I’m researching a condition called multiple chemical sensitivities. The who do not recognise it as a physical disease. Some countries do not recognise it as a physical disease but others do eg Germany and japan recognise it as a physical disease. Japan uses the code icd10. T65.
Having googled it seems icd10 is a classification used for mental health disorders. What I don’t get is if Japan recognise it as a physical disease why t65 which stands for toxic injury why is it listed as icd10 t65 as I believe the former is mental health.
