Retinal neovascularization, unspecified, bilateral

ICD10CM code

Name of the Condition

  • Retinal Neovascularization, Unspecified, Bilateral
  • Also referred to as bilateral retinal neovascularization.

Summary

  • Retinal neovascularization involves the formation of abnormal new blood vessels in the retina, occurring in both eyes. This can lead to vision complications if untreated.

Causes

  • This condition is frequently associated with retinal ischemia, often caused by diabetic retinopathy, retinal vein occlusion, or other conditions that affect retinal blood supply.

Risk Factors

  • Diabetes: Particularly uncontrolled diabetes leading to diabetic retinopathy.
  • Hypertension: High blood pressure can contribute to retinal vascular changes.
  • Age: Older individuals are at a higher risk due to age-related vascular changes.
  • Pre-existing eye conditions: Conditions like retinal vein occlusion elevate risk.

Symptoms

  • Visual disturbances: Such as floaters, blurred vision, or patches of vision loss.
  • Hemorrhages: May cause sudden significant visual impairment.
  • Typically, these symptoms affect both eyes.

Diagnosis

  • Ophthalmic Examination: Includes a dilated eye exam by an ophthalmologist.
  • Fluorescein Angiography: Helps visualize the retinal blood vessels to identify new growth.
  • Optical Coherence Tomography (OCT): Provides detailed images of the retina.

Treatment Options

  • Laser Therapy: Panretinal photocoagulation can reduce neovascularization.
  • Anti-VEGF Injections: Medications like ranibizumab or bevacizumab can limit blood vessel growth.
  • Vitrectomy: Surgery may be necessary if there is significant vitreous hemorrhage.

Prognosis and Follow-Up

  • With early treatment, the prognosis is generally good, although regular monitoring is essential to prevent complications.
  • Routine follow-ups with an ophthalmologist are crucial to assess treatment response and adjust plans if necessary.

Complications

  • Vision Loss: If untreated, can lead to severe or irreversible visual impairment.
  • Retinal Detachment: Due to the traction created by new vessels.
  • Vitreous Hemorrhage: Bleeding into the eye can obscure vision.

Lifestyle & Prevention

  • Diabetes Management: Maintain optimal blood glucose levels.
  • Blood Pressure Control: Necessary to reduce the impact on retinal vasculature.
  • Regular Eye Examinations: Essential for early detection and management.

When to Seek Professional Help

  • Sudden changes in vision, including flashes or floaters, require immediate ophthalmic attention.
  • Persistent or worsening vision problems should be promptly evaluated.

Tips for Medical Coders

  • Ensure bilateral nature is coded correctly; do not confuse with unilateral conditions.
  • Verify unspecified nature when coding; additional details might specify cause or associate condition which may alter coding.
