B52.8

Toxoplasmosis due to other specified organisms

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 B52.8 is a billable code used to indicate a diagnosis of toxoplasmosis due to other specified organisms.

Key Diagnostic Point:

Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii, which can lead to severe complications, particularly in immunocompromised individuals. The ICD-10 code B52.8 specifically refers to cases of toxoplasmosis that are attributed to other specified organisms, which may include atypical strains or related protozoa. The clinical presentation can vary widely, from asymptomatic cases to severe manifestations such as encephalitis, chorioretinitis, and systemic illness. Diagnosis typically involves serological testing for T. gondii antibodies, but in cases of atypical organisms, additional laboratory identification may be necessary. Treatment often includes antiparasitic medications, and in cases of resistance or atypical presentations, alternative therapies may be required. Understanding the specific organism involved is crucial for effective management and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Identification of the specific organism causing the toxoplasmosis.
  • Differentiation from other parasitic infections such as malaria.
  • Potential for co-infection with other pathogens.
  • Variability in clinical presentation and severity.

Audit Risk Factors

  • Inadequate documentation of the specific organism.
  • Failure to document the clinical rationale for the diagnosis.
  • Lack of supporting laboratory results.
  • Misclassification of the infection type.

Specialty Focus

Infectious Disease

Documentation Requirements

Detailed laboratory results, clinical notes on symptoms, and treatment plans.

Common Clinical Scenarios

Patients presenting with fever, neurological symptoms, or ocular issues.

Billing Considerations

Documentation must clearly indicate the organism and any atypical findings.

Ophthalmology

Documentation Requirements

Visual acuity tests, imaging studies, and treatment responses.

Common Clinical Scenarios

Patients with chorioretinitis or other ocular manifestations.

Billing Considerations

Ensure linkage between ocular symptoms and the underlying infectious cause.

Frequently Asked Questions

What is the significance of coding B52.8?

Coding B52.8 is important for accurately capturing cases of toxoplasmosis caused by organisms other than Toxoplasma gondii, which can have different clinical implications and treatment needs.
