D22.2Melanocytic nevi of ear and external auricular canal

D22.2 is the ICD-10-CM diagnosis code for Melanocytic nevi of ear and external auricular canal. It belongs to category D22 (Melanocytic nevi), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within D22 (Melanocytic nevi), D22.2 is specifically for Melanocytic nevi of ear and external auricular canal. Related codes cover of lip (D22.0), of eyelid, including canthus (D22.1), of other and unspecified parts of face (D22.3), of scalp and neck (D22.4), of trunk (D22.5), of upper limb, including shoulder (D22.6), of lower limb, including hip (D22.7) and unspecified (D22.9).

To report this condition, pick the subcode that matches the documentation: D22.20 (canal), D22.21 (canal) and D22.22 (canal).

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