About D31.5

D31.5 is the ICD-10-CM diagnosis code for benign neoplasm of lacrimal gland and duct. It belongs to category D31 (benign neoplasm of eye and adnexa), 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 D31 (benign neoplasm of eye and adnexa), D31.5 is specifically for benign neoplasm of lacrimal gland and duct. Related codes cover conjunctiva (D31.0), cornea (D31.1), retina (D31.2), choroid (D31.3), ciliary body (D31.4), unspecified site of orbit (D31.6) and unspecified part of eye (D31.9).

To report this condition, pick the subcode that matches the documentation: D31.50 (duct), D31.51 (duct) and D31.52 (duct).

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