Unequal limb length (acquired), right femur

This code signifies an acquired discrepancy in the length of the lower limbs, specifically affecting the right femur. This condition, often referred to as leg length discrepancy (LLD), develops after birth due to various factors, leading to an observable difference in the length of the right thigh bone compared to the left. It can result in gait abnormalities, pelvic tilt, and compensatory spinal curvature.

Use this code when documentation clearly indicates an acquired unequal limb length where the right femur is identified as the primary source of the discrepancy. This diagnosis is supported by physical examination findings, radiographic measurements (e.g., scanogram, orthoroentgenogram), or patient history detailing a post-natal onset of the length difference.

• Differentiate from congenital limb length discrepancy; this code is strictly for acquired conditions.
• Ensure documentation specifies "right femur" as the anatomical site of the length difference.
• Consider sequencing with codes for underlying causes (e.g., fracture malunion, osteomyelitis, tumor) if applicable.
