ICD-10: G96.1

ICD-10 code G96.1 refers to "Disorders of meninges, not elsewhere classified." This code is part of the broader category of neurological disorders and specifically addresses conditions affecting the meninges, which are the protective membranes covering the brain and spinal cord.

Clinical Description

Definition

Disorders of the meninges encompass a variety of conditions that can lead to inflammation, infection, or other pathological changes in these membranes. The meninges consist of three layers: the dura mater, arachnoid mater, and pia mater. Conditions classified under G96.1 are those that do not fit into more specific categories within the ICD-10 coding system.

Common Conditions

While G96.1 is a general code, it may include several specific disorders, such as:

• Meningitis: Inflammation of the meninges, which can be caused by viral, bacterial, or fungal infections.
• Meningeal carcinomatosis: Involvement of the meninges by cancer cells, often seen in advanced stages of cancer.
• Meningeal fibrosis: Scarring of the meninges, which can occur after infections or surgeries.
• Meningeal hemorrhage: Bleeding in the meninges, which can result from trauma or vascular malformations.

Symptoms

Symptoms associated with disorders of the meninges can vary widely depending on the underlying cause but may include:

• Severe headache
• Stiff neck
• Sensitivity to light (photophobia)
• Nausea and vomiting
• Altered mental status or confusion
• Seizures

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and diagnostic imaging. Common methods include:

• Lumbar puncture (spinal tap): To analyze cerebrospinal fluid (CSF) for signs of infection or other abnormalities.
• Magnetic Resonance Imaging (MRI): To visualize the meninges and detect any structural changes or lesions.
• Computed Tomography (CT) scan: To assess for bleeding or other acute changes in the brain.
