Clinical Information
Amisulpride
a benzamide derivative that is used as an antipsychotic agent for the treatment of schizophrenia. it is also used as an antidepressive agent.Buspirone
an anxiolytic agent and serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. its structure is unrelated to those of the benzodiazapines, but it has an efficacy comparable to diazepam.Droperidol
a butyrophenone with general properties similar to those of haloperidol. it is used in conjunction with an opioid analgesic such as fentanyl to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeon. it is also used as a premedicant, as an antiemetic, and for the control of agitation in acute psychoses. (from martindale, the extra pharmacopoeia, 29th ed, p593)Fluspirilene
a long-acting injectable antipsychotic agent used for chronic schizophrenia.Hydroxyzine
a histamine h1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. unlike its major metabolite cetirizine, it does cause drowsiness. it is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.Loxapine
an antipsychotic agent used in schizophrenia.Meprobamate
a carbamate with hypnotic, sedative, and some muscle relaxant properties, although in therapeutic doses reduction of anxiety rather than a direct effect may be responsible for muscle relaxation. meprobamate has been reported to have anticonvulsant actions against petit mal seizures, but not against grand mal seizures (which may be exacerbated). it is used in the treatment of anxiety disorders, and also for the short-term management of insomnia but has largely been superseded by the benzodiazepines. (from martindale, the extra pharmacopoeia, 30th ed, p603)Molindone
an indole derivative effective in schizophrenia and other psychoses and possibly useful in the treatment of the aggressive type of undersocialized conduct disorder. molindone has much lower affinity for d2 receptors than most antipsychotic agents and has a relatively low affinity for d1 receptors. it has only low to moderate affinity for cholinergic and alpha-adrenergic receptors. some electrophysiologic data from animals indicate that molindone has certain characteristics that resemble those of clozapine. (from ama drug evaluations annual, 1994, p283)Olanzapine
a benzodiazepine derivative that binds serotonin receptors; muscarinic receptors; histamine h1 receptors; adrenergic alpha-1 receptors; and dopamine receptors. it is an antipsychotic agent used in the treatment of schizophrenia; bipolar disorder; and major depressive disorder; it may also reduce nausea and vomiting in patients undergoing chemotherapy.Penfluridol
one of the long-acting antipsychotic agents used for maintenance or long-term therapy of schizophrenia and other psychotic disorders.Pimozide
a diphenylbutylpiperidine that is effective as an antipsychotic agent and as an alternative to haloperidol for the suppression of vocal and motor tics in patients with tourette syndrome. although the precise mechanism of action is unknown, blockade of postsynaptic dopamine receptors has been postulated. (from ama drug evaluations annual, 1994, p403)Raclopride
a substituted benzamide that has antipsychotic properties. it is a dopamine d2 receptor (see receptors, dopamine d2) antagonist.Remoxipride
an antipsychotic agent that is specific for dopamine d2 receptors. it has been shown to be effective in the treatment of schizophrenia.Sulpiride
a dopamine d2-receptor antagonist. it has been used therapeutically as an antidepressant, antipsychotic, and as a digestive aid. (from merck index, 11th ed)Tetrabenazine
a drug formerly used as an antipsychotic and treatment of various movement disorders. tetrabenazine blocks neurotransmitter uptake into adrenergic storage vesicles and has been used as a high affinity label for the vesicle transport system.
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 psychotropic drugs, not elsewhere classified (T43). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

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
Medication Errors
Medicines treat infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the health care provider's office, at the pharmacy, or at home. You can help prevent errors by:
- Knowing your medicines. When you get a prescription, ask the name of the medicine and check to make sure that the pharmacy gave you the right medicine. Make sure that you understand how often you should take the medicine and how long you should take it.
- Keeping a list of medicines.
- Write down all of the medicines that you are taking, including the names of your medicines, how much you take, and when you take them. Make sure to include any over-the-counter medicines, vitamins, supplements, and herbs that you take.
- List the medicines that you are allergic to or that have caused you problems in the past.
- Take this list with you every time you see a health care provider.
- Reading medicine labels and following the directions. Don't just rely on your memory - read the medication label every time. Be especially careful when giving medicines to children.
- Asking questions. If you don't know the answers to these questions, ask your health care provider or pharmacist:
- Why am I taking this medicine?
- What are the common side effects?
- What should I do if I have side effects?
- When should I stop this medicine?
- Can I take this medicine with the other medicines and supplements on my list?
- Do I need to avoid certain foods or alcohol while taking this medicine?
