Apparently this is intended to mean Electo-Sensitivity. It is safe to say that just about every disease known to man now has a code.
Medical insurance requires it.
The coding clerk in a Veterans Administration hospital was contacted last week. It seems to me that a valuable service will have been rendered if a group of your listees could reach a consensus on just what electro-sensitivity consists of. Such a consensus just might, eventually, evoke a recognition of this entity by the planet's medical establishment.
