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 Thrombotic microangiopathy
FY2022 Stopped being billable
