S82.45Comminuted fracture of shaft of fibula

S82.45 is the ICD-10-CM diagnosis code for comminuted 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 6 subcodes must be used instead.

Within S82.4 (fracture of shaft of fibula), S82.45 is specifically for comminuted fracture of shaft of fibula. Related codes cover unspecified fracture of shaft of fibula (S82.40), transverse fracture of shaft of fibula (S82.42), oblique fracture of shaft of fibula (S82.43), spiral fracture of shaft of fibula (S82.44), segmental fracture of shaft of fibula (S82.46) and other fracture of shaft of fibula (S82.49).

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.

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