Juvenile osteochondrosis of proximal tibia, unspecified leg

This code signifies a developmental disorder affecting the growth plate (epiphysis) at the proximal end of the tibia in a juvenile patient, where the specific leg involved is not documented. It involves a disturbance in the normal process of bone formation, leading to fragmentation or necrosis of the bone and cartilage. This condition is often associated with pain, swelling, and functional limitations in the affected knee.

Use this code when documentation indicates juvenile osteochondrosis of the proximal tibia, but the medical record does not specify whether it affects the right or left leg. This diagnosis is typically made based on clinical examination, patient history, and imaging studies such as X-rays or MRI. Supporting documentation should clearly state the diagnosis of osteochondrosis affecting the proximal tibia in a pediatric or adolescent patient.

• Ensure the documentation explicitly states "unspecified leg" or lacks laterality information for the proximal tibia.
• Distinguish from osteochondrosis affecting other sites of the tibia (e.g., tibial tuberosity, which is Osgood-Schlatter disease).
• Always query the provider for laterality if not specified, as more specific codes (M92.511, M92.512) are available.
