Congenital shortening of left upper limb

This code signifies a birth defect characterized by an abnormally reduced length of the left arm, forearm, or hand. This shortening is present at birth and can range from mild hypoplasia to complete absence of a segment. It impacts the overall function and appearance of the affected limb.

Assign this code for congenital conditions where the left upper limb is definitively documented as shorter than normal. This typically includes diagnoses such as radial club hand, ulnar club hand, or phocomelia affecting the left side. Documentation should clearly specify the congenital nature and the laterality of the limb shortening.

• Ensure documentation specifies "congenital" and "left upper limb" to support this code.
• Distinguish from acquired shortening due to trauma or disease, which would use different codes.
• Code any associated malformations or syndromes separately, if applicable.
