Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q70 range.
Polysyndactyly
A rare anatomical malformation characterized by polydactyly (extra fingers or toes) and syndactyly (webbed fingers or toes).
Syndactyly
A congenital anomaly of the hand or foot, marked by the webbing between adjacent fingers or toes. Syndactylies are classified as complete or incomplete by the degree of joining. Syndactylies can also be simple or complex. Simple syndactyly indicates joining of only skin or soft tissue; complex syndactyly marks joining of bony elements.
About the Q70 Code Range
Syndactyly is a condition present at birth in which adjacent fingers or toes are joined by webbing.
The subdivisions distinguish fused fingers (Q70.0), webbed fingers (Q70.1), fused toes (Q70.2), and webbed toes (Q70.3). Each group then identifies the right side, left side, both sides, or an unspecified side. The remaining subdivisions are unspecified polysyndactyly (Q70.4) and unspecified syndactyly (Q70.9).
