Posterior cerebral artery syndrome
ICD-10 G46.2 is a billable code used to indicate a diagnosis of posterior cerebral artery syndrome.
Posterior cerebral artery syndrome (PCAS) refers to a collection of neurological deficits resulting from ischemia or infarction in the territories supplied by the posterior cerebral artery (PCA). This syndrome can manifest as a result of transient ischemic attacks (TIAs) or strokes affecting the PCA, leading to symptoms such as visual field deficits, sensory disturbances, and cognitive impairments. Patients may experience homonymous hemianopsia, which is a loss of half of the visual field on the same side in both eyes, and may also present with memory deficits due to involvement of the temporal lobe. The PCA supplies critical areas of the brain, including the occipital lobe, which is responsible for visual processing, and parts of the thalamus, which relay sensory information. Stroke prevention strategies are crucial for patients at risk of PCA syndrome, emphasizing the management of risk factors such as hypertension, diabetes, and hyperlipidemia. Early recognition and intervention can significantly improve outcomes and reduce the risk of recurrent strokes. Understanding the clinical presentation and implications of PCA syndrome is essential for effective management and coding.
Detailed neurological examination findings, imaging results, and treatment plans.
Patients presenting with visual disturbances, memory issues, or sensory deficits.
Ensure comprehensive documentation of all neurological assessments and risk factors.
Documentation of risk factor management, patient history, and referrals to specialists.
Patients with risk factors for stroke presenting with TIAs or minor neurological symptoms.
Focus on preventive care and management of comorbid conditions.
Used to evaluate for acute ischemic stroke or hemorrhage.
Indication for the scan and findings must be documented.
Neurology practices should ensure imaging correlates with clinical findings.
Common symptoms include visual field deficits, sensory disturbances, and cognitive impairments, particularly memory issues.
PCA syndrome typically presents with visual disturbances and memory deficits, while other syndromes may have different symptom profiles, such as motor deficits in MCA syndrome.
