Dissem chorioretin inflammation of posterior pole, left eye

This code describes inflammation of both the choroid and retina, specifically affecting the posterior pole of the left eye, which has spread throughout the tissue. This condition involves widespread inflammatory changes in the light-sensitive tissue and the vascular layer beneath it, located at the back of the eye.

Apply this code when documentation indicates a diagnosis of disseminated chorioretinitis localized to the posterior pole of the left eye. This diagnosis is typically made by an ophthalmologist based on funduscopic examination and imaging studies showing diffuse inflammation.

• Ensure the documentation clearly specifies "disseminated" and "posterior pole" to differentiate from other forms of chorioretinitis.
• Verify laterality; this code is specific to the left eye. Use H30.111 for the right eye or H30.113 for bilateral involvement.
• Look for underlying causes or associated systemic conditions, as these may require additional coding.
