Other specified zoonotic bacterial diseases

BILLABLE STATUSYes

Code Description

ICD-10 A28.8 is a billable code used to indicate a diagnosis of other specified zoonotic bacterial diseases.

Key Diagnostic Point:

Zoonotic bacterial diseases are infections that are transmitted from animals to humans, often through direct contact, bites, or vectors such as insects. The code A28.8 encompasses various zoonotic bacterial diseases that do not fall under more specific categories. These diseases can be caused by a range of bacteria, including but not limited to Brucella, Leptospira, and Francisella. Symptoms may vary widely, from mild flu-like symptoms to severe systemic infections, depending on the pathogen and the host's immune response. Transmission can occur through contaminated food or water, inhalation of aerosols, or direct contact with infected animals or their excretions. Public health considerations are paramount, as zoonotic diseases can lead to outbreaks, particularly in areas where humans and animals interact closely. Surveillance, vaccination of animals, and public education are critical components in managing these diseases and preventing transmission to humans.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of pathogens included under this code
  • Need for precise clinical documentation to specify the disease
  • Potential overlap with other zoonotic disease codes
  • Variability in symptoms and severity requiring careful assessment

Audit Risk Factors

  • Inadequate documentation of the specific zoonotic disease
  • Failure to link symptoms to the zoonotic infection
  • Misclassification of the disease under a more specific code
  • Lack of supporting laboratory results

Specialty Focus

Documentation Requirements

Epidemiological data, outbreak reports, and vaccination status of affected populations.

Common Clinical Scenarios

Monitoring and reporting cases during an outbreak of a zoonotic disease.

Billing Considerations

Focus on community health implications and preventive measures.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more detailed coding of zoonotic diseases, improving tracking and management of these infections. A28.8 provides flexibility for coding unspecified zoonotic bacterial diseases, which can enhance public health reporting.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more detailed coding of zoonotic diseases, improving tracking and management of these infections. A28.8 provides flexibility for coding unspecified zoonotic bacterial diseases, which can enhance public health reporting.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more detailed coding of zoonotic diseases, improving tracking and management of these infections. A28.8 provides flexibility for coding unspecified zoonotic bacterial diseases, which can enhance public health reporting.
