ICD-10 Code H47.14 – Foster-Kennedy syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.14 – Foster-Kennedy syndrome
What it is
Foster-Kennedy syndrome is a neuro-ophthalmic pattern caused by a lesion compressing one optic nerve and raising intracranial pressure. It typically produces optic atrophy in one eye and papilledema in the other.
Clinical signs
Look for unilateral optic disc pallor or atrophy with contralateral optic disc swelling. Headache, visual loss, and other signs of an intracranial mass may also be present; clinical features vary, so refer to documentation.
When to use this code
Use H47.14 when the record specifically documents Foster-Kennedy syndrome or clearly describes the classic combination of optic atrophy in one eye and papilledema in the other due to an intracranial lesion. Code the syndrome when it is the confirmed diagnosis, not merely suspected findings.
Do not use for
Do not use this code for isolated optic atrophy, isolated papilledema, or visual loss without the syndrome documented. If the chart does not confirm the diagnosis, check documentation.
Coding tip
Confirm that both the syndrome and its underlying cause are documented, then code the intracranial condition separately when appropriate.
