ICD-10 Code B58.0 – Toxoplasma oculopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B58.0 – Toxoplasma oculopathy
What it is
B58.0 identifies eye disease caused by Toxoplasma infection. Use it when toxoplasmosis affects ocular structures, such as the retina or choroid, rather than a generalized infection.
Clinical signs
Typical findings include blurred vision, floaters, eye pain, photophobia, or decreased visual acuity. Clinical features vary; refer to documentation for evidence of ocular inflammation or retinal lesions linked to toxoplasmosis.
When to use this code
Use B58.0 when the provider documents toxoplasma involvement of the eye, including ocular toxoplasmosis, toxoplasmic retinochoroiditis, or similar wording. It is appropriate when the record supports an eye-specific manifestation rather than nonspecific infection. If documentation is unclear, check documentation.
Do not use for
Do not use this code for toxoplasmosis without eye involvement or for other causes of uveitis or retinitis. If the chart does not clearly link the eye findings to Toxoplasma, do not assume B58.0.
Coding tip
Assign B58.0 only when the ophthalmic manifestation is explicitly documented as toxoplasma-related.
