About Q70.0
Q70.0 is the ICD-10-CM diagnosis code for fused fingers. It belongs to category Q70 (syndactyly), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within Q70 (syndactyly), Q70.0 is specifically for fused fingers. Related codes cover Webbed fingers (Q70.1), fused toes (Q70.2), Webbed toes (Q70.3), Polysyndactyly, unspecified (Q70.4) and unspecified (Q70.9).
To report this condition, pick the subcode that matches the documentation: Q70.00 (unspecified hand), Q70.01 (right hand), Q70.02 (left hand) and Q70.03 (bilateral).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
