ICD-10 Code H53.429 – Scotoma of blind spot area, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.429 – Scotoma of blind spot area, unspecified eye
What it is
This code identifies a scotoma, or blind spot, located in the optic disc blind spot area of an unspecified eye. Use it when the record documents the condition but does not specify which eye is affected.
Clinical signs
Patients may report a localized missing area in vision, often noticed as a spot they cannot see through. Clinical features vary; refer to documentation for the exact pattern and whether the finding was confirmed on exam or visual field testing.
When to use this code
Use H53.429 when the provider documents a scotoma involving the blind spot area and does not identify the right or left eye. It is appropriate for ophthalmology notes, visual field defects, or problem lists that clearly name this finding. If the chart gives a more specific eye later, code that instead.
Do not use for
Do not use this code for generalized vision loss, nonspecific blurred vision, or scotomas in another retinal location. Check documentation if the note describes the cause or a different type of visual field defect.
Coding tip
Confirm the eye laterality and the exact scotoma location before assigning H53.429.
