2024 ICD-10-CM Diagnosis Code T43.4X2

Specific Coding Applicable to Poisoning by butyrophen/thiothixen neuroleptics, self-harm

Non-specific codes like T43.4X2 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 butyrophen/thiothixen neuroleptics, self-harm:

Clinical Information

• Benperidol

  a butyrophenone with general properties similar to those of haloperidol. it has been used in the treatment of aberrant sexual behavior. (from martindale, the extra pharmacopoeia, 30th ed, p567)

• Chlorprothixene

  a thioxanthine with effects similar to the phenothiazine antipsychotics.

• Clopenthixol

  a thioxanthene with therapeutic actions similar to the phenothiazine antipsychotics. it is an antagonist at d1 and d2 dopamine receptors.

• Flupenthixol

  a thioxanthene neuroleptic that, unlike chlorpromazine, is claimed to have cns-activating properties. it is used in the treatment of psychoses although not in excited or manic patients. (from martindale, the extra pharmacopoeia, 30th ed, p595)

• Haloperidol

  a phenyl-piperidinyl-butyrophenone that is used primarily to treat schizophrenia and other psychoses. it is also used in schizoaffective disorder, delusional disorders, ballism, and tourette syndrome (a drug of choice) and occasionally as adjunctive therapy in intellectual disability and the chorea of huntington disease. it is a potent antiemetic and is used in the treatment of intractable hiccups. (from ama drug evaluations annual, 1994, p279)

• Spiperone

  a spiro butyrophenone analog similar to haloperidol and other related compounds. it has been recommended in the treatment of schizophrenia.

• Thiothixene

  a thioxanthine used as an antipsychotic agent. its effects are similar to the phenothiazine antipsychotics.

• Trifluperidol

  a butyrophenone with general properties similar to those of haloperidol. it is used in the treatment of psychoses including mania and schizophrenia. (from martindale, the extra pharmacopoeia, 30th ed, p621)

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

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. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.
