Poisoning by mixed antiepileptics, self-harm, sequela

This code signifies the long-term effects or complications arising from a deliberate overdose of multiple antiepileptic medications. It indicates that the patient intentionally ingested a combination of these drugs, and the current encounter addresses a condition directly resulting from that past event.

Apply this code when documenting conditions such as chronic organ damage, neurological deficits, or persistent psychiatric issues that are directly attributable to a previous intentional self-poisoning involving mixed antiepileptics. This code is appropriate for follow-up care or treatment of sequelae, not the acute poisoning event itself.

• 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 mixed antiepileptic poisoning.
• Do not use this code for acute poisoning; instead, refer to the appropriate acute poisoning codes (e.g., T42.5X2A).
