Other juvenile osteochondrosis of hip and pelvis, left leg

This code signifies a non-specific osteochondrosis affecting the left hip and/or pelvis in a juvenile patient, excluding Legg-Calvé-Perthes disease or slipped capital femoral epiphysis. It involves a disturbance of bone growth at the epiphysis or apophysis, leading to avascular necrosis or abnormal ossification. This condition typically presents with pain, limping, and restricted range of motion in the affected hip.

Use this code for documented cases of juvenile osteochondrosis of the left hip or pelvis that do not fit the criteria for more specific osteochondroses like Legg-Calvé-Perthes. Documentation should clearly indicate the left side and rule out other specific hip conditions. This code is appropriate when the physician's diagnosis explicitly states "other juvenile osteochondrosis of hip and pelvis, left."

• Ensure the documentation specifies "left" to support laterality.
• Differentiate from Legg-Calvé-Perthes disease (M91.1-) and slipped capital femoral epiphysis (M91.2-), which have their own specific codes.
• Confirm the patient's age aligns with "juvenile" presentation; typically, this refers to children and adolescents.
