    ICD-10-CM Code For Meningitis In Bacterial Diseases Classified Elsewhere: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group G01 includes meningitis that occurs as a complication or manifestation of bacterial diseases classified in other chapters, such as bacterial infections of specific organs or systemic bacterial infections with central nervous system involvement. These ICD-10-CM diagnosis codes are used to document cases where bacterial pathogens cause inflammation of the meninges, capturing information about disease association, organ involvement, and clinical complexity relevant to central nervous system infection. Accurate coding within the ICD-10-CM G01 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM G01: Meningitis In Bacterial Diseases Classified Elsewhere Overview

    This group represents meningitis that occurs as a manifestation of bacterial infections classified in other chapters rather than primary central nervous system infections. It targets inflammatory infections of the meninges caused by bacteria identified elsewhere in the International Classification of Diseases, 10th Revision, Clinical Modification. Accurate coding matters because it links the central nervous system manifestation to the underlying bacterial disease and supports appropriate claim adjudication and clinical documentation.

    When to Use

    Use a code from this group when a patient has meningitis documented as caused by a specific bacterial disease that is indexed to another chapter of the International Classification of Diseases, 10th Revision, Clinical Modification. Assign these codes to capture the meningitis manifestation along with the underlying bacterial diagnosis to reflect clinical complexity and support accurate billing.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset high fever, severe headache, neck stiffness, photophobia, and altered mental status after recent sinusitis; cerebrospinal fluid analysis shows neutrophilic pleocytosis and positive bacterial culture consistent with spread from a nearby focus. Because the central nervous system inflammation is due to a bacterial infection originating outside the CNS, a diagnosis from this group is assigned to capture meningitis caused by another bacterial disease. Typical codes: G01
    • A hospitalized patient with known bacterial otitis media develops persistent fever, worsening headache, and focal neurologic deficits; imaging and lumbar puncture confirm meningitis attributed to contiguous spread of the middle ear infection. The diagnosis from this group is used to indicate meningitis resulting from a bacterial disease located elsewhere (otogenic source) complicating the primary infection. Typical codes: G01
    • A patient in the intensive care unit with bloodstream infection from Staphylococcus aureus develops acute encephalopathy and signs of meningeal irritation; CSF findings and positive blood cultures support bacterial meningitis secondary to hematogenous dissemination. A code from this group is recorded to denote meningitis caused by a bacterial disease originating outside the central nervous system. Typical codes: G01
