Chorioretinitis due to toxoplasmosis

This code represents inflammation of the choroid and retina of the eye caused by infection with the parasite Toxoplasma gondii. This condition can lead to vision impairment, scotomas, and, in severe cases, blindness, often presenting as recurrent episodes. It is a significant ocular manifestation of toxoplasmosis.

This code is appropriate for documenting active or inactive chorioretinitis specifically attributed to a confirmed or suspected toxoplasmosis infection. Documentation should clearly state the diagnosis of chorioretinitis and its etiology as toxoplasmosis, often supported by serological testing or characteristic funduscopic findings.

• Ensure documentation explicitly links chorioretinitis to toxoplasmosis; avoid using for chorioretinitis of unknown or other etiologies.
• Consider sequencing this code as a primary diagnosis when chorioretinitis is the main reason for the encounter, or as a secondary diagnosis when it's a comorbidity.
• Do not confuse with other forms of chorioretinitis (e.g., viral, bacterial, autoimmune) which have distinct ICD-9-CM codes.
