Webbed fingers, unspecified hand

This code describes a congenital anomaly where two or more fingers are abnormally joined together by a web of skin, without specifying which hand is affected. This condition, also known as syndactyly, can range from a partial webbing to a complete fusion of digits.

Use this code when the medical record clearly documents webbed fingers but does not specify whether the condition affects the right or left hand. This is appropriate for initial evaluations or when laterality is not yet determined or documented.

• Avoid using this code if laterality (right or left hand) is documented; instead, choose a more specific code from the Q70.1 series.
• Do not use this code for webbed toes; refer to codes in the Q70.3 series for syndactyly of toes.
• Query the provider if the documentation is unclear regarding laterality or if the webbed fingers are part of a larger syndrome.
