Z57.4

Occupational exposure to toxic agents in agriculture

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z57.4 is a billable code used to indicate a diagnosis of occupational exposure to toxic agents in agriculture.

Key Diagnostic Point:

Z57.4 refers to occupational exposure to toxic agents specifically in the agricultural sector, which can include pesticides, herbicides, and other hazardous chemicals used in farming. This exposure can lead to various health issues, including respiratory problems, skin conditions, and long-term chronic diseases. The social determinants of health play a significant role in this context, as agricultural workers often face socioeconomic challenges, limited access to healthcare, and inadequate safety measures. Preventive care is crucial, including regular health screenings for early detection of exposure-related conditions, education on safe handling practices, and access to protective equipment. Aftercare may involve ongoing monitoring and management of health conditions resulting from exposure. Proper documentation of exposure history and health status is essential for effective coding and care management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of toxic agents and their health impacts
  • Need for detailed exposure history documentation
  • Potential for co-existing health conditions
  • Variability in state and federal reporting requirements

Audit Risk Factors

  • Inadequate documentation of exposure history
  • Failure to link health conditions to occupational exposure
  • Misclassification of exposure type
  • Lack of preventive care documentation

Specialty Focus

Medical Specialties

Primary Care

Documentation Requirements

Documentation should include patient history of occupational exposure, symptoms, and preventive measures taken.

Common Clinical Scenarios

Routine checkups for agricultural workers, screenings for respiratory issues, and follow-up visits for chronic conditions.

Billing Considerations

Consideration of social determinants such as access to healthcare, education on safety practices, and socioeconomic status.

Public Health

Documentation Requirements

Documentation should include population-level data on exposure incidents, health outcomes, and preventive interventions.

Common Clinical Scenarios

Epidemiological studies on pesticide exposure, community health screenings, and health education programs.

Billing Considerations

Focus on tracking health status trends and implementing community-wide preventive measures.

Coding Guidelines

Inclusion Criteria

Use Z57.4 When
  • Z codes are used when a patient encounters health services for reasons other than a current illness or injury
  • 4 should be used when there is a documented occupational exposure to toxic agents in agriculture, and it may be sequenced as a secondary diagnosis when coding for related health conditions
  • Payer requirements may vary, so it is essential to verify coverage for preventive services related to occupational exposure

Exclusion Criteria

Do NOT use Z57.4 When
No specific exclusions found.
