Complete physeal arrest, left proximal femur

This code signifies the complete cessation of growth plate activity in the proximal portion of the left femur. This condition results in a permanent shortening of the affected limb due to the premature fusion of the physis, preventing further longitudinal bone growth.

Apply this code when documentation explicitly states a "complete physeal arrest" affecting the left proximal femur. This typically occurs following trauma, infection, or metabolic disorders that damage the growth plate, leading to its premature closure. Supporting documentation includes imaging reports (X-rays, MRI) confirming growth plate fusion and clinical notes detailing growth discrepancies.

• Differentiate from partial physeal arrest, which would require a different code.
• Ensure the laterality (left) and bone (femur) are accurately documented.
• Consider sequencing this code as a secondary diagnosis if an underlying cause (e.g., fracture, infection) is still being treated.
