Lateral dislocation of proximal end of tibia, unspecified knee

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 3 more specific codes instead:

S83.146A Lateral dislocation of proximal end of tibia, unspecified knee, initial encounter
S83.146D Lateral dislocation of proximal end of tibia, unspecified knee, subsequent encounter
S83.146S Lateral dislocation of proximal end of tibia, unspecified knee, 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 dislocation of proximal end of tibia, unspecified knee

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.
