Unequal limb length (acquired), right tibia

This code signifies an acquired discrepancy in the length of the right tibia, meaning the right lower leg bone is either longer or shorter than its contralateral counterpart due to a condition developed after birth. This can lead to gait abnormalities, compensatory scoliosis, and joint pain.

Apply this code when documentation explicitly states an acquired unequal limb length affecting the right tibia. This is typically diagnosed through physical examination, radiographic measurements (e.g., scanograms), or clinical observation of gait asymmetry.

• Ensure documentation specifies "acquired" limb length inequality; congenital forms are coded differently.
• Laterality is crucial; verify the right tibia is the affected limb.
• Consider co-reporting codes for underlying causes (e.g., fracture malunion, osteomyelitis) if documented.
