Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of narcotics and psychodysleptics [hallucinogens]
        (T40)

T40.5X3 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by cocaine, assault. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Poisoning by cocaine, assault

Non-specific codes like T40.5X3 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for poisoning by cocaine, assault:

  • Use T40.5X3A for initial encounter - BILLABLE CODE

  • Use T40.5X3D for subsequent encounter - BILLABLE CODE

  • Use T40.5X3S for sequela - BILLABLE CODE

Clinical Information

  • Cocaine

    an alkaloid ester extracted from the leaves of plants including coca. it is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. it also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
  • Cocaine Smoking

    smoking of cocaine.
  • Cocaine-Related Disorders

    disorders related or resulting from use of cocaine.
  • Crack Cocaine

    the purified, alkaloidal, extra-potent form of cocaine. it is smoked (free-based), injected intravenously, and orally ingested. use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. the slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.

Coding Guidelines

When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of narcotics and psychodysleptics [hallucinogens] (T40). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Table of Drugs and Chemicals

The code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Patient Education


Cocaine

Cocaine is a white powder. It can be snorted up the nose or mixed with water and injected with a needle. Cocaine can also be made into small white rocks, called crack. Crack is smoked in a small glass pipe.

Cocaine speeds up your whole body. You may feel full of energy, happy, and excited. But then your mood can change. You can become angry, nervous, and afraid that someone's out to get you. You might do things that make no sense. After the "high" of the cocaine wears off, you can "crash" and feel tired and sad for days. You also get a strong craving to take the drug again to try to feel better.

No matter how cocaine is taken, it is dangerous. Some of the most common serious problems include heart attack and stroke. You are also at risk for HIV/AIDS and hepatitis, from sharing needles or having unsafe sex. Cocaine is more dangerous when combined with other drugs or alcohol.

It is easy to lose control over cocaine use and become addicted. Then, even if you get treatment, it can be hard to stay off the drug. People who stopped using cocaine can still feel strong cravings for the drug, sometimes even years later.
