About D31.2

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

To report this condition, pick the subcode that matches the documentation: D31.20 (retina), D31.21 (retina) and D31.22 (retina).

Don't report D31.2 together with the conditions in its Excludes1 note: dark area on retina (D49.81), hemangioma of retina (D49.81), neoplasm of unspecified behavior of retina and choroid (D49.81) and retinal freckle (D49.81).

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