Abnormal jaw closure
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
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 Abnormal jaw closure
Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from the M26-M27 section Dentofacial anomalies [including malocclusion] and other disorders of jaw (M26-M27)
Excludes1 - never coded here
- hemifacial atrophy or hypertrophy (Q67.4)
- unilateral condylar hyperplasia or hypoplasia (M27.8)
How CDC's index refers to this code
Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
