    ICD-10-CM Code For Tuberculosis Of Nervous System: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A17 includes tuberculosis infections of the central nervous system such as tuberculous meningitis, intracranial tuberculoma, and spinal cord tuberculosis that cause neurological dysfunction. These ICD-10-CM diagnosis codes are used to document central nervous system involvement by Mycobacterium tuberculosis, capturing disease severity, anatomic site, and clinical complexity relevant to neurological compromise. Accurate coding within the ICD-10-CM A17 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM A17: Tuberculosis Of Nervous System Overview

    The ICD-10-CM A17 group represents tuberculosis infections that primarily affect the central nervous system, including tuberculous meningitis and intracranial tuberculomas. These diagnoses target the brain, meninges, and spinal cord structures and reflect severe extrapulmonary tuberculosis. Accurate coding matters for reimbursement because it captures disease severity and organ involvement that influence clinical resource use and claim adjudication.

    When to Use

    Use a code from this group when clinical documentation confirms tuberculosis affecting the brain, meninges, or spinal cord, such as tuberculous meningitis or confirmed intracranial tuberculoma. Select the code that specifies the precise site and any noted complications to accurately represent severity and guide coding for reimbursement and care tracking.

    Typical Clinical Scenarios

    • A young adult presents to the emergency department with acute onset severe headache, high fever, neck stiffness, photophobia, and altered mental status. Cerebrospinal fluid analysis shows lymphocytic pleocytosis and acid-fast bacilli are identified on smear or PCR confirms Mycobacterium tuberculosis in CSF, consistent with tuberculous meningitis; urgent anti-tuberculosis therapy is initiated and neurologic monitoring arranged. Typical codes: A17.0, A17.1
    • An immunocompromised middle-aged patient with known pulmonary tuberculosis develops progressive focal neurologic deficits over weeks, including unilateral weakness and seizures; brain MRI demonstrates a ring-enhancing intracranial abscess(es) with features suggestive of tuberculoma. Neurosurgical consultation and prolonged antitubercular therapy are indicated, and a nervous system tuberculous lesion diagnosis is assigned. Typical codes: A17.81, A17.82
    • A patient with a history of treated spinal tuberculosis years earlier now presents with chronic back pain, progressive lower extremity weakness, sensory changes, and signs of spinal cord compression; imaging shows calcified intradural granulomas and adhesive arachnoiditis related to prior tuberculous involvement of the spine. This represents a chronic complication of nervous system tuberculosis requiring rehabilitation and possible surgical evaluation, and a sequela code from this group is used. Typical codes: A17.83, A17.89, A17.9
