Other disorders of middle ear mastoid

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 7 more specific codes instead:

H74.0 Tympanosclerosis (also a header)
H74.1 Adhesive middle ear disease (also a header)
H74.2 Discontinuity and dislocation of ear ossicles (also a header)
H74.3 Other acquired abnormalities of ear ossicles (also a header)
H74.4 Polyp of middle ear (also a header)
H74.8 Other specified disorders of middle ear and mastoid (also a header)
H74.9 Unspecified disorder of middle ear and mastoid (also a header)

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.
