S82.466 — Nondisplaced segmental fracture of shaft of unspecified fibula
S82.466 is a non-billable header ICD-10-CM code for nondisplaced segmental fracture of shaft of unspecified fibula. 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
- R
- subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
- S
- sequela
Excludes1 inherited from the categories above S82.466
These are not written on S82.466, but they bind it: a note on a category applies to every code beneath it. Billing S82.466 with anything listed here is a denial.
Excludes2 inherited from the categories above S82.466
Also inherited, and the opposite of Excludes1: these conditions are not part of S82.466, but a patient can have both, so you may code both.
Other codes that can never be billed with S82.466
These codes carry an Excludes1 note pointing at S82.466. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S82.466 alone.
Risk adjustment
S82.466 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
S82.466 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about S82.466
- Is S82.466 a billable ICD-10-CM code?
- No. S82.466 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does S82.466 sit in the tabular list?
- Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the knee and lower leg (S80-S89).
- What cannot be coded together with S82.466?
- S82.466 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above S82.466 (S82) and apply to it just the same.
