Unequal limb length (acquired), left radius

This code describes an acquired disparity in the length of the left radius bone, meaning the left forearm bone is shorter or longer than its contralateral counterpart due to factors arising after birth. This can lead to functional limitations and cosmetic concerns in the affected upper limb.

Use this code when documentation clearly indicates an acquired unequal length of the left radius, often resulting from trauma (e.g., fracture malunion), infection, or surgical intervention. Supporting documentation should specify the laterality and the acquired nature of the limb length discrepancy.

• Differentiate from congenital limb length discrepancies, which are coded elsewhere.
• Ensure the documentation specifies "acquired" and "left radius" to support this specific code.
• Consider additional codes for the underlying cause of the acquired unequal length, if known and documented.
