Intracranial and intraspinal abscess and granuloma (G06)

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.

Instructional Notations

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.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.
