Toxoplasma chorioretinitis

This code represents an inflammatory condition of the choroid and retina caused by Toxoplasma gondii infection. It is a specific manifestation of toxoplasmosis affecting the posterior segment of the eye, often leading to vision impairment.

Use this code for documented cases of chorioretinitis where the etiology is confirmed or strongly suspected to be toxoplasmosis. This typically occurs in patients with active lesions, scarring, or positive serology for Toxoplasma gondii in conjunction with ophthalmic findings.

• Ensure documentation specifies chorioretinitis and links it to toxoplasmosis, rather than a general chorioretinitis.
• Consider co-reporting with codes for systemic toxoplasmosis (e.g., B58.9) if the infection is disseminated.
• Distinguish from other causes of chorioretinitis, such as viral or autoimmune etiologies, which have different ICD-10-CM codes.
