ICD-10 Code D31.22 – Benign neoplasm of left retina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.22 – Benign neoplasm of left retina
What it is
This code identifies a noncancerous tumor or growth in the left retina. It is used when documentation specifies a benign retinal neoplasm affecting the left eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an incidental retinal mass or lesion on eye exam, with or without visual symptoms, depending on size and location.
When to use this code
Use D31.22 when the provider documents a benign neoplasm of the left retina, such as a confirmed retinal tumor or benign retinal lesion in that eye. You should code it when laterality is clearly stated and the diagnosis is established, not merely suspected. If the record is unclear, check documentation.
Do not use for
Do not use this code for malignant retinal tumors or for lesions in the right eye or unspecified eye. Do not apply it to non-neoplastic retinal disorders, even if they are described as masses.
Coding tip
Verify laterality in the ophthalmology note before assigning D31.22.
