Poisoning by unspecified anesthetic, assault, sequela

This code signifies a long-term or late-occurring health problem resulting from a poisoning event involving an unspecified anesthetic agent, where the poisoning was intentionally inflicted by another person. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a patient presenting with a chronic condition or permanent damage directly attributable to a past assault involving an unknown anesthetic. This is appropriate for follow-up encounters addressing the lasting sequelae, not the initial acute poisoning. Examples include persistent neurological deficits or organ damage from a historical poisoning incident.

• Always use a seventh character of 'S' for sequela when the acute phase of the poisoning has concluded.
• Ensure documentation clearly links the current condition to a past poisoning by an unspecified anesthetic and specifies the assault intent.
• Code any specific manifestations of the sequela (e.g., specific neurological deficits) in addition to this code.
