Cntct w and expsr to environ tobacco smoke (acute) (chronic)

This code identifies a patient's documented exposure to environmental tobacco smoke, often referred to as secondhand smoke, which can be either acute or chronic. It signifies that the patient has been in contact with tobacco smoke from others, rather than actively using tobacco products themselves.

Use this code when a patient's medical record indicates exposure to secondhand smoke, and this exposure is considered relevant to their current health status or risk factors. This could include pediatric patients exposed at home or adults with respiratory conditions exacerbated by passive smoking.

• Do not code for active tobacco use or nicotine dependence; those have separate codes.
• Ensure the documentation clearly specifies "environmental tobacco smoke" or "secondhand smoke" exposure.
• Distinguish from occupational exposure, which has a specific Excludes2 code.
