About S24.13

S24.13 is the ICD-10-CM diagnosis code for anterior cord syndrome of thoracic spinal cord. It belongs to category S24 (injury of nerves and spinal cord at thorax level), 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 5 subcodes must be used instead.

Within S24.1 (other and unspecified injuries of thoracic spinal cord), S24.13 is specifically for anterior cord syndrome of thoracic spinal cord. Related codes cover unspecified injury of thoracic spinal cord (S24.10), complete lesion of thoracic spinal cord (S24.11), Brown-Sequard syndrome of thoracic spinal cord (S24.14) and other incomplete lesions of thoracic spinal cord (S24.15).

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.
