Unequal limb length (acquired), left fibula

This code signifies an acquired disparity in the length of the lower limbs, specifically affecting the left fibula. This condition results in one leg being noticeably shorter than the other due to factors occurring after birth, impacting gait, posture, and potentially leading to secondary musculoskeletal issues.

Apply this code when documentation clearly indicates an acquired shortening of the left lower extremity, with the fibula identified as the primary anatomical site of the length discrepancy. This is typically supported by physical examination findings, radiographic measurements, and a history of a post-natal event or condition contributing to the unequal length.

• Ensure documentation specifies "acquired" as opposed to congenital limb length discrepancy.
• Verify laterality (left) and the specific bone (fibula) are explicitly stated in the medical record.
• Consider co-reporting with codes for underlying causes (e.g., fracture malunion, osteomyelitis) or associated conditions (e.g., gait disturbance, scoliosis).
