About S29

S29 is the ICD-10-CM diagnosis code for other and unspecified injuries of thorax. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: S29.0 (level), S29.8 (thorax) and S29.9 (thorax).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
