About coding brain abscess
The ICD-10-CM code for brain abscess is G06.0 (Intracranial abscess and granuloma). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G06.0.
Within G06 (intracranial and intraspinal abscess and granuloma), G06.0 is specifically for intracranial abscess and granuloma. Related codes cover intraspinal abscess and granuloma (G06.1) and extradural and subdural abscess, unspecified (G06.2).
Don't report G06.0 together with the conditions in its Excludes1 note: tuberculous intracranial abscess and granuloma (A17.81).
Use an additional code (B95-B97) to identify infectious agent.
