Poisoning by expectorants, undetermined, sequela

This code signifies the long-term or residual effects resulting from an unconfirmed or unknown intent of poisoning by an expectorant medication. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to the past exposure. The "undetermined" nature means the intent (e.g., accidental, intentional self-harm, assault) could not be established.

Use this code when documenting a patient presenting with chronic or persistent symptoms, conditions, or complications that are clearly linked to a past poisoning by an expectorant, and the original intent of the poisoning was not determined or documented. This applies to follow-up encounters for ongoing management of sequelae, not the initial acute poisoning event.

• Always assign an additional code(s) to specify the particular sequela or residual condition being treated.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code with the 7th character "A" for initial encounter.
• Ensure documentation clearly supports the causal link between the past expectorant poisoning and the current sequela, as well as the undetermined intent.
