Unsp disseminated chorioretinal inflammation, left eye

This diagnosis code signifies a widespread inflammatory process affecting both the choroid and retina in the left eye, where the specific cause or type of inflammation has not been identified. It indicates a diffuse chorioretinitis without further specification of its etiology.

Use this code when documentation confirms a disseminated chorioretinal inflammation in the left eye, but the ophthalmologist has not yet determined the specific type or cause of the inflammation. This is often an initial diagnosis while further diagnostic workup is pending.

• Ensure the documentation explicitly states "left eye" and "unspecified" or "diffuse" chorioretinal inflammation.
• Avoid using this code if a more specific type of chorioretinal inflammation (e.g., toxoplasmosis, histoplasmosis) is known; instead, code to the specific etiology.
• If later documentation provides a specific cause, update the diagnosis to the more precise code.
