Poisoning by antipruritics, intentional self-harm, sequela

This code indicates a long-term complication or residual effect stemming from a deliberate act of self-poisoning involving an antipruritic medication. It signifies that the acute phase of the poisoning has passed, but the patient continues to experience health issues directly attributable to that event. These sequelae could range from organ damage to neurological deficits.

Apply this code when documenting a patient presenting with chronic or residual conditions that are a direct consequence of a past intentional self-harm overdose of an antipruritic agent. This is appropriate for follow-up visits or when the long-term effects are being managed, and the acute poisoning event is no longer the primary focus of care. It should not be used for the initial acute poisoning encounter.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional antipruritic poisoning.
• Verify that the poisoning was indeed due to an antipruritic and not another class of medication.
