About coding interscapular region contusion

The ICD-10-CM code for interscapular region contusion is S20.229 (Contusion of unspecified back wall of thorax).

Within S20.22, choose S20.229 (unspecified back wall of thorax) only when documentation doesn't support a more specific option: right back wall of thorax (S20.221), left back wall of thorax (S20.222), bilateral back wall of thorax (S20.223) and middle back wall of thorax (S20.224).

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.
