Toxoplasmosis due to other specified infectious agent

Code Description

ICD-10 B58.8 is a billable code used to indicate a diagnosis of toxoplasmosis due to other specified infectious agent.

Key Diagnostic Point:

Toxoplasmosis is an infection caused by the protozoan parasite Toxoplasma gondii, which can be transmitted through various routes including ingestion of undercooked meat, contaminated water, or contact with infected cat feces. While T. gondii is the most common cause of toxoplasmosis, this code is used when the infection is due to other specified infectious agents, which may include atypical strains or related protozoa. Clinically, toxoplasmosis can present with flu-like symptoms, lymphadenopathy, and in severe cases, can lead to encephalitis, particularly in immunocompromised individuals such as those with HIV/AIDS. Diagnosis is typically confirmed through serological testing for Toxoplasma antibodies or PCR testing. Treatment often involves the use of pyrimethamine and sulfadiazine, along with leucovorin to mitigate bone marrow suppression. In pregnant women, the management of toxoplasmosis is critical to prevent congenital transmission, which can lead to serious fetal complications. Understanding the specific infectious agent involved is essential for appropriate treatment and management.

Complexity Factors

  • Identification of the specific infectious agent causing the toxoplasmosis.
  • Differentiation from other protozoal infections.
  • Documentation of patient history and exposure risks.
  • Understanding of serological and PCR testing results.

Audit Risk Factors

  • Inadequate documentation of the specific infectious agent.
  • Failure to document patient symptoms and history.
  • Misclassification of the infection type.
  • Lack of clarity in treatment protocols followed.
