What has happened to this code

Every change the publisher made, from 2007 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2007 Added to the draft code set draft Unspecified follicular non-Hodgkin's lymphoma, unspecified, intra-abdominal lymph nodes
FY2010 Draft description revised draft ~~Unspecified follicular non-Hodgkin's lymphoma, unspecified, intra-abdominal lymph nodes~~ Follicular lymphoma, unspecified, intra-abdominal lymph nodes
