About S82.4

S82.4 is the ICD-10-CM diagnosis code for fracture of shaft of fibula. It belongs to category S82 (fracture of lower leg, including ankle), block S80-S89 (injuries to the knee and lower leg) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within S82 (fracture of lower leg, including ankle), S82.4 is specifically for fracture of shaft of fibula. Related codes cover fracture of patella (S82.0), fracture of upper end of tibia (S82.1), fracture of shaft of tibia (S82.2), fracture of lower end of tibia (S82.3), fracture of medial malleolus (S82.5), fracture of lateral malleolus (S82.6), other fractures of lower leg (S82.8) and unspecified fracture of lower leg (S82.9).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture type I or II, C for initial encounter for open fracture type IIIA, IIIB, or IIIC, D for subsequent encounter for closed fracture with routine healing, E for subsequent encounter for open fracture type I or II with routine healing, F for subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing and 10 more. Use placeholder "X" characters to fill any empty positions before the 7th character.

The conditions in its Excludes2 note aren't part of S82.4, but may be coded alongside it if the patient has both: fracture of lateral malleolus alone (S82.6-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

› From S82 Fracture of lower leg, including ankle
Note
  • 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
Includes
  • fracture of malleolus
Excludes1
  • traumatic amputation of lower leg (S88.-)
Excludes2
  • fracture of foot, except ankle (S92.-)
  • periprosthetic fracture around internal prosthetic ankle joint (M97.2)
