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.

Inherited from Q20 Congenital malformations of cardiac chambers and connections
Excludes1 - never coded here
- dextrocardia with situs inversus (Q89.3)
- mirror-image atrial arrangement with situs inversus (Q89.3)
