Benign neoplasm of unspecified part of left eye

This diagnosis code signifies the presence of a non-malignant tumor originating in an unspecified location within the left eye. It indicates a benign growth that does not invade surrounding tissues or metastasize. The specific anatomical site of the neoplasm within the left eye is not documented or is unknown.

This code is appropriate when documentation confirms a benign neoplasm of the left eye, but the precise intraocular location (e.g., conjunctiva, cornea, retina, choroid) is not specified by the clinician. It is used when the physician's notes indicate "benign neoplasm of left eye, site unspecified" or similar phrasing.

• Avoid using this code if a more specific anatomical site within the left eye is documented (e.g., D31.02 for conjunctiva, D31.22 for retina).
• Ensure the laterality (left eye) is clearly documented. If the laterality is unspecified, use D31.90.
• Confirm the neoplasm is explicitly stated as "benign"; otherwise, consider codes for uncertain behavior or malignant neoplasms.
