About coding ulna shaft fracture
The ICD-10-CM code for ulna shaft fracture is S52.20 (Unspecified fracture of shaft of ulna). The official index lists 36 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S52.20.
Within S52.2, choose S52.20 (Unspecified fracture of shaft of ulna) only when documentation doesn't support a more specific option: 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), segmental fracture of shaft of ulna (S52.26), 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.
