Valid for Submission
B58.9 is a billable diagnosis code used to specify a medical diagnosis of toxoplasmosis, unspecified. The code B58.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code B58.9 might also be used to specify conditions or terms like coccidiosis co-occurrent with human immunodeficiency virus infection, infection caused by coccidia co-occurrent with acquired immunodeficiency syndrome, infection caused by toxoplasma, infection caused by toxoplasma gondii co-occurrent with acquired immunodeficiency syndrome, multisystemic disseminated toxoplasmosis , piringer-kuchinka's syndrome, etc.
Unspecified diagnosis codes like B58.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code B58.9 are found in the index:
- - Toxoplasma, toxoplasmosis (acquired) - B58.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Coccidiosis co-occurrent with human immunodeficiency virus infection
- Infection caused by Coccidia co-occurrent with acquired immunodeficiency syndrome
- Infection caused by Toxoplasma
- Infection caused by Toxoplasma gondii co-occurrent with acquired immunodeficiency syndrome
- Multisystemic disseminated toxoplasmosis
- Piringer-Kuchinka's syndrome
- Toxoplasmosis of multiple sites
- TOXOPLASMOSIS-. the acquired form of infection by toxoplasma gondii in animals and man.
- TOXOPLASMOSIS ANIMAL-. acquired infection of non human animals by organisms of the genus toxoplasma.
- TOXOPLASMOSIS CONGENITAL-. prenatal protozoal infection with toxoplasma gondii which is associated with injury to the developing fetal nervous system. the severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. clinical features include hydrocephalus; microcephaly; deafness; cerebral calcifications; seizures; and psychomotor retardation. signs of a systemic infection may also be present at birth including fever rash and hepatosplenomegaly. from adams et al. principles of neurology 6th ed p735
- TOXOPLASMOSIS OCULAR-. infection caused by the protozoan parasite toxoplasma in which there is extensive connective tissue proliferation the retina surrounding the lesions remains normal and the ocular media remain clear. chorioretinitis may be associated with all forms of toxoplasmosis but is usually a late sequel of congenital toxoplasmosis. the severe ocular lesions in infants may lead to blindness.
- TOXOPLASMOSIS CEREBRAL-. infections of the brain caused by the protozoan toxoplasma gondii that primarily arise in individuals with immunologic deficiency syndromes see also aids related opportunistic infections. the infection may involve the brain diffusely or form discrete abscesses. clinical manifestations include seizures altered mentation headache focal neurologic deficits and intracranial hypertension. from joynt clinical neurology 1998 ch27 pp41 3

Information for Patients
Toxoplasmosis is a disease caused by the parasite Toxoplasma gondii. More than 60 million people in the U.S. have the parasite. Most of them don't get sick. But the parasite causes serious problems for some people. These include people with weak immune systems and babies whose mothers become infected for the first time during pregnancy. Problems can include damage to the brain, eyes, and other organs.
You can get toxoplasmosis from
- Waste from an infected cat
- Eating contaminated meat that is raw or not well cooked
- Using utensils or cutting boards after they've had contact with contaminated raw meat
- Drinking infected water
- Receiving an infected organ transplant or blood transfusion
Most people with toxoplasmosis don't need treatment. There are drugs to treat it for pregnant women and people with weak immune systems.
