ICD-10 Code G06 – Intracranial and intraspinal abscess and granuloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G06 – Intracranial and intraspinal abscess and granuloma
What it is
G06 identifies a localized collection of pus or granulomatous inflammation inside the skull or spinal canal. Use it when the record documents an intracranial or intraspinal abscess or granuloma.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include neurologic deficits, headache, fever, back pain, or signs of raised intracranial pressure, depending on the site involved.
When to use this code
Use G06 when the provider clearly diagnoses an abscess or granuloma involving the brain, meninges, or spinal canal. You should code from the documented anatomic location and clinical impression, not from imaging suspicion alone. If the note is unclear, check documentation.
Do not use for
Do not use this code for superficial soft-tissue abscesses, epidural abscesses outside the intracranial or intraspinal spaces, or nonspecific infection without a documented abscess or granuloma. Check documentation for the exact site.
Coding tip
Confirm whether the lesion is intracranial or intraspinal before assigning G06, and code the most specific documented site available.
