Congen absence of unsp upper arm and forearm w hand present

This code describes a birth defect characterized by the complete absence of both the upper arm (humerus) and forearm (radius and ulna) in an unspecified upper limb, while the hand itself is still present and attached directly to the shoulder girdle. This is a severe form of congenital limb deficiency affecting the proximal and intermediate segments of the upper extremity.

Use this code when documentation clearly indicates a congenital absence of both the upper arm and forearm, with the hand being present, but the specific side (left or right) is not specified. This code is appropriate for initial diagnoses and follow-up care for patients with this specific type of limb reduction defect. Supporting documentation would include genetic reports, imaging studies (e.g., ultrasound, X-ray), and detailed physical examination findings.

• Ensure the documentation explicitly states the absence of both the upper arm and forearm, with the hand present.
• Only use this code when the laterality (left or right) is truly unspecified; otherwise, use the more specific Q71.11 (right) or Q71.12 (left).
• Do not confuse with codes for congenital absence of the entire limb (e.g., Q71.3-) or absence of only a segment (e.g., Q71.2- for forearm and hand).
