Intracranial and intraspinal abscess and granuloma (G06) ICD-10-CM
The G06 code range covers intracranial and intraspinal abscess and granuloma with 4 ICD-10-CM diagnosis codes. 3 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Epidural Abscess
Circumscribed collections of suppurative material occurring in the spinal or intracranial EPIDURAL SPACE. The majority of epidural abscesses occur in the spinal canal and are associated with OSTEOMYELITIS of a vertebral body; ANALGESIA, EPIDURAL; and other conditions. Clinical manifestations include local and radicular pain, weakness, sensory loss, URINARY INCONTINENCE, and FECAL INCONTINENCE. Cranial epidural abscesses are usually associated with OSTEOMYELITIS of a cranial bone, SINUSITIS, or OTITIS MEDIA.

About the G06 Code Range
The ICD-10 codes G06, G06.0, G06.1, and G06.2 categorize infections presenting as abscesses or granulomas within the brain (intracranial) or spinal areas (intraspinal). These codes are essential for identifying and documenting specific types of central nervous system (CNS) abscesses and related granulomatous infections.
The broad code G06 covers all intracranial and intraspinal abscesses and granulomas. G06.0 refers explicitly to intracranial conditions such as cerebral abscesses, epidural or subdural intracranial abscesses, and granulomas affecting brain areas like the cerebellum or pituitary region, encompassing terms like late effects of pyogenic brain abscess or fungal brain infections. The ICD-10 code for intraspinal abscess and granuloma (G06.1) is used for abscesses or granulomas within the spinal cord or its surrounding spaces, including fungal or mycobacterial infections identified by synonyms like spinal epidural abscess or intraspinal granuloma. Finally, G06.2 designates extradural and subdural abscesses where the exact location is unspecified, often called epidural or subdural abscesses. These codes help healthcare professionals accurately classify severe CNS infections for treatment and reporting purposes.
