ICD-10-CM › S00-T88 › S80-S89 › S82.0 Fracture of patella › S82.00

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 3 more specific codes instead:

• S82.001 Unspecified fracture of right patella (also a header)
• S82.002 Unspecified fracture of left patella (also a header)
• S82.009 Unspecified fracture of unspecified patella (also a header)

This code requires a seventh character. See the rule below.

What has happened to this code

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)

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.

• Broken > leg
• Injury > leg > fracture
• Fracture, traumatic > knee cap
• Fracture, traumatic > leg > patella
• Fracture, traumatic > patella
