About the Q71 Code Range
These upper-limb differences are present at birth and include missing or shortened parts of the arm and hand.
Q71.0 describes a completely absent upper limb. Q71.1 describes an absent upper arm and forearm with the hand present. Q71.2 describes absence of the forearm and hand, while Q71.3 describes absence of the hand and finger.
Q71.4 and Q71.5 distinguish defects of the radius and ulna, the forearm bones. Q71.6 identifies lobster-claw hand. Q71.8 includes shortening and other reduction defects; Q71.9 identifies an unspecified reduction defect. Subdivisions also distinguish right, left, both, or unspecified sides.
