About T81.12

T81.12 is the ICD-10-CM diagnosis code for postprocedural septic shock. It belongs to category T81 (complications of procedures, not elsewhere classified), block T80-T88 (complications of surgical and medical care, not elsewhere classified) 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 T81.1 (postprocedural shock), T81.12 is specifically for postprocedural septic shock. Related codes cover unspecified (T81.10), postprocedural cardiogenic shock (T81.11) and other postprocedural shock (T81.19).

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.

Code first: underlying infection.

Use an additional code, to identify any associated acute organ dysfunction, if applicable. Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

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

7th character

The appropriate 7th character is to be added to each code from category T81
