Congenital absence of r up arm and forearm w hand present

This code describes a birth defect where the right upper arm and forearm are missing, but the hand is still present. This is a form of transverse limb deficiency affecting the upper extremity on the right side. The absence is congenital, meaning it was present at birth.

Use this code for patients diagnosed with a congenital absence of the right humerus and radius/ulna, while the right hand remains intact. Documentation should clearly specify the congenital nature of the defect and the specific parts of the right upper limb that are absent versus present.

• Differentiate carefully between absence of the entire limb versus specific segments; laterality is crucial.
• Do not confuse with acquired amputations or other types of limb malformations where the limb is present but deformed.
• Ensure documentation specifies "congenital" to support the use of a Q-code.
