2024 ICD-10-CM Diagnosis Code B58.8

Specific Coding Applicable to Toxoplasmosis with other organ involvement

Non-specific codes like B58.8 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for toxoplasmosis with other organ involvement:

Clinical Information

• 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, 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)

• 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.

• Toxoplasma

  a genus of protozoa parasitic to birds and mammals. t. gondii is one of the most common infectious pathogenic animal parasites of man.

• Adult Acquired Toxoplasmosis

  toxoplasmosis acquired in adulthood.

• Aicardi-Goutieres Syndrome 1|AGS1|Cree Encephalitis|Encephalopathy, Familial Infantile, with Intracranial Calcification and Chronic Cerebrospinal Fluid Lymphocytosis|Pseudotoxoplasmosis Syndrome

  a heritable condition, caused by mutation(s) in the trex1 gene, encoding three-prime repair exonuclease 1. clinical features and onset may vary significantly, but is characterized in its most severe form by cerebral atrophy, leukodystrophy, intracranial calcifications, chronic cerebrospinal fluid (csf) lymphocytosis, and increased concentrations of csf alpha-interferon.

• Congenital Toxoplasmosis

  toxoplasma infection that is present from birth.

• Cordonnier Grade 2 Parasitic Complication, Toxoplasmosis Infection without Organ Involvement|Cordonnier Grade 2 Parasitic Complication|Grade 2 Toxoplasmosis Infection without Organ Involvement

  any toxoplasmosis infection without organ involvement.

• Cordonnier Grade 3 Parasitic Complication, Central Nervous System or Other Organ Toxoplasmosis|Grade 3 CNS or Other Organ Toxoplasmosis

  any toxoplasmosis infection with central nervous system involvement or other organ involvement.

• Nephrotic Syndrome - Toxoplasmosis Associated|Toxoplasmosis Associated Nephrotic Syndrome

  nephrotic syndrome associated with a toxoplasmosis infection.

• TORCH Antibody Measurement|Toxoplasmosis, Other Infections, Rubella, Cytomegalovirus, and Herpes Simplex Virus (TORCH) Antibody Panel Measurement

  a group of blood tests used to detect antibodies to toxoplasma gondii, rubella, cytomegalovirus, and herpes simplex virus to rule out congenital infections. a group of other infections may be tested as well, including varicella-zoster virus, hepatitis b virus, human immunodeficiency virus, parvovirus b19, and syphilis.

• TORCH Syndrome|TORCH Infection|Toxoplasmosis, Other Infections, Rubella, Cytomegalovirus, and Herpes Simplex Virus (TORCH) Syndrome

  a syndrome that results from a group of infections that affect the fetus or the newborn. the group of infections includes toxoplasma gondii, rubella, cytomegalovirus, herpes simplex virus, and other infections. the other infections include varicella-zoster virus, hepatitis b virus, human immunodeficiency virus, parvovirus b19, and syphilis. signs and symptoms include fever, feeding difficulties, petechial rash, jaundice, hepatosplenomegaly, chorioretinitis, and microcephaly.

• Toxoplasmosis

  a parasitic disease contracted by the ingestion or fetal transmission of toxoplasma gondii.
