ICD-10 Code G06.2 – Extradural and subdural abscess, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G06.2 – Extradural and subdural abscess, unspecified
What it is
G06.2 identifies an abscess located in the extradural or subdural space, but the record does not specify which space is involved. Use it when documentation confirms an intracranial or intraspinal abscess and no more precise site is stated.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include localized pain, neurologic deficits, fever, headache, or signs of compression, depending on whether the abscess is cranial or spinal.
When to use this code
Use this code when the provider documents an extradural or subdural abscess without naming the exact compartment. It also fits cases where imaging or operative notes confirm an abscess, but the chart does not distinguish extradural from subdural involvement. If the site is specified, code the documented location instead.
Do not use for
Do not use G06.2 for epidural hematoma, meningitis, or abscesses in other body sites. Check documentation if the note describes a different intracranial or spinal infection.
Coding tip
Query for the exact space involved when the note says only “abscess,” because a more specific code may be available.
