Fused fingers, unspecified hand

This code describes congenital syndactyly, a condition where two or more fingers are abnormally joined together. The fusion can involve skin, soft tissue, or bone, and the specific hand affected is not documented or is unknown.

This code is appropriate for cases of syndactyly when the medical record does not specify whether the right or left hand is affected. It should be used when documentation clearly indicates fused fingers but lacks laterality.

• Avoid using this code if laterality (right or left hand) is documented; instead, use a more specific code from the Q70.0 series.
• Query the provider for clarification on laterality if it's missing from the documentation to allow for more specific coding.
• Do not confuse with acquired fusion of fingers, which would be coded differently (e.g., due to trauma or burn contracture).
