S82.466D Nondisplaced segmental fracture of shaft of unspecified fibula, subsequent encounter for closed fracture with routine healing

Billable ICD-10-CM code, FY2026.

Built from S82.466 with 7th character D (subsequent encounter for closed fracture with routine healing).

Applies from S82 Fracture of lower leg, including ankle

Includes

• fracture of malleolus

Excludes1 (never code together)

• traumatic amputation of lower leg (S88.-)

Excludes2 (not included here)

• 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-)

7th character note

• The appropriate 7th character is to be added to all codes from category S82

Notes

• 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

7th character required

• 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

Applies from S82.4 Fracture of shaft of fibula

Excludes2 (not included here)

• fracture of lateral malleolus alone (S82.6-)
