About Q82

Q82 is the ICD-10-CM diagnosis code for other congenital malformations of skin. It belongs to block Q80-Q89 (other congenital malformations) 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: Q82.0 (lymphedema), Q82.1 (pigmentosum), Q82.2 (mastocytosis), Q82.3 (pigmenti), Q82.4 ((anhidrotic)), Q82.5 (nevus), Q82.6 (dimple), Q82.8 (skin) and 1 more.

Don't report Q82 together with the conditions in its Excludes1 note: acrodermatitis enteropathica (E83.2), congenital erythropoietic porphyria (E80.0), pilonidal cyst or sinus (L05.-) and Sturge-Weber (-Dimitri) syndrome (Q85.89).

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