ICD-10: H34.239

Retinal artery branch occlusion (RABO) is a significant ocular condition characterized by the obstruction of blood flow in one of the branches of the retinal artery. The ICD-10 code H34.239 specifically refers to this condition when it occurs in an unspecified eye, indicating that the exact eye affected is not specified in the medical documentation.

Clinical Description

Definition

Retinal artery branch occlusion occurs when a branch of the retinal artery becomes blocked, typically due to a thrombus (blood clot) or embolus (a particle that travels through the bloodstream). This blockage can lead to ischemia (lack of blood supply) in the affected area of the retina, resulting in potential vision loss.

Symptoms

Patients with retinal artery branch occlusion may experience a range of symptoms, including:
- Sudden, painless vision loss in part of the visual field.
- Visual disturbances, such as blurred vision or scotomas (blind spots).
- In some cases, patients may not notice any symptoms until a comprehensive eye examination is performed.

Risk Factors

Several risk factors are associated with retinal artery branch occlusion, including:
- Age: The condition is more common in older adults.
- Cardiovascular diseases: Conditions such as hypertension, diabetes, and hyperlipidemia increase the risk.
- Smoking: Tobacco use is a significant risk factor for vascular occlusions.
- Other systemic conditions: Disorders like atrial fibrillation can contribute to the formation of emboli.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a comprehensive eye examination, including:
- Visual acuity tests: To assess the extent of vision loss.
- Fundoscopy: To visualize the retina and identify signs of occlusion, such as retinal edema or cotton wool spots.
- Fluorescein angiography: This imaging technique helps to visualize blood flow in the retina and confirm the diagnosis.

ICD-10 Classification

The ICD-10-CM code H34.239 is categorized under "Retinal vascular occlusions," specifically indicating a branch occlusion without specifying which eye is affected. This classification is crucial for billing and coding purposes in healthcare settings, ensuring accurate documentation and reimbursement for services rendered.

Treatment Options

Management Strategies

Treatment for retinal artery branch occlusion focuses on addressing the underlying causes and managing symptoms. Options may include:
