About ICD-10-CM S82
ICD-10-CM code S82 represents Fracture of lower leg, including ankle. This is a non-billable header code in the Injury, Poisoning, and External Causes chapter (block S82). The 2026 edition of ICD-10-CM S82 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Coding Tips for S82
Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.
Injury codes require a 7th character: A (initial encounter, active treatment), D (subsequent, healing/recovery), S (sequela, late effect of original injury). Codes with fewer than 6 characters need the placeholder X to bring them to 6 characters before adding the 7th. Wrong or missing 7th character is the #1 cause of injury claim denials.
Type 1 Excludes
Pure excludes, these codes can never be coded together with S82. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- traumatic amputation of lower leg (S88.-)
Type 2 Excludes
Not included here, the excluded code is not part of S82, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- 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
