2025 ICD-10-CM code Q70
(Active) Effective Date: N/A Congenital malformations, deformations and chromosomal abnormalities - Q65-Q79 Q00-Q99 Feed
Syndactyly (fusion of fingers or toes).
Medical necessity for treatment (e.g., surgery) is determined by the severity of the syndactyly and its impact on hand/foot function, potential for future growth, and psychosocial well-being. Simple syndactyly may not require treatment if function is not impaired.
Diagnosis and management of this condition is typically overseen by pediatricians, geneticists, and/or orthopedic surgeons, depending on the complexity and need for surgical intervention.
In simple words: Syndactyly is a birth defect where fingers or toes are joined or webbed together.
Syndactyly is a condition where two or more digits (fingers or toes) are fused. It can range from simple webbing of the skin to complex fusion of bones.
Example 1: A newborn infant is noted to have webbing between the middle and ring fingers of their left hand. This simple syndactyly is documented as Q70.1., A child presents with complete fusion of the bones in the second and third toes of the right foot. This complex syndactyly is classified under Q70.2., A fetus is diagnosed prenatally with multiple finger and toe fusions. Unspecified syndactyly (Q70.9) is used until a more detailed postnatal evaluation can be performed.
Documentation should specify the type of syndactyly (simple/complex, complete/incomplete), the affected digits, laterality (left, right, or bilateral), and any associated anomalies.
** For prenatal diagnoses, assign a code from chapter 16 (Certain conditions originating in the perinatal period, P00-P96).
