About S52.211

S52.211 is the ICD-10-CM diagnosis code for Greenstick fracture of shaft of right 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 S52.21 (Greenstick fracture of shaft of ulna), S52.211 is specifically for Greenstick fracture of shaft of right ulna. Related codes cover left ulna (S52.212) and unspecified ulna (S52.219).

Codes in this range require a 7th character: A for initial encounter for closed fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion, P for subsequent encounter for fracture with malunion and S for sequela. 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.
