Other reduction defects of left upper limb

This code signifies a congenital anomaly characterized by an incomplete development or absence of a portion of the left upper limb, not otherwise specified. This includes various forms of hypoplasia, aplasia, or other structural deficiencies affecting the arm, forearm, or hand on the left side.

Use this code for patients diagnosed with a congenital reduction defect of the left upper limb that does not fit more specific categories (e.g., longitudinal or transverse reduction defects). Documentation should clearly indicate a congenital origin and specify the left upper limb as the affected side, without further detailed classification of the defect type.

• Ensure documentation specifies "left" upper limb; otherwise, an unspecified or bilateral code may be more appropriate.
• Avoid using this code if a more specific reduction defect code (e.g., Q71.12, Q71.22) can be assigned based on the clinical details.
• Always review the entire Q71 category to ensure the most precise code is selected based on the type and laterality of the limb reduction defect.
