It's more an impression. In Germany nearly never ME is used, not even by "experts", elsewhere at least the term ME/CFS. So there, ME is not unknown. Thanks for pointing to SNOMED CT, never heard of this one before. "Chronic fatigue" is listed as R53.82, and it excludes postviral fatigue syndrome (G93.3), with "Approximate Synonyms" CFS. So, actually, here is an extra code for CFS, which I didn't know. So, is your proposal referring to positioning this CFS section (now R53.82 ) to the G-section? As I understood, chronic fatigue is something that might also occurr after chemo (I guess the rate was ca. 70%), in MS, Aids and others. Again, I learned something new! Why then, for God's sake, are ME and CFS (ME/CFS) used as synonyms by officials and doctors...? Or is this just a German problem, that both aren't distinguished? Obviously, WHO has the standpoint they are distinct illnesses. This means, we should get active here, right, in order to guarantee they won't do mischief? If so, how? Or will your work as a team include this? How will it be in other countries?
