ICD-10 Code D31.01 – Benign neoplasm of right conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.01 – Benign neoplasm of right conjunctiva
What it is
This code identifies a noncancerous growth on the right conjunctiva, the thin membrane covering the white of the eye and inner eyelids. It indicates a benign lesion documented on the right side.
Clinical signs
Clinical features vary; refer to documentation. A conjunctival benign neoplasm may appear as a visible, localized mass or pigmented lesion, sometimes found during routine eye examination or after irritation prompts evaluation.
When to use this code
Use D31.01 when the provider documents a benign neoplasm of the right conjunctiva. This applies whether the lesion is newly identified or followed over time, as long as the diagnosis is confirmed in the record.
Code it from ophthalmology notes, pathology reports, or assessment statements that clearly specify the right conjunctiva. If the documentation only says “conjunctival lesion” or is unclear about laterality, check documentation.
Do not use for
Do not use this code for malignant conjunctival tumors, uncertain masses, or lesions on the left conjunctiva. If the chart does not confirm benign behavior or right-sided location, choose a different code or verify the record.
Coding tip
Always confirm both laterality and benign nature before assigning D31.01.
