About S24

S24 is the ICD-10-CM diagnosis code for injury of nerves and spinal cord at thorax level. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S24.0 (cord), S24.1 (cord), S24.2 (spine), S24.3 (thorax), S24.4 (system), S24.8 (thorax) and S24.9 (thorax).

The conditions in its Excludes2 note aren't part of S24, but may be coded alongside it if the patient has both: injury of brachial plexus (S14.3).

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