Poisoning by other general anesthetics, assault, sequela

This code indicates a long-term health condition or complication resulting from an intentional overdose or harmful exposure to a general anesthetic agent, inflicted by another person. The initial poisoning event occurred in the past, and the patient is now presenting with residual effects directly attributable to that assault.

Use this code when documenting a sequela (e.g., chronic neurological damage, organ dysfunction) that is a direct consequence of a past assault involving a general anesthetic. This applies to follow-up encounters for conditions that developed after the acute poisoning episode has resolved.

• Always assign an additional code(s) to specify the exact nature of the sequela (e.g., G93.1 for anoxic brain damage).
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character "A" for initial encounter.
• Ensure documentation clearly links the current condition to a past assault involving a general anesthetic.
