Not billableICD-10-CM diagnosis code.

H70.002 Acute mastoiditis without complications, left ear
H70.003 Acute mastoiditis without complications, bilateral

What has happened to this code

Every change the publisher made, from 2012 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.
