Polysyndactyly, unspecified

This code represents a congenital anomaly characterized by the presence of extra digits (polydactyly) fused together (syndactyly) in an unspecified location. It indicates a complex malformation involving both an excess number of digits and their abnormal webbing or fusion.

Use this code when documentation clearly indicates both polydactyly and syndactyly are present, but the specific digits or location (e.g., hand or foot) are not detailed. This code is appropriate for initial encounters where the full extent of the malformation is still being evaluated, or when the medical record lacks the specificity to assign a more precise code from the Q70.0-Q70.3 series.

• Avoid this code if the documentation specifies the affected digits or location (hand/foot); instead, code to the appropriate Q70.0-Q70.3 series.
• Ensure the medical record explicitly mentions both polydactyly and syndactyly; if only one is present, a different code is required.
• Query the provider for greater specificity regarding the affected digits or limb to allow for more precise coding, if possible.
