Displaced fracture (avulsion) of lateral epicondyle of right humerus

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:

S42.431A Displaced fracture (avulsion) of lateral epicondyle of right humerus, initial encounter for closed fracture
S42.431B Displaced fracture (avulsion) of lateral epicondyle of right humerus, initial encounter for open fracture
S42.431D Displaced fracture (avulsion) of lateral epicondyle of right humerus, subsequent encounter for fracture with routine healing
S42.431G Displaced fracture (avulsion) of lateral epicondyle of right humerus, subsequent encounter for fracture with delayed healing
S42.431K Displaced fracture (avulsion) of lateral epicondyle of right humerus, subsequent encounter for fracture with nonunion
S42.431P Displaced fracture (avulsion) of lateral epicondyle of right humerus, subsequent encounter for fracture with malunion
S42.431S Displaced fracture (avulsion) of lateral epicondyle of right humerus, 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 Displaced fracture (avulsion) of lateral epicondyle of right humerus

Official coding rules

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.

Fracture, traumatic > humerus > distal end
Fracture, traumatic > supracondylar, elbow
Fracture, traumatic > humerus > intercondylar
Fracture, traumatic > humerus > supracondylar
Fracture, traumatic > humerus > articular process
Fracture, traumatic > humerus > lower end > supracondylar > with intercondylar fracture
Fracture, traumatic > humerus > lower end > epicondyle > lateral
Fracture, traumatic > humerus > lower end > epicondyle > lateral > nondisplaced
