I just found this in DSM and it predates the last FND meeting by several years so Prof Stone did not need to cave in to the American psychiatrists regarding the removal of FND from DSM.
'There are no DSM codes. The codes appearing in DSM-5 in addition to the ICD-10-CM codes were ICD-9 codes. These codes are no longer valid since ICD-10-CM codes replaced them in the United States starting October 1, 2015. Clinicians should use ICD-10-CM codes to submit claims.'
On that basis - and for many other reasons - I feel that FND does not have a place in DSM and the psychiatrists involved with it need to turn their attention to the health care providers/professionals who are scornful of people with FND since that can't be good for their (the providers) psyches and we know it's not good for patients, whatever condition we have.
