AHA Coding Clinic® for ICD-9 - 2011 Issue 4; VOLUMES 1 & 2 NEW/REVISED CODES
Postoperative Shock
Effective October 1, 2011, codes 998.00, Postoperative shock, unspecified; 998.01, Postoperative shock, cardiogenic; 998.02, Postoperative shock, septic; and 998.09, Postoperative shock, other, were created to describe specific types or mechanisms of postoperative shock. Shock is a physiologic state characterized by a decrease in the volume of blood that flows through the tissues causing a reduction in the amount of oxygen throughout the body. This reduction in oxygen may be a result of impaired binding of oxygen molecules to hemoglobin or the decrease in circulation of oxygenated blood. The effects of the imbalance between oxygen delivery...

Article Overview
This article reviews postoperative shock from a coding and clinical documentation perspective. It covers the broad clinical types of shock seen after procedures, discusses the 2011 creation of more specific postoperative shock diagnosis codes, and references related guidance on postoperative complications and associated coding context. It is useful for coders, CDI professionals, and revenue cycle staff working with postoperative complication documentation.
Why This Topic Matters
Postoperative shock can affect diagnosis reporting, complication capture, and the interpretation of postoperative documentation. Understanding the scope of the topic helps coding professionals recognize when the chart language may align with a more specific postoperative complication category and related associated conditions.
