Shock due to anesthesia, subsequent encounter

This code signifies a state of circulatory collapse resulting from an adverse reaction to an anesthetic agent, occurring during a follow-up visit or subsequent period of care. It indicates that the patient is experiencing the ongoing effects or complications of anesthesia-induced shock, rather than the initial acute event.

Apply this code when a patient presents for follow-up care, such as an office visit or readmission, and is still being treated for or monitored due to shock that was definitively caused by anesthesia. This includes situations where the initial shock has resolved but residual symptoms or complications are being managed.

• Always sequence this code after the primary diagnosis indicating the reason for the subsequent encounter.
• Ensure documentation clearly links the shock to anesthesia and specifies that this is not the initial presentation.
• Verify the "D" seventh character is appropriate for a subsequent encounter, indicating ongoing care for the condition.
