About coding sternal region contusion
The ICD-10-CM code for sternal region contusion is S20.219 (Contusion of unspecified front wall of thorax).
Within S20.21, choose S20.219 (unspecified front wall of thorax) only when documentation doesn't support a more specific option: right front wall of thorax (S20.211), left front wall of thorax (S20.212), bilateral front wall of thorax (S20.213) and middle front wall of thorax (S20.214).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter 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.
