Poisn by antidotes and chelating agents, assault, sequela

This code signifies a long-term health problem or complication resulting from an intentional poisoning by an antidote or chelating agent. It indicates that the original act of poisoning was an assault, and the patient is now experiencing residual effects.

Apply this code when documenting a patient presenting with a chronic condition or permanent injury directly attributable to a past assault involving an antidote or chelating agent. This would be used for follow-up care related to the sequelae, not the initial acute poisoning event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past poisoning by an antidote/chelating agent and specifies the assault intent.
• Do not use for acute poisoning events; this is exclusively for residual effects.
