Z57.31 Occupational exposure to environmental tobacco smoke

ICD10CM code

#### Name of the Condition
- Occupational exposure to environmental tobacco smoke (ETS)
- Also known as secondhand smoke exposure at work

#### Summary
- **Occupational exposure to environmental tobacco smoke** refers to inhaling smoke from other people's cigarettes, cigars, or pipes while at work. This type of exposure is linked to various health issues, even if the person exposed isn't an active smoker.

#### Causes
- The primary cause is the presence of tobacco smoke in the workplace, usually from smoking colleagues or customers, in enclosed or poorly ventilated spaces.

#### Risk Factors
- Working in environments where smoking indoors is permitted.
- Occupations in hospitality and entertainment sectors, such as bars or casinos, where smoking may be more prevalent.

#### Symptoms
- Symptoms may include irritation of the eyes, nose, and throat, coughing, shortness of breath, and in some cases, exacerbation of asthma and other respiratory conditions.

#### Diagnosis
- Diagnosis typically involves assessing the patient's occupational history, symptoms, and sometimes measuring levels of cotinine (a nicotine by-product) in the blood or urine.

#### Treatment Options
- Treatment focuses on reducing exposure, using air purifiers, and implementing smoke-free workplace policies.
- Symptomatic relief may involve medications such as bronchodilators for respiratory symptoms.

#### Prognosis and Follow-Up
- Prospect for resolution of symptoms is good if exposure is minimized or eliminated.
- Regular follow-up is necessary to monitor persistent or worsening symptoms and adherence to workplace safety measures.

#### Complications
- Chronic exposure can lead to severe respiratory conditions, cardiovascular disease, or cancer over time.
- Increased absenteeism or reduced work performance due to health issues.

#### Lifestyle & Prevention
- Workplace policies enforcing smoke-free zones.
- Personal lifestyle habits such as avoiding smoking themselves and advocating for smoke-free environments can reduce health risks.

#### When to Seek Professional Help
- Seek medical attention if experiencing persistent respiratory symptoms, chest pain, or signs of worsening exposure despite preventive measures.

#### Tips for Medical Coders
- Ensure the work-related aspect of exposure is documented.
- Distinguish between exposure types to avoid misclassification, as this code specifically pertains to occupational settings.
