ICD-10 Code G52.7 – Disorders of multiple cranial nerves (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G52.7 – Disorders of multiple cranial nerves
What it is
G52.7 identifies a disorder affecting more than one cranial nerve. Use it when documentation shows multiple cranial nerve involvement, but the record does not support a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include combined deficits such as facial weakness, swallowing difficulty, diplopia, or altered sensation in cranial nerve distributions.
When to use this code
Use G52.7 when the provider documents multiple cranial nerve dysfunction, palsy, or neuropathy without naming a more specific cause. It can fit cases where the affected nerves are listed, but the final diagnosis remains nonspecific.
Apply the code only when the chart clearly supports involvement of several cranial nerves. If the record identifies an underlying disease, lesion, or more specific cranial nerve disorder, code that condition instead.
Do not use for
Do not use this code for a single cranial nerve disorder or for a clearly defined underlying neurologic disease. Check documentation if the provider states a specific etiology or a different nerve category.
Coding tip
Look for explicit wording such as “multiple cranial nerve palsies” before assigning G52.7.
