H44.2A3 Degenerative myopia with choroidal neovascularization, bilateral eye

Name of the Condition

• Degenerative Myopia with Choroidal Neovascularization, Bilateral Eye
• Also known as pathologic myopia with CNV, bilateral eye.

Summary

Degenerative myopia with choroidal neovascularization is a condition where excessive eyeball elongation leads to progressive vision loss, compounded by abnormal blood vessel growth (neovascularization) in the choroid. This can cause severe vision impairment due to retinal and macular damage, affecting both eyes.

Causes

The exact cause is not fully understood but involves genetic predisposition and structural changes in the eye. Choroidal neovascularization may arise from retinal stress or degeneration associated with myopia progression.

Risk Factors

• High degree of nearsightedness from an early age.
• Family history of degenerative myopia.
• Advanced age or prolonged myopia progression.

Symptoms

• Sudden or gradual vision loss in both eyes.
• Distorted or blurred central vision in both eyes.
• Visual field defects in both eyes.
• Increased floaters or flashes of light in both eyes.

Diagnosis

Diagnosis involves a comprehensive eye exam, including visual acuity testing, retinal imaging (e.g., OCT), and fluorescein angiography to detect neovascularization. Refractive error measurement and fundus examination are also performed, with focus on both eyes.

Treatment Options

• Anti-VEGF injections to inhibit abnormal blood vessel growth.
• Photodynamic therapy for selected cases.
• Low-vision aids or prescri

Prognosis and Follow-Up

Prognosis depends on the extent of retinal damage and response to treatment. Regular follow-up with an ophthalmologist is essential to monitor disease progression and adjust therapy as needed.

Complications

• Permanent vision loss.
• Retinal detachment.
• Macular scarring.

Lifestyle & Prevention

• Maintain regular eye exams, especially if high myopia is present.
• Protect eyes from excessive strain or injury.
• Follow prescribed treatments to slow progression.

When to Seek Professional Help

Seek immediate care if experiencing sudden vision changes, severe eye pain, or new floaters, as these may indicate worsening neovascularization or other complications.

Tips for Medical Coders

Document the bilateral involvement clearly in the medical record. Ensure the diagnosis supports the use of H44.2A3, and note any associated findings (e.g., visual acuity, imaging results) to justify coding specificity.
