T79.4Traumatic shock

T79.4 is the ICD-10-CM diagnosis code for traumatic shock. It belongs to category T79 (certain early complications of trauma, not elsewhere classified), block T79 (certain early complications of trauma) 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 T79 (certain early complications of trauma, not elsewhere classified), T79.4 is specifically for traumatic shock. Related codes cover air embolism (traumatic) (T79.0), fat embolism (traumatic) (T79.1), traumatic secondary and recurrent hemorrhage and seroma (T79.2), traumatic anuria (T79.5), traumatic ischemia of muscle (T79.6), traumatic subcutaneous emphysema (T79.7), other early complications of trauma (T79.8), unspecified early complication of trauma (T79.9) and 1 more.

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.

Don't report T79.4 together with the conditions in its Excludes1 note: anaphylactic shock due to adverse food reaction (T78.0-), anaphylactic shock due to correct medicinal substance properly administered (T88.6), anaphylactic shock due to serum (T80.5-), anaphylactic shock NOS (T78.2) and 9 more.

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