Fracture of medial malleolus
Not billableICD-10-CM diagnosis code.
This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.
Submit one of these 6 more specific codes instead:
- S82.51 Displaced fracture of medial malleolus of right tibia (also a header)
- S82.52 Displaced fracture of medial malleolus of left tibia (also a header)
- S82.53 Displaced fracture of medial malleolus of unspecified tibia (also a header)
- S82.54 Nondisplaced fracture of medial malleolus of right tibia (also a header)
- S82.55 Nondisplaced fracture of medial malleolus of left tibia (also a header)
- S82.56 Nondisplaced fracture of medial malleolus of unspecified tibia (also a header)
This code requires a seventh character. See the rule below.
What has happened to this code
Every change the publisher made, from 2012 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.
- FY2012 Added to the draft code set draft Fracture of medial malleolus
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

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 > tibia > malleolus
- Fracture, traumatic > tibia > involving ankle or malleolus
- Fracture, traumatic > ankle > medial malleolus
- Fracture, traumatic > ankle > medial malleolus > nondisplaced
