ICD-10 Code B58.09 – Other toxoplasma oculopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B58.09 – Other toxoplasma oculopathy
What it is
B58.09 identifies ocular disease caused by Toxoplasma infection when the documentation specifies another toxoplasma oculopathy. Use it for eye involvement that is not captured by a more specific toxoplasmosis code.
Clinical signs
Findings may include ocular inflammation, blurred vision, eye pain, floaters, or decreased visual acuity. Clinical features vary; refer to documentation and ophthalmology assessment for the exact site and severity.
When to use this code
Use this code when the provider documents toxoplasma-related eye disease and does not specify a more exact ocular diagnosis. It is appropriate for charted toxoplasma chorioretinitis or similar eye involvement only if the record supports this “other” category. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use it for toxoplasmosis without eye involvement, or when a more specific toxoplasma eye code is documented. Do not assign it for nonspecific visual complaints without confirmed toxoplasma oculopathy.
Coding tip
Match the code to the documented ocular manifestation and confirm that toxoplasma is the stated cause.
