Other reduction defects of upper limb, bilateral

This code signifies the presence of various congenital malformations affecting both upper limbs, characterized by a reduction in the normal development of bone or soft tissue, excluding specific types of reduction defects classified elsewhere. These defects can range from hypoplasia of bones to complete absence of parts of the limb.

Apply this code when documentation clearly indicates a congenital reduction defect affecting both the right and left upper extremities, and the specific type of defect is not precisely categorized by more specific codes within the Q71 series. Supporting documentation should detail the nature and bilaterality of the limb anomaly.

• Ensure the documentation explicitly states the defect affects both upper limbs.
• Review other Q71 subcategories to confirm this code is the most appropriate for the specific reduction defect described.
• Consider sequencing this code after any associated syndromes or genetic conditions if applicable.
