S42.421

Displaced comminuted supracondylar fracture without intercondylar fracture 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:

  • S42.421A Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, initial encounter for closed fracture
  • S42.421B Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, initial encounter for open fracture
  • S42.421D Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, subsequent encounter for fracture with routine healing
  • S42.421G Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, subsequent encounter for fracture with delayed healing
  • S42.421K Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, subsequent encounter for fracture with nonunion
  • S42.421P Displaced comminuted supracondylar fracture without intercondylar fracture of right humerus, subsequent encounter for fracture with malunion
  • S42.421S Displaced comminuted supracondylar fracture without intercondylar fracture 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.

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.
