S82.454C — Nondisplaced comminuted fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
S82.454C is a billable, specific ICD-10-CM code for nondisplaced comminuted fracture of shaft of right fibula, initial encounter for open fracture type iiia, iiib, or iiic. It is valid for submission on a claim.
7th character "C" — initial encounter for open fracture type IIIA, IIIB, or IIIC
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

Excludes1 inherited from the categories above S82.454C
These are not written on S82.454C, but they bind it: a note on a category applies to every code beneath it. Billing S82.454C with anything listed here is a denial.
Excludes2 inherited from the categories above S82.454C
Also inherited, and the opposite of Excludes1: these conditions are not part of S82.454C, but a patient can have both, so you may code both.
Other codes that can never be billed with S82.454C
These codes carry an Excludes1 note pointing at S82.454C. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S82.454C alone.
Risk adjustment
S82.454C 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.
Medicare coverage
S82.454C is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
