About D22.12

D22.12 is the ICD-10-CM diagnosis code for Melanocytic nevi of left eyelid, including canthus. 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 2 subcodes must be used instead.

Within D22.1 (Melanocytic nevi of eyelid, including canthus), D22.12 is specifically for Melanocytic nevi of left eyelid, including canthus. Related codes cover unspecified eyelid, including canthus (D22.10) and right eyelid, including canthus (D22.11).

To report this condition, pick the subcode that matches the documentation: D22.121 (canthus) and D22.122 (canthus).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 216.1 (benign neoplasm of eyelid, including canthus).
