ICD-10 code for forearm fracture

The ICD-10-CM code for forearm fracture is S52.9 (Unspecified fracture of forearm).

Within S52, choose S52.9 (Unspecified fracture of forearm) only when documentation doesn't support a more specific option: fracture of upper end of ulna (S52.0), fracture of upper end of radius (S52.1), fracture of shaft of ulna (S52.2), fracture of shaft of radius (S52.3), fracture of lower end of radius (S52.5) and fracture of lower end of ulna (S52.6).

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.
