S82.842 — Displaced bimalleolar fracture of left lower leg
S82.842 is a non-billable header ICD-10-CM code for displaced bimalleolar fracture of left lower leg. 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.
This code requires a 7th character
The appropriate 7th character is to be added to all codes from category S82
- A
- initial encounter for closed fracture
- B
- initial encounter for open fracture type I or II
- C
- initial encounter for open fracture type IIIA, IIIB, or IIIC
- D
- subsequent encounter for closed fracture with routine healing
- 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

Excludes1 inherited from the categories above S82.842
These are not written on S82.842, but they bind it: a note on a category applies to every code beneath it. Billing S82.842 with anything listed here is a denial.
Excludes2 inherited from the categories above S82.842
Also inherited, and the opposite of Excludes1: these conditions are not part of S82.842, but a patient can have both, so you may code both.
Other codes that can never be billed with S82.842
These codes carry an Excludes1 note pointing at S82.842. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S82.842 alone.
Risk adjustment
S82.842 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
S82.842 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
