D31.3 Benign neoplasm of choroid

Name of the Condition

• Benign Neoplasm of Choroid
  
  • Also known as a choroidal nevus or benign choroidal tumor.

Summary

A benign neoplasm of the choroid is a non-cancerous growth in the choroid, the vascular layer of the eye between the retina and sclera. These growths are typically harmless but may require monitoring to ensure they do not affect vision or transform into malignant tumors.

Causes

The exact cause of benign choroidal neoplasms is not well understood, but they are thought to arise from genetic factors or developmental anomalies in the eye's vascular layer.

Risk Factors

• Age: More common in middle-aged and elderly individuals.
• Genetic predisposition: Family history of ocular neoplasms.
• Ethnicity: Higher prevalence in Caucasian populations.

Symptoms

• Most individuals are asymptomatic and the neoplasm is discovered incidentally during an eye exam.
• Potential symptoms, if present, include blurred vision, visual field deficits, or floaters.

Diagnosis

Ophthalmic examination: Primary detection method via dilated eye exams. Imaging tests: Ultrasound, Optical Coherence Tomography (OCT), or fluorescein angiography to assess lesion characteristics and blood flow.

Treatment Options

• Observation: Most cases require regular monitoring for changes in size or symptoms.
• Intervention: Laser therapy or radiation may be considered if growth or complications occur.

Prognosis and Follow-Up

Prognosis is generally good with regular monitoring. Most benign neoplasms remain stable and do not affect vision. Follow-up typically involves periodic eye exams to detect any changes.

Complications

• Rarely, growth may lead to vision impairment or transformation into a malignant tumor.
• Potential complications include retinal detachment or choroidal neovascularization.

Lifestyle & Prevention

• Protect eyes from excessive sunlight with UV-blocking sunglasses.
• Maintain regular eye exams, especially if risk factors are present.

When to Seek Professional Help

• Seek care if experiencing new or worsening visual symptoms, such as blurred vision, floaters, or visual field changes.
• Prompt evaluation is recommended if the neoplasm is growing or causing discomfort.

Tips for Medical Coders

• Use code D31.3 for benign neoplasms of the choroid. Documentation should specify the location (e.g., right, left, or unspecified) and any associated symptoms or monitoring details. Ensure clinical notes support the diagnosis and any interventions performed.
