2026 ICD-10-CM Diagnosis Code S82Fracture of lower leg, including ankle
S82 is a non-billable ICD-10-CM category code for fracture of lower leg, including ankle, so it cannot be submitted on claims. Use a more specific code from this category instead, such as S82.001A, S82.001B, S82.001C, and S82.001D.

Coding GuidelinesGuidance
The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site, to the level of detail furnished by medical record content.
A fracture not indicated as open or closed should be coded to closed. A fracture not indicated whether displaced or not displaced should be coded to displaced.
Initial vs. Subsequent Encounter for Fractures
Traumatic fractures are coded using the appropriate 7th character for initial encounter (A, B, C) while the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.
Fractures are coded using the appropriate 7th character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.
Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.
Care of complications of fractures, such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion (K, M, N) or subsequent care with malunion (P, Q, R).
The open fracture designations in the assignment of the 7th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the 7th character for open fracture type I or II should be assigned (B, E, H, M, Q).

- E - subsequent encounter for open fracture type I or II with routine healing
- F - subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
- G - subsequent encounter for closed fracture with delayed healing
- H - subsequent encounter for open fracture type I or II with delayed healing
- J - subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
- K - subsequent encounter for closed fracture with nonunion
- M - subsequent encounter for open fracture type I or II with nonunion
- 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 - subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
- S - sequela
- 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
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
Indicates that a seventh character is to be assigned to codes in a subcategory.

Fractures
A fracture is a break in a bone. Fractures are usually caused by injuries. Since they can sometimes be serious, it's important to get medical care right away if you think you have a fracture.

Questions About S82Overview
Is S82 (Fracture of lower leg, including ankle) a billable code?
No. This is a category header that groups the codes for fracture of lower leg, including ankle, and headers cannot be submitted on claims. Claims for fracture of lower leg, including ankle need a more specific code from this category, such as S82.001A, S82.001B, and S82.001C.
