ICD-10 Code G93.2 – Benign intracranial hypertension (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G93.2 – Benign intracranial hypertension
What it is
Benign intracranial hypertension is increased pressure inside the skull without an identified mass lesion or hydrocephalus. It is also commonly called idiopathic intracranial hypertension.
Clinical signs
Typical findings include headache, papilledema, transient visual obscurations, pulsatile tinnitus, and sometimes diplopia from sixth nerve palsy. Clinical features vary; refer to documentation.
When to use this code
Use G93.2 when the provider documents benign intracranial hypertension or idiopathic intracranial hypertension. Code it for confirmed cases after evaluation for raised intracranial pressure, especially when the record notes papilledema or related neurologic findings.
Do not assign it for nonspecific headache alone. Verify that the diagnosis is established in the chart and not merely suspected or being ruled out.
Do not use for
Do not use this code for intracranial hypertension caused by a mass, hemorrhage, infection, or hydrocephalus. Check documentation if the condition is secondary or if the diagnosis is uncertain.
Coding tip
Confirm the exact provider wording, because “benign” and “idiopathic” intracranial hypertension are commonly used interchangeably in documentation.
