentation should include a definitive diagnosis from a physician, often based on clinical examination and imaging studies such as X-rays or MRI.

• Ensure the documentation specifies "right foot" to accurately assign this laterality-specific code.
• Distinguish from other foot osteochondroses, such as Kohler's disease (navicular) or Sever's disease (calcaneus), which have distinct codes.
• Verify the patient's age aligns with the "juvenile" aspect of the diagnosis; this code is typically not appropriate for adult-onset conditions.
