Submit one of these 2 more specific codes instead:

C88.20 Heavy chain disease not having achieved remission
C88.21 Heavy chain disease, in remission

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 Gamma heavy chain disease
FY2010 Draft description revised draft ~~Gamma heavy chain disease~~ Other heavy chain disease
FY2011 Draft description revised draft ~~Other heavy chain disease~~ Heavy chain disease
FY2025 Stopped being billable
