ICD-10: T40.5X3

ICD-10 code T40.5X3 refers specifically to "Poisoning by cocaine, assault, subsequent encounter." This code is part of the broader T40 category, which encompasses various types of drug poisoning, including those caused by cocaine. Below is a detailed clinical description and relevant information regarding this diagnosis code.

Clinical Description

Definition

The T40.5X3 code is used to classify cases where an individual has experienced poisoning due to cocaine, specifically in the context of an assault. The designation "subsequent encounter" indicates that this is not the initial visit for treatment related to the poisoning; rather, it is a follow-up visit after the initial encounter.

Clinical Presentation

Patients with cocaine poisoning may present with a range of symptoms, which can vary based on the amount ingested and the method of use (e.g., snorting, injecting, or smoking). Common symptoms include:

• Cardiovascular Effects: Increased heart rate (tachycardia), elevated blood pressure (hypertension), and potential arrhythmias.
• Neurological Symptoms: Agitation, anxiety, hallucinations, seizures, and altered mental status.
• Gastrointestinal Issues: Nausea, vomiting, and abdominal pain.
• Respiratory Distress: Difficulty breathing or respiratory failure in severe cases.

Etiology

Cocaine is a powerful stimulant that affects the central nervous system. In cases of assault, the poisoning may occur through forced ingestion or injection, leading to acute toxicity. The context of assault adds a layer of complexity, as it may involve legal considerations and the need for protective services for the victim.

Coding Details

Code Structure

• T40.5: This is the base code for "Poisoning by cocaine."
• X3: The additional character indicates that the poisoning was a result of an assault and that this is a subsequent encounter.

Usage Guidelines

• Subsequent Encounter: This code should be used when the patient is returning for follow-up care after the initial treatment for cocaine poisoning. It is essential to document the patient's progress and any ongoing symptoms or complications.
• Documentation: Accurate documentation is crucial for coding purposes. Healthcare providers should ensure that the circumstances of the poisoning (i.e., assault) are clearly noted in the medical record.
