ICD-10 Code G06.0 – Intracranial abscess and granuloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G06.0 – Intracranial abscess and granuloma
What it is
G06.0 identifies a localized collection of pus or inflammatory granuloma inside the skull. Use it when documentation shows an intracranial abscess or granulomatous lesion, and the site is not otherwise specified.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include headache, fever, neurologic deficits, seizures, or signs of raised intracranial pressure, but the diagnosis should be supported by imaging or specialist evaluation.
When to use this code
Use G06.0 when the provider documents an intracranial abscess, brain abscess, or intracranial granuloma without a more specific code. It also fits cases described as a suspected or confirmed localized intracranial infectious mass when documentation supports the diagnosis.
If the record identifies a specific anatomic site or a different intracranial infection, code that condition instead. Check documentation when the note uses vague terms such as mass, lesion, or collection.
Do not use for
Do not use this code for epidural, subdural, or spinal abscesses, or for meningitis. If the documentation points to another intracranial disorder, choose the more specific diagnosis.
Coding tip
Look for provider wording that clearly states abscess or granuloma inside the skull before assigning G06.0.
