Code Description

ICD-10 B55.9 is a billable code used to indicate a diagnosis of leishmaniasis, unspecified.

Key Diagnostic Point:

Leishmaniasis is a parasitic disease caused by protozoa of the genus Leishmania, which are transmitted to humans through the bite of infected sandflies. The disease manifests in various forms, including cutaneous leishmaniasis, which causes skin lesions, and visceral leishmaniasis, which affects internal organs. The unspecified code B55.9 is used when the specific type of leishmaniasis is not documented. Symptoms may include fever, weight loss, anemia, and splenomegaly in visceral cases, while cutaneous forms present with ulcers and skin lesions. Diagnosis is typically confirmed through serological tests, PCR, or biopsy. Treatment varies based on the form of the disease and may include antimonial compounds, amphotericin B, or miltefosine. The disease is endemic in tropical and subtropical regions, making it a significant public health concern in these areas.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of clinical presentations (cutaneous vs. visceral)
  • Need for specific diagnostic criteria
  • Potential for co-infections (e.g., HIV)
  • Variability in treatment protocols based on disease form

Audit Risk Factors

  • Inadequate documentation of specific leishmaniasis type
  • Misuse of unspecified code when specific diagnosis is available
  • Failure to document travel history to endemic areas
  • Lack of supporting lab results or clinical findings

Specialty Focus

Medical Specialties

Infectious Disease

Documentation Requirements

Detailed patient history, travel history, lab results, and clinical findings.

Common Clinical Scenarios

Patients presenting with fever, weight loss, and skin lesions after travel to endemic regions.

Billing Considerations

Ensure specificity in documentation to avoid using the unspecified code when a specific type is known.

Dermatology

Documentation Requirements

Photographic evidence of skin lesions, biopsy results, and treatment response.

Common Clinical Scenarios

Patients with cutaneous leishmaniasis presenting with ulcerative lesions.

Billing Considerations

Document the location, size, and characteristics of lesions to support coding.

Coding Guidelines

Inclusion Criteria

  • According to ICD
  • 10 guidelines, B55
  • 9 should be used when the specific type of leishmaniasis is not documented
  • Coders should ensure that all relevant clinical information is captured to support the use of this code

Exclusion Criteria

Do NOT use B55.9 When
No specific exclusions found.

Pathology examination of tissue

Clinical Scenario

Used when a biopsy is performed to confirm leishmaniasis.

Documentation Requirements

Pathology report and clinical notes indicating the need for biopsy.

Specialty Considerations

Infectious disease specialists should ensure that the biopsy results are clearly linked to the diagnosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding leishmaniasis, enabling better tracking of disease prevalence and treatment outcomes. The introduction of specific codes for cutaneous and visceral forms has improved the accuracy of coding practices.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding leishmaniasis, enabling better tracking of disease prevalence and treatment outcomes. The introduction of specific codes for cutaneous and visceral forms has improved the accuracy of coding practices.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding leishmaniasis, enabling better tracking of disease prevalence and treatment outcomes. The introduction of specific codes for cutaneous and visceral forms has improved the accuracy of coding practices.

Frequently Asked Questions

When should I use B55.9?

Use B55.9 when the specific type of leishmaniasis is not documented in the medical record. Ensure that all relevant clinical information is captured to support this code.

What are the common treatments for leishmaniasis?

Common treatments include antimonial compounds, amphotericin B, and miltefosine, depending on the form of the disease.
