Lateral subluxation of unspecified patella
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:
- S83.013A Lateral subluxation of unspecified patella, initial encounter
- S83.013D Lateral subluxation of unspecified patella, subsequent encounter
- S83.013S Lateral subluxation of unspecified patella, sequela
This code requires a seventh character. See the rule below.
What has happened to this code
Every change the publisher made, from 2014 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.
- FY2014 Added to the draft code set draft Lateral subluxation of unspecified patella
