Not billableICD-10-CM diagnosis code.
This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.
Submit one of these 3 more specific codes instead:
- S04.30 Injury of trigeminal nerve, unspecified side (also a header)
- S04.31 Injury of trigeminal nerve, right side (also a header)
- S04.32 Injury of trigeminal nerve, left side (also a header)
This code requires a seventh character. See the rule below.
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.
