Unequal limb length (acquired), right radius

This code signifies an acquired difference in length between the right radius and its contralateral counterpart. This condition is not congenital but develops after birth due to various factors affecting bone growth or integrity. It can lead to functional impairment and cosmetic concerns in the affected upper limb.

Apply this code when documentation clearly indicates an acquired shortening or lengthening of the right radius compared to the left. This typically arises from conditions such as fractures with malunion, osteomyelitis, tumors, or growth plate injuries sustained after birth. Supporting documentation should include measurements confirming the length discrepancy and a clear indication that it is not congenital.

• Ensure the documentation specifies "acquired" to differentiate from congenital limb length discrepancies.
• Verify laterality; this code is specific to the right radius.
• Code any underlying cause of the acquired unequal limb length, such as a malunion of a fracture, in addition to this code.
