About Q70.2

Q70.2 is the ICD-10-CM diagnosis code for fused toes. 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), Q70.2 is specifically for fused toes. Related codes cover fused fingers (Q70.0), Webbed fingers (Q70.1), Webbed toes (Q70.3), Polysyndactyly, unspecified (Q70.4) and unspecified (Q70.9).

To report this condition, pick the subcode that matches the documentation: Q70.20 (unspecified foot), Q70.21 (right foot), Q70.22 (left foot) and Q70.23 (bilateral).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
