About coding sternum fracture
The ICD-10-CM code for sternum fracture is S22.20 (Unspecified fracture of sternum). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S22.20.
Within S22.2, choose S22.20 (Unspecified fracture of sternum) only when documentation doesn't support a more specific option: fracture of manubrium (S22.21), fracture of body of sternum (S22.22), sternal manubrial dissociation (S22.23) and fracture of xiphoid process (S22.24).
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-).
