Syndactyly (Q70)
ICD-10 code Q70 covers syndactyly, a congenital condition involving fusion or webbing of fingers or toes. It categorizes various forms of syndactyly, specifying whether the fusion is bony (fused) or skin-only (webbed), and identifies which hand or foot is affected.
Syndactyly includes conditions commonly called fused fingers (Q70.0) or webbed fingers (Q70.1), and similarly for toes (Q70.2 and Q70.3). For instance, Q70.00 refers to osseous syndactyly of the fingers on an unspecified hand, encompassing terms like "acrosyndactyly of thumb" or "congenital bony fusion of phalanges." Codes further specify right, left, or bilateral involvement. The code Q70.4 relates to polysyndactyly (extra fused digits), while Q70.9 is used for unspecified syndactyly types. These distinctions help medical coders accurately assign the ICD-10 code for syndactyly variants based on the precise presentation, facilitating clear documentation and data tracking for congenital musculoskeletal anomalies.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Poland Syndrome
A syndrome which is characterized by symbrachydactyly and aplasia of the sternal head of pectoralis major.
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.
