T47.6X1S Poisoning by antidiarrheal drugs, accidental (unintentional), sequela

ICD-10-CM T47.6X1S: Poisoning by antidiarrheal drugs, accidental (unintentional), sequela

ICD-10-CM code T47.6X1S represents poisoning by antidiarrheal drugs, accidental (unintentional), sequela. This code appears in payer billing and coding materials, including a Medicare article for head imaging. The available public sources confirm the code descriptor but do not provide clinical details, documentation rules, or coverage guarantees for this specific diagnosis. 3 4

Plain-language overview

The official descriptor for T47.6X1S is poisoning by antidiarrheal drugs, accidental (unintentional), sequela. This label identifies a diagnosis code rather than providing clinical treatment guidance or personalized medical advice for a patient's specific condition. 3 4

What this code represents

The code T47.6X1S is listed alongside other diagnosis codes in a Medicare billing and coding article for CT of the head. The article includes the code descriptor but does not explicitly define the clinical parameters of the seventh character S. 3

A commercial payer policy document includes T47.6X1S within a broader list of diagnosis codes for head and neck imaging. This listing confirms the code's official descriptor but does not establish payer-specific coverage criteria or utilization rules. 4

Documentation considerations

The Medicare billing article and the commercial payer policy list T47.6X1S as a valid diagnosis code. Neither source explicitly outlines documentation elements required to support the use of the accidental intent or sequela character for this specific condition. 3 4

Coverage and utilization context

The Medicare article titled Billing and Coding: CT of the Head includes T47.6X1S in its content. The inclusion of this diagnosis code in a billing article does not explicitly state that the code guarantees coverage for any specific service. 3

What the sources add

The Medicare article and the commercial payer policy both list T47.6X1S with the identical descriptor of poisoning by antidiarrheal drugs, accidental (unintentional), sequela. This comparison shows the code appears across multiple payer contexts for imaging utilization. 3 4

Clinical context

A toxicology abstract notes that pediatric ingestions of methanol and ethylene glycol are accidental and unintentional. This source does not mention antidiarrheal drugs or the T47.6X1S diagnosis code. 1
