Shock due to anesthesia, not elsewhere classified

This code signifies a state of acute circulatory failure resulting from an adverse reaction to an anesthetic agent, not attributable to other specific causes. It represents a life-threatening condition characterized by inadequate tissue perfusion and oxygen delivery, directly induced by anesthesia.

Apply this code when documentation clearly indicates shock as a direct consequence of anesthesia administration, and no other specific cause (e.g., anaphylaxis, hemorrhage) is identified. Supporting documentation should detail the anesthetic agent used, the onset of shock symptoms during or immediately after anesthesia, and the exclusion of other etiologies.

• Always sequence this code after the code for the adverse effect of the anesthetic agent (E-code).
• Differentiate from anaphylactic shock (995.0) or other forms of shock (e.g., hypovolemic, septic) where the primary cause is not the anesthetic itself.
• Ensure physician documentation explicitly links the shock to the anesthesia and rules out other potential causes.
