Benign neoplasm of eye and adnexa (D31) ICD-10-CM
The D31 code range covers benign neoplasm of eye and adnexa with 33 ICD-10-CM diagnosis codes. 24 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D31 range.
Benign Choroid Neoplasm
A neoplasm that arises from the choroid and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.
Benign Ciliary Body Neoplasm
A neoplasm that arises from the ciliary body and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.
Benign Conjunctival Neoplasm
A neoplasm that arises from the conjunctiva and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.
Benign Corneal Neoplasm
A neoplasm that arises from the cornea and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.
Benign Retinal Neoplasm
A neoplasm that arises from the retina and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.
About the D31 Code Range
Benign neoplasms are noncancerous growths. Here, they affect the eye or its surrounding structures.
The subdivisions first separate growths by site: the conjunctiva (D31.0), cornea (D31.1), retina (D31.2), choroid (D31.3), ciliary body (D31.4), or tear gland and duct (D31.5). D31.6 identifies an unspecified site in the orbit, or eye socket; D31.9 identifies an unspecified part of the eye. Each site then separates right, left and unspecified sides.
