Contact with and (suspected) exposure to noise

This code signifies that a patient has had an encounter with, or is believed to have been exposed to, excessive or harmful levels of noise. This exposure is considered a potential risk factor for noise-induced hearing loss or other noise-related health issues.

Use this code when documenting a patient's history of noise exposure, particularly in occupational health settings, or when evaluating a patient for symptoms potentially linked to noise. It is appropriate for cases where the exposure is suspected to be a contributing factor to their current condition or for preventative screening.

• Always code this as a secondary diagnosis, as it describes an exposure, not a definitive condition.
• Consider using in conjunction with codes for hearing loss (e.g., H90.x) if a diagnosis has been established.
• Do not use if the noise exposure is incidental and not clinically relevant to the patient's care.
