D23.12Other benign neoplasm of skin of left eyelid, including canthus

D23.12 is the ICD-10-CM diagnosis code for other benign neoplasm of skin of left eyelid, including canthus. It belongs to category D23 (other benign neoplasms of skin), 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 D23.1 (other benign neoplasm of skin of eyelid, including canthus), D23.12 is specifically for other benign neoplasm of skin of left eyelid, including canthus. Related codes cover unspecified eyelid, including canthus (D23.10) and right eyelid, including canthus (D23.11).

To report this condition, pick the subcode that matches the documentation: D23.121 (canthus) and D23.122 (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).
