  • BILLABLE CODE - Use T81.10XA for initial encounter

  • BILLABLE CODE - Use T81.10XS for sequela
  • NON-BILLABLE CODE - T81.11 for Postprocedural cardiogenic shock
  • BILLABLE CODE - Use T81.11XA for initial encounter
  • BILLABLE CODE - Use T81.11XD for subsequent encounter
  • BILLABLE CODE - Use T81.11XS for sequela
  • NON-BILLABLE CODE - T81.12 for Postprocedural septic shock
  • BILLABLE CODE - Use T81.12XA for initial encounter

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code T81.1:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients


Shock happens when not enough blood and oxygen can get to your organs and tissues. It causes very low blood pressure and may be life-threatening. It often happens along with a serious injury.

There are several kinds of shock. Hypovolemic shock happens when you lose a lot of blood or fluids. Causes include internal or external bleeding, dehydration, burns, and severe vomiting and/or diarrhea. Septic shock is caused by infections in the bloodstream. A severe allergic reaction can cause anaphylactic shock. An insect bite or sting might cause it. Cardiogenic shock happens when the heart cannot pump blood effectively. This may happen after a heart attack. Neurogenic shock is caused by damage to the nervous system.

Symptoms of shock include

Shock is a life-threatening medical emergency and it is important to get help right away. Treatment of shock depends on the cause.
