Partial physeal arrest, left proximal femur

This code signifies an incomplete cessation of growth at the growth plate (physis) in the upper part of the left thigh bone. This condition can lead to limb length discrepancies or angular deformities as the bone continues to grow unevenly. It typically results from trauma, infection, or other insults to the physis during childhood or adolescence.

Use this code for patients diagnosed with a partial growth arrest affecting the proximal physis of the left femur. Documentation should clearly state the laterality (left), the specific bone (femur), the location (proximal), and confirm the partial nature of the physeal arrest. Imaging reports (e.g., X-rays, MRI) confirming the physeal bar or growth plate irregularity are crucial for supporting this diagnosis.

• Ensure documentation specifies "partial" arrest; a complete arrest would use a different subcategory.
• Verify laterality (left) and the specific bone (femur) and location (proximal) are clearly documented.
• Do not confuse with epiphyseal fractures without growth arrest, or other growth disturbances like osteochondroses.
