Juvenile osteochondrosis of tibia tubercle, left leg

This code describes Osgood-Schlatter disease affecting the left knee. It is an inflammation of the patellar ligament at the tibial tuberosity, typically occurring in adolescents due to repetitive stress during growth spurts.

Use this code for a confirmed diagnosis of Osgood-Schlatter disease specifically impacting the left lower extremity. Documentation should clearly indicate the laterality and the diagnosis of juvenile osteochondrosis of the tibial tubercle.

• Ensure documentation specifies "left leg" or "left knee" to support laterality.
• Distinguish from other osteochondroses affecting different anatomical sites.
• Do not use for adult osteochondrosis; this code is specific to juvenile forms.
