S82
ICD-10Non-billable categoryFracture of lower leg, including ankle
Official ICD-10-CM descriptor (FY2026)
Fracture of lower leg, including ankle
S82 is a category heading, not a billable code. CMS does not accept it on a claim; report one of the more specific codes beneath it.
Includes
- fracture of malleolus
Excludes1
Not coded here. An Excludes1 code should never be reported at the same time as the code above it.
- traumatic amputation of lower leg (S88.-)
Excludes2
Not included here. The condition is not part of this code, but a patient may have both, and both codes may be reported together.
- 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-)
Notes
- 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
7th character
- The appropriate 7th character is to be added to all codes from category S82
