ICD-10 Code H53.412 – Scotoma involving central area, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.412 – Scotoma involving central area, left eye
What it is
This code identifies a scotoma, or blind spot, located in the central visual field of the left eye. It means the patient has a localized area of reduced or absent vision, not a complete loss of sight.
Clinical signs
Patients may report a dark spot, missing area, or blurred patch near the center of vision in the left eye. Clinical features vary; refer to documentation and exam findings such as visual field testing or ophthalmic assessment.
When to use this code
Use H53.412 when the provider documents a central scotoma affecting only the left eye. Code it for confirmed visual field loss in the central area when the diagnosis is specific to that eye. Check documentation if laterality or location is unclear.
Do not use for
Do not use this code for nonspecific visual disturbance, generalized vision loss, or scotoma involving another eye. If the record does not clearly identify a central left-eye scotoma, check documentation.
Coding tip
Verify both laterality and the central location before assigning this code.
