Contact with and (suspected) exposure to mold (toxic)

This code signifies a patient's documented contact with or suspected exposure to toxic mold. It indicates that the patient has been in an environment where harmful mold was present, or there is a reasonable suspicion of such exposure, even if symptoms are not yet present or definitively linked.

Apply this code when a patient reports exposure to mold in their home, workplace, or other environment, particularly when the mold is identified or suspected to be toxic. This is appropriate for initial evaluations following exposure, or when documenting a history of exposure that may be relevant to current symptoms.

• Do not use this code if the patient has a confirmed mold-related illness; instead, code the specific illness.
• This code can be used as a primary or secondary diagnosis, depending on the reason for the encounter.
• Consider additional codes for symptoms or conditions that may be related to the mold exposure.
