2025 ICD-10-CM code G00.1
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Infectious Diseases - Inflammatory diseases of the central nervous system (G00-G09) Diseases of the nervous system (G00-G99) Feed
Pneumococcal meningitis is an inflammation of the brain and spinal cord membranes caused by Streptococcus pneumoniae bacteria.
No specific modifier rules are associated directly with G00.1. However, modifiers might be applicable depending on the specific circumstances of the encounter and the services provided (e.g., place of service modifiers).
Medical necessity for treatment of pneumococcal meningitis is established by the presence of clinical symptoms and signs consistent with the diagnosis, confirmed by laboratory findings (positive bacterial culture from CSF).Treatment is medically necessary due to the potential for severe morbidity and mortality if left untreated.Prompt initiation of appropriate antibiotics is critical for reducing the risk of permanent neurological damage and death.
Diagnosis and treatment of pneumococcal meningitis involves a range of responsibilities including taking patient history, conducting physical examination, ordering and interpreting laboratory tests (blood cultures, CSF analysis), performing imaging studies (CT, MRI), administering intravenous antibiotics and steroids, and managing potential complications such as seizures, shock, and respiratory failure.Ongoing monitoring and follow-up care are also essential.

In simple words: Pneumococcal meningitis is a serious infection of the membranes covering the brain and spinal cord, caused by bacteria. It causes symptoms like high fever, headache, and stiff neck.It's treated with strong antibiotics in the hospital.
Pneumococcal meningitis, a severe bacterial infection, is characterized by inflammation of the meninges (protective membranes surrounding the brain and spinal cord) caused by Streptococcus pneumoniae bacteria.The infection can spread through droplet infection or direct contact, entering the bloodstream and affecting the cerebrospinal fluid. Symptoms include high fever, headache, neck stiffness, light sensitivity, vomiting, and potentially chest pain.Severe cases can lead to seizures, coma, brain damage, deafness, or death. Diagnosis involves physical examination, blood and cerebrospinal fluid cultures, and imaging studies (CT, MRI, X-rays). Treatment typically requires hospitalization with intravenous antibiotics (e.g., ceftriaxone, vancomycin, ampicillin) and steroids to reduce inflammation and intracranial pressure.
Example 1: A 2-year-old child presents with fever, headache, and irritability.Lumbar puncture reveals purulent cerebrospinal fluid, and bacterial culture identifies Streptococcus pneumoniae. The physician diagnoses pneumococcal meningitis and initiates treatment with intravenous ceftriaxone and vancomycin. The patient is admitted to the hospital for close monitoring., A 65-year-old immunocompromised patient develops pneumococcal meningitis following a recent respiratory infection. The patient presents with altered mental status, nuchal rigidity, and fever.A CT scan shows signs of cerebral edema. Treatment with intravenous antibiotics and corticosteroids is started immediately, with close monitoring for complications like increased intracranial pressure., A young adult presents with sudden onset of severe headache, fever, and photophobia.Initial examination shows meningeal signs. Diagnostic workup confirms pneumococcal meningitis, and treatment includes intravenous antibiotics, supportive care, and monitoring for complications.Prophylactic antibiotic treatment is offered to close contacts.
Detailed patient history including symptoms, onset, any recent infections, and relevant medical history. Results of physical examination, including neurological assessment. Laboratory results: complete blood count, blood cultures, cerebrospinal fluid analysis (Gram stain, culture, cell count, protein and glucose levels). Imaging studies as needed (CT scan, MRI). Documentation of treatment plan, response to treatment, and any complications encountered.
** This code should be used to capture the diagnosis of pneumococcal meningitis.Appropriate selection of additional codes may be necessary to reflect any complications or comorbidities.
