ICD-10: H31.09

The ICD-10 code H31.09 refers to "Other chorioretinal scars," which is classified under the broader category of chorioretinal scars (H31.0). This code is used in clinical settings to document and bill for conditions involving scarring of the choroid and retina that do not fall into more specific categories.

Clinical Description

Definition

Chorioretinal scars are areas of fibrous tissue that develop in the choroid and retina, often as a result of previous inflammatory processes, trauma, or other pathological conditions. These scars can affect vision depending on their location and extent.

Etiology

The development of chorioretinal scars can be attributed to various factors, including:
- Infections: Conditions such as toxoplasmosis or cytomegalovirus can lead to scarring.
- Inflammatory Diseases: Uveitis or other inflammatory conditions can result in scar formation.
- Trauma: Physical injury to the eye can cause localized scarring.
- Vascular Issues: Retinal vascular occlusions may also lead to scarring.

Symptoms

Patients with chorioretinal scars may experience a range of symptoms, which can include:
- Blurred or distorted vision
- Scotomas (blind spots)
- Decreased visual acuity
- Changes in color perception

Diagnosis

Diagnosis typically involves a comprehensive eye examination, which may include:
- Fundoscopy: To visualize the retina and choroid.
