T40.992 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 other psychodysleptics [hallucinogens], intentional self-harm. 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 other psychodysleptics, intentional self-harm
Non-specific codes like T40.992 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 other psychodysleptics, intentional self-harm:

Clinical Information
Mescaline
hallucinogenic alkaloid isolated from the flowering heads (peyote) of lophophora (formerly anhalonium) williamsii, a mexican cactus used in indian religious rites and as an experimental psychotomimetic. among its cellular effects are agonist actions at some types of serotonin receptors. it has no accepted therapeutic uses although it is legal for religious use by members of the native american church.Phencyclidine
a hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. phencyclidine is similar to ketamine in structure and in many of its effects. like ketamine, it can produce a dissociative state. it exerts its pharmacological action through inhibition of nmda receptors (receptors, n-methyl-d-aspartate). as a drug of abuse, it is known as pcp and angel dust.Phencyclidine Abuse
the misuse of phencyclidine with associated psychological symptoms and impairment in social or occupational functioning.Receptors, Phencyclidine
specific sites or molecular structures on cell membranes or in cells with which phencyclidine reacts or to which it binds to elicit the specific response of the cell to phencyclidine. studies have demonstrated the presence of multiple receptor sites for pcp. these are the pcp/sigma site, which binds both pcp and psychotomimetic opiates but not certain antipsychotics, and the pcp site, which selectively binds pcp analogs.Psilocybin
the major of two hallucinogenic components of teonanacatl, the sacred mushroom of mexico, the other component being psilocin. (from merck index, 11th ed)
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
Poisoning
A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:
- Prescription or over-the-counter medicines taken in doses that are too high
- Overdoses of illegal drugs
- Carbon monoxide from gas appliances
- Household products, such as laundry powder or furniture polish
- Pesticides
- Indoor or outdoor plants
- Metals such as lead and mercury
The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison.
