S82.046

Nondisplaced comminuted fracture of unspecified patella

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:

  • S82.046A Nondisplaced comminuted fracture of unspecified patella, initial encounter for closed fracture
  • S82.046B Nondisplaced comminuted fracture of unspecified patella, initial encounter for open fracture type I or II
  • S82.046C Nondisplaced comminuted fracture of unspecified patella, initial encounter for open fracture type IIIA, IIIB, or IIIC
  • S82.046D Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for closed fracture with routine healing
  • S82.046E Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type I or II with routine healing
  • S82.046F Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
  • S82.046G Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for closed fracture with delayed healing
  • S82.046H Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type I or II with delayed healing
  • S82.046J Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
  • S82.046K Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for closed fracture with nonunion
  • S82.046M Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type I or II with nonunion
  • S82.046N Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
  • S82.046P Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for closed fracture with malunion
  • S82.046Q Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type I or II with malunion
  • S82.046R Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
  • S82.046S Nondisplaced comminuted fracture of unspecified patella, sequela

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 S82 Fracture of lower leg, including ankle

Seventh character required

  • The appropriate 7th character is to be added to all codes from category S82

Seventh character values

  • initial encounter for open fracture NOS

Excludes1 - never coded here

  • traumatic amputation of lower leg (S88.-)

Excludes2 - not included here

  • fracture of foot, except ankle (S92.-)
  • periprosthetic fracture around internal prosthetic ankle joint (M97.2)
  • periprosthetic fracture around internal prosthetic implant of knee joint (M97.1-)

Includes

  • fracture of malleolus

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 S80-S89 section Injuries to the knee and lower leg (S80-S89)

Excludes2 - not included here

  • burns and corrosions (T20-T32)
  • frostbite (T33-T34)
  • injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99)
  • 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.
