Orbital myositis

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 4 more specific codes instead:

H05.121 Orbital myositis, right orbit
H05.122 Orbital myositis, left orbit
H05.123 Orbital myositis, bilateral
H05.129 Orbital myositis, unspecified orbit

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.

FY2012 Added to the draft code set draft Orbital myositis

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 H05 Disorders of orbit

Excludes1 - never coded here

congenital malformation of orbit (Q10.7)

Inherited from the H00-H05 section Disorders of eyelid, lacrimal system and orbit (H00-H05)

Excludes2 - not included here

open wound of eyelid (S01.1-)
superficial injury of eyelid (S00.1-, S00.2-)

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.
