ICD-10 Code H53.461 – Homonymous bilateral field defects, right side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.461 – Homonymous bilateral field defects, right side
What it is
This code identifies a loss of the same side of the visual field in both eyes on the right. It usually reflects a lesion behind the optic chiasm, affecting visual pathways.
Clinical signs
Patients may report missing objects on the right side, bumping into items, or difficulty reading. Examination typically shows a congruent right-sided homonymous field defect; clinical features vary, refer to documentation.
When to use this code
Use H53.461 when the record clearly documents a right homonymous visual field defect, whether found on confrontation testing, formal perimetry, or specialist assessment. Code it for confirmed bilateral field loss affecting the right side, not for vague blurred vision or general eye complaints.
Do not use for
Do not use this code for monocular vision loss, nonspecific visual disturbance, or left-sided homonymous defects. Check documentation if the note only states “visual field loss” without laterality.
Coding tip
Capture the laterality exactly as documented, because the right-side designation changes the code selection.
