About Q72
Q72 is the ICD-10-CM diagnosis code for reduction defects of lower limb. It belongs to 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Q72.0 (limb), Q72.1 (present), Q72.2 (foot), Q72.3 (toe(s)), Q72.4 (femur), Q72.5 (tibia), Q72.6 (fibula), Q72.7 (foot) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
