In an article confirming this, CMS noted that the mandatory use of ICD-10 pertains to health plans covered by HIPAA. For other types of insurance such as automobile, home or workman’s compensation, which are not covered by HIPAA, most of these insurers have indicated they intend to stay with ICD-9.
This means that if you are caring for a patient who develops a work-related allergy disease covered by worker’s compensation, and if you see them for care for these illnesses, you will need to use your ICD-9 codes indefinitely.
