About Q71
Q71 is the ICD-10-CM diagnosis code for reduction defects of upper 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 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Q71.0 (limb), Q71.1 (present), Q71.2 (hand), Q71.3 (finger), Q71.4 (radius), Q71.5 (ulna), Q71.6 (hand), Q71.8 (limb) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
