About S22.021

S22.021 is the ICD-10-CM diagnosis code for stable burst fracture of second thoracic vertebra. 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 6 subcodes must be used instead.

Within S22.02 (fracture of second thoracic vertebra), S22.021 is specifically for stable burst fracture of second thoracic vertebra. Related codes cover wedge compression fracture of second thoracic vertebra (S22.020), unstable burst fracture of second thoracic vertebra (S22.022), other fracture of second thoracic vertebra (S22.028) and unspecified fracture of second thoracic vertebra (S22.029).

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.
