About S22.2

S22.2 is the ICD-10-CM diagnosis code for fracture of sternum. It belongs to category S22 (fracture of rib(s), sternum and thoracic spine), block S20-S29 (injuries to the thorax) 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 5 subcodes must be used instead.

Within S22 (fracture of rib(s), sternum and thoracic spine), S22.2 is specifically for fracture of sternum. Related codes cover fracture of thoracic vertebra (S22.0), fracture of one rib (S22.3), multiple fractures of ribs (S22.4), Flail chest (S22.5) and fracture of bony thorax, part unspecified (S22.9).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open 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 and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Code first: , if applicable, spinal cord injury (S24.0-, S24.1-).

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