D75.822 Immune-mediated heparin-induced thrombocytopenia
D75.828 Other heparin-induced thrombocytopenia syndrome
D75.829 Heparin-induced thrombocytopenia, unspecified

What has happened to this code

Every change the publisher made, from 2010 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.

FY2010 Added to the draft code set draft Heparin induced thrombocytopenia (HIT)
FY2023 Stopped being billable
