Unspecified fracture of the lower end of left radius

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:

S52.502A Unspecified fracture of the lower end of left radius, initial encounter for closed fracture
S52.502B Unspecified fracture of the lower end of left radius, initial encounter for open fracture type I or II
S52.502C Unspecified fracture of the lower end of left radius, initial encounter for open fracture type IIIA, IIIB, or IIIC
S52.502D Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture with routine healing
S52.502E Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type I or II with routine healing
S52.502F Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
S52.502G Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture with delayed healing
S52.502H Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type I or II with delayed healing
S52.502J Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
S52.502K Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture with nonunion
S52.502M Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type I or II with nonunion
S52.502N Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
S52.502P Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture with malunion
S52.502Q Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type I or II with malunion
S52.502R Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
S52.502S Unspecified fracture of the lower end of left radius, 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.

Fracture, traumatic > radius > distal end
Fracture, traumatic > radius > lower end
