2025 ICD-10-CM code T46.2X1

Accidental poisoning by other antidysrhythmic drugs.

Always use an additional code from Chapter 20 to indicate the external cause of the poisoning. If the specific antidysrhythmic drug is known, use the most specific code available.If a retained foreign body is involved, use a Z18.- code.

Modifiers may be applicable depending on the specific circumstances of the poisoning and the services rendered.

Medical necessity is established by the presence of symptoms resulting from the accidental ingestion of the antidysrhythmic medication.Treatment is medically necessary to manage the life-threatening complications of the poisoning.

The clinical responsibility involves assessing the patient's condition, identifying the specific antidysrhythmic drug involved, providing supportive treatment to manage the effects of the poisoning, and monitoring the patient's vital signs and response to treatment.

IMPORTANT Consider additional codes from Chapter 20 (External causes of morbidity) to specify the cause of the poisoning.Codes T46.2X2 (intentional self-harm), T46.2X3 (assault), and T46.2X4 (undetermined) may be relevant depending on the circumstances.Also, use additional codes to identify any retained foreign body (Z18.-).

In simple words: This code means someone accidentally took too much of a heart rhythm medicine, causing a poisoning event.

This code classifies accidental (unintentional) poisoning due to other antidysrhythmic drugs, not otherwise specified.It's crucial to identify the specific drug involved for complete clinical documentation.This code should be used when the poisoning is unintentional and involves an antiarrhythmic medication not specifically listed elsewhere in the ICD-10-CM classification.

Example 1: A 70-year-old male patient with a history of atrial fibrillation is found unresponsive at home.Empty pill bottles containing an antiarrhythmic medication are found nearby.Laboratory tests reveal elevated drug levels.T46.2X1 is assigned., A 35-year-old female patient presents to the emergency department after accidentally ingesting her child's medication, which was an antiarrhythmic drug.Symptoms include nausea, vomiting, and dizziness.T46.2X1 is assigned., A 62-year-old male patient is admitted to the hospital after experiencing an overdose of an antiarrhythmic medication. The overdose was a result of an accidental ingestion due to an improper prescription label. The physician documents the case using T46.2X1 and appropriate external cause codes from Chapter 20.

Detailed documentation should include the name of the antidysrhythmic drug ingested, the amount ingested, the time of ingestion, the patient's symptoms, vital signs, laboratory findings, treatment provided, and the patient's response to treatment.Documentation should also specify whether the ingestion was accidental, intentional, or of undetermined intent.

** This code should not be used for adverse effects or underdosing; use the appropriate T46.2X codes for such cases.Always refer to the official ICD-10-CM guidelines for the most up-to-date coding information.
