S52.26Segmental fracture of shaft of ulna

S52.26 is the ICD-10-CM diagnosis code for segmental fracture of shaft of ulna. It belongs to category S52 (fracture of forearm), block S50-S59 (injuries to the elbow and forearm) 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 S52.2 (fracture of shaft of ulna), S52.26 is specifically for segmental fracture of shaft of ulna. Related codes cover unspecified fracture of shaft of ulna (S52.20), Greenstick fracture of shaft of ulna (S52.21), transverse fracture of shaft of ulna (S52.22), oblique fracture of shaft of ulna (S52.23), spiral fracture of shaft of ulna (S52.24), comminuted fracture of shaft of ulna (S52.25), Monteggia's fracture of ulna (S52.27), Bent bone of ulna (S52.28) and 1 more.

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.
