ICD-10 Code H47.141 – Foster-Kennedy syndrome, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.141 – Foster-Kennedy syndrome, right eye
What it is
H47.141 identifies Foster-Kennedy syndrome affecting the right eye. It refers to optic nerve findings linked to an intracranial mass, with compression on one side and optic atrophy on the other.
Clinical signs
Typical findings include unilateral optic atrophy and papilledema in the opposite eye, often with visual loss or headache. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Foster-Kennedy syndrome specifically involving the right eye. It may apply when the right optic nerve is described as atrophic or compressed in the setting of a confirmed intracranial lesion. Check documentation if laterality is unclear.
Do not use for
Do not use this code for isolated optic atrophy, papilledema, or nonspecific visual disturbance without documented Foster-Kennedy syndrome. Do not assign it if the right-eye laterality is not supported.
Coding tip
Confirm both the syndrome name and laterality in the record before coding H47.141.
