Pseudocoxalgia, right hip

This code identifies Legg-Calvé-Perthes disease affecting the right hip. It describes avascular necrosis of the femoral head in children, leading to collapse and deformity of the hip joint. This condition results from an interruption of blood supply to the epiphysis of the femur.

Use this code for a confirmed diagnosis of Legg-Calvé-Perthes disease specifically impacting the patient's right hip. Documentation should clearly state the diagnosis and laterality, often supported by imaging findings (e.g., X-rays, MRI) demonstrating femoral head changes. This code is applicable for initial diagnosis and subsequent encounters related to the management of the right-sided condition.

• Ensure documentation specifies "right hip" to avoid laterality errors.
• Do not confuse with other forms of avascular necrosis or congenital hip disorders.
• Consider sequencing this code as the primary diagnosis when it is the focus of the encounter.
