I62.02 Nontraumatic subacute subdural hemorrhage

Name of the Condition

• Nontraumatic subacute subdural hemorrhage

Summary

Nontraumatic subacute subdural hemorrhage refers to bleeding between the dura mater and arachnoid membrane of the brain that occurs without external injury, with a subacute time course. This condition can lead to increased intracranial pressure and neurological impairment.

Causes

Causes may include hypertension (high blood pressure), cerebral amyloid angiopathy, anticoagulant or antiplatelet medication use, and blood-clotting disorders.

Risk Factors

• Increased risk is associated with older age, chronic alcohol use, hypertension, anticoagulant therapy, and conditions affecting blood clotting.

Symptoms

• Symptoms may include headache, confusion, drowsiness, weakness or numbness on one side of the body, difficulty speaking, and changes in consciousness.

Diagnosis

Diagnosing typically involves a neurological examination, followed by imaging tests such as a CT (Computed Tomography) scan or MRI (Magnetic Resonance Imaging) to identify the bleeding location and extent.

Treatment Options

• Treatment often involves stabilizing the patient and managing increased intracranial pressure. Options may include medication, observation, or surgical intervention to evacuate the hematoma.

Prognosis and Follow-Up

Prognosis depends on the size of the hemorrhage, patient age, and overall health.

Complications

• Potential complications include increased intracranial pressure, neurological deficits, seizures, and in severe cases, coma or death.

Lifestyle & Prevention

• Managing risk factors such as hypertension and avoiding excessive alcohol use may help reduce the risk of this condition.

When to Seek Professional Help

• Seek immediate medical attention if experiencing sudden severe headache, confusion, weakness, or changes in consciousness.

Tips for Medical Coders

• Use this code for nontraumatic subacute subdural hemorrhage. Ensure documentation supports the subacute time frame and absence of trauma. Verify that the diagnosis aligns with clinical findings and imaging results.
