Exposure to other noise, sequela

This code signifies a long-term or residual health condition resulting from exposure to a type of noise not otherwise specified. It indicates that the acute phase of the noise exposure has passed, and the patient is now experiencing a lasting consequence, such as chronic tinnitus or noise-induced hearing loss, where the specific noise source is unknown or unclassifiable.

Apply this code when documenting a sequela of noise exposure where the specific type of noise (e.g., occupational, recreational) is not documented or cannot be determined. This is appropriate for patients presenting with chronic conditions directly attributed to a past, unspecified noise event.

• Always sequence this code after the code identifying the specific sequela (e.g., H90.3- for sensorineural hearing loss).
• Ensure documentation clearly links the current condition to a past, unspecified noise exposure.
• Avoid using this code if a more specific noise exposure code (e.g., W42.0XXS, W42.1XXS) can be supported by the medical record.
