About coding eye nevus

The ICD-10-CM code for eye nevus is D31.9 (Benign neoplasm of unspecified part of eye).

Within D31, choose D31.9 (unspecified part of eye) only when documentation doesn't support a more specific option: conjunctiva (D31.0), cornea (D31.1), retina (D31.2), choroid (D31.3), ciliary body (D31.4), lacrimal gland and duct (D31.5) and unspecified site of orbit (D31.6).

To report this condition, pick the subcode that matches the documentation: D31.90 (eye), D31.91 (eye) and D31.92 (eye).

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