About S29.8

S29.8 is the ICD-10-CM diagnosis code for other specified injuries of thorax. It belongs to category S29 (other and unspecified injuries of thorax), 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 3 subcodes must be used instead.

Within S29, choose S29.8 (Other specified injuries of thorax) only when documentation doesn't support a more specific option: injury of muscle and tendon at thorax level (S29.0) and unspecified injury of thorax (S29.9).

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.
