2025 ICD-10-CM code T40.5
Poisoning by, adverse effect of and underdosing of cocaine.
Modifiers may apply to indicate the episode of care or other specific circumstances.
Medical necessity must be established based on the specific scenario. For poisoning or adverse effects, the need for treatment is generally evident. For underdosing, the impact of the insufficient dosage on the patient's condition needs to be documented.
In simple words: This code indicates a health issue related to cocaine, including overdose, negative side effects, or taking too little.
This code represents poisoning by, adverse effect of, and underdosing of cocaine.
Example 1: A patient presents to the emergency department with symptoms of cocaine overdose., A patient experiences cardiac arrhythmia as an adverse effect of cocaine use., A patient on a prescribed cocaine-based medication (for a specific medical procedure) inadvertently takes less than the instructed dose, leading to underdosing symptoms.
Documentation should clearly specify the circumstance: poisoning, adverse effect, or underdosing. Details of the incident, symptoms, and treatment provided should be recorded. If an adverse effect, describe the specific effect and link it to cocaine use. For underdosing, specify the prescribed dosage and amount taken.
