Blastomycotic meningoencephalitis
ICD-10 B40.81 is a billable code used to indicate a diagnosis of blastomycotic meningoencephalitis.
Blastomycotic meningoencephalitis is a severe fungal infection caused by the organism Blastomyces dermatitidis, which primarily affects the lungs but can disseminate to the central nervous system (CNS). This condition is characterized by inflammation of the meninges and brain tissue, leading to symptoms such as fever, headache, neck stiffness, altered mental status, and neurological deficits. The infection is more common in immunocompromised individuals, including those with HIV/AIDS, cancer, or those on immunosuppressive therapy. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests, including cultures and serological tests to identify the presence of the fungus. Treatment usually involves antifungal medications such as itraconazole or amphotericin B, depending on the severity of the infection and the patient's immune status. Early recognition and treatment are crucial to improve outcomes and reduce the risk of complications.
Detailed clinical history, laboratory results, and treatment plans.
Patients presenting with fever, neurological symptoms, and a history of exposure to endemic areas.
Documentation must clearly indicate the diagnosis and any underlying immunocompromising conditions.
Neurological examination findings, imaging results, and treatment response.
Patients with altered mental status and neurological deficits requiring differential diagnosis.
Ensure that neurological assessments are documented to support the diagnosis of meningoencephalitis.
When a fungal culture is performed to confirm the diagnosis of blastomycosis.
Document the source of the culture and the clinical indication.
Infectious disease specialists should ensure that the culture results are clearly linked to the diagnosis.
Common symptoms include fever, headache, neck stiffness, altered mental status, and neurological deficits. Patients may also present with respiratory symptoms if there is pulmonary involvement.
