S82: Fracture of lower leg, including ankle
S82 is a non-billable header ICD-10-CM code for fracture of lower leg, including ankle. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

- G
- subsequent encounter for closed fracture with delayed healing
- H

- N
- subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
- P
- subsequent encounter for closed fracture with malunion
- Q
- subsequent encounter for open fracture type I or II with malunion
- R

Excludes1: never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- traumatic amputation of lower leg (S88.-)
Excludes2: not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Includes
Conditions this code covers.
- fracture of malleolus
Notes
Additional guidance from the ICD-10-CM tabular list.
- 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
