Complete physeal arrest, right distal femur

This code signifies the premature and complete cessation of growth at the growth plate (physis) located at the lower end of the right thigh bone. This condition prevents further longitudinal bone growth in the affected limb, potentially leading to limb length discrepancy and angular deformities.

Apply this code when documentation explicitly states a "complete physeal arrest" or "growth plate fusion" specifically affecting the distal physis of the right femur. Supporting documentation often includes radiographic reports confirming epiphyseal closure and clinical notes detailing growth cessation in the specified anatomical location.

• Ensure the documentation specifies "complete" arrest; partial arrest codes are distinct.
• Verify laterality (right) and anatomical site (distal femur) are clearly documented.
• Consider co-occurring conditions such as limb length discrepancy (M21.6X) or angular deformity (M21.0X) if also present and documented.
