S52.046

Nondisplaced fracture of coronoid process of unspecified ulna

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 16 more specific codes instead:

  • S52.046A Nondisplaced fracture of coronoid process of unspecified ulna, initial encounter for closed fracture
  • S52.046B Nondisplaced fracture of coronoid process of unspecified ulna, initial encounter for open fracture type I or II
  • S52.046C Nondisplaced fracture of coronoid process of unspecified ulna, initial encounter for open fracture type IIIA, IIIB, or IIIC
  • S52.046D Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for closed fracture with routine healing
  • S52.046E Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type I or II with routine healing
  • S52.046F Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
  • S52.046G Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for closed fracture with delayed healing
  • S52.046H Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type I or II with delayed healing
  • S52.046J Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
  • S52.046K Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for closed fracture with nonunion
  • S52.046M Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type I or II with nonunion
  • S52.046N Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
  • S52.046P Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for closed fracture with malunion
  • S52.046Q Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type I or II with malunion
  • S52.046R Nondisplaced fracture of coronoid process of unspecified ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
  • S52.046S Nondisplaced fracture of coronoid process of unspecified ulna, 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.

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.

Inherited from S52 Fracture of forearm

Seventh character required

  • The appropriate 7th character is to be added to all codes from category S52

Seventh character values

  • initial encounter for open fracture NOS

Excludes1 - never coded here

  • traumatic amputation of forearm (S58.-)

Excludes2 - not included here

  • fracture at wrist and hand level (S62.-)
  • periprosthetic fracture around internal prosthetic elbow joint (M97.4)

Note

  • A fracture not indicated as displaced or nondisplaced should be coded to displaced
  • A fracture not indicated as open or closed should be coded to closed
  • The open fracture designations are based on the Gustilo open fracture classification

Inherited from the S50-S59 section Injuries to the elbow and forearm (S50-S59)

Excludes2 - not included here

  • burns and corrosions (T20-T32)
  • frostbite (T33-T34)
  • injuries of wrist and hand (S60-S69)
  • insect bite or sting, venomous (T63.4)

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.
