This is a tricky one. I actually don't call my chemical hypersensitivity MCS. I have a Toxic Injury. One of the symptoms of my Toxic Injury hapoens to be chemicall hypersensitivity. There are multiple codes for Toxic Effects. They are listed under IDC 10 T51-T65.
The
US does not currently recognize it (that I'm aware of) but Germany, Austria and Japan do under the "Toxic Effects" headings.
