H31.003 Unspecified chorioretinal scars, bilateral

Name of the Condition

• Unspecified Chorioretinal Scars, Bilateral (ICD Code: H31.003)

Summary

Unspecified chorioretinal scars, bilateral, are permanent changes in the retina and choroid of both eyes resulting from prior injury, inflammation, or infection. These scars represent a healed state of previous ocular pathology and may affect visual function depending on their location and size in each eye.

Causes

Unspecified chorioretinal scars typically develop as a result of resolved inflammatory, infectious, or traumatic events affecting both eyes. Common underlying causes include past episodes of uveitis, retinal infections (such as toxoplasmosis), or trauma that has since healed.

Risk Factors

• History of ocular inflammation or infection in both eyes
• Prior eye trauma to both eyes
• Systemic conditions predisposing to retinal damage (e.g., autoimmune diseases)

Symptoms

• Asymptomatic if the scars do not affect the macula
• Blurred or distorted vision if the scars involve the central retina
• Reduced visual acuity in severe cases

Diagnosis

Diagnosis is confirmed through a comprehensive eye examination, including dilated fundus evaluation to visualize the scars. Optical coherence tomography (OCT) or fundus photography may be used to document the scars' location and impact on retinal structure.

Treatment Options

Treatment is generally not required for chorioretinal scars themselves, as they represent healed tissue.

Prognosis and Follow-Up

The prognosis depends on the location and size of the scars. Regular follow-up with an eye care professional is recommended to monitor for any changes in vision or new ocular pathology.

Complications

• Permanent vision loss if scars involve the macula
• Increased risk of future retinal issues in affected areas

Lifestyle & Prevention

• Protect eyes from injury
• Manage systemic conditions that may affect eye health
• Follow up with an eye care professional for regular examinations

When to Seek Professional Help

Seek immediate medical attention if you experience sudden vision changes, eye pain, or new floaters, as these may indicate a new ocular issue.

Tips for Medical Coders

Document the bilateral nature of the chorioretinal scars and any associated visual symptoms or underlying conditions. Ensure the code H31.003 is used when the scars are unspecified and affect both eyes.
