Z57.31

Occupational exposure to environmental tobacco smoke

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

Code Description

ICD-10 Z57.31 is a billable code used to indicate a diagnosis of occupational exposure to environmental tobacco smoke.

Key Diagnostic Point:

Z57.31 is used to indicate a patient's occupational exposure to environmental tobacco smoke (ETS), which is a significant health risk factor. This exposure can lead to various health issues, including respiratory problems, cardiovascular diseases, and increased risk of cancer. The clinical context for this code involves understanding the patient's work environment, where they may be exposed to ETS, often in settings such as bars, restaurants, or workplaces where smoking is prevalent. Social determinants of health play a crucial role, as individuals in lower socioeconomic positions may have higher exposure due to less control over their work environments. Preventive care strategies include educating patients about the risks of ETS, encouraging smoking cessation programs, and advocating for smoke-free workplace policies. Screening for related health issues, such as respiratory function tests, may also be warranted. Aftercare may involve follow-up visits to monitor any health changes related to ETS exposure.

  • It is important to sequence this code appropriately, often as a secondary diagnosis, following the primary diagnosis related to health issues caused by the exposure
  • Payer requirements may vary, so it is essential to check specific guidelines
