T43.3X2A is a billable diagnosis code used to specify a medical diagnosis of poisoning by phenothiazine antipsychotics and neuroleptics, intentional self-harm, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
T43.3X2A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like poisoning by phenothiazine antipsychotics and neuroleptics intentional self-harm. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Clinical Information
Acepromazine
a phenothiazine that is used in the treatment of psychoses.Chlorpromazine
the prototypical phenothiazine antipsychotic drug. like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking dopamine receptors. chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.Fluphenazine
a phenothiazine used in the treatment of psychoses. its properties and uses are generally similar to those of chlorpromazine.Mesoridazine
a phenothiazine antipsychotic with effects similar to chlorpromazine.Methotrimeprazine
a phenothiazine with pharmacological activity similar to that of both chlorpromazine and promethazine. it has the histamine-antagonist properties of the antihistamines together with central nervous system effects resembling those of chlorpromazine. (from martindale, the extra pharmacopoeia, 30th ed, p604)Perazine
a phenothiazine antipsychotic with actions and uses similar to those of chlorpromazine. extrapyramidal symptoms may be more common than other side effects.Perphenazine
an antipsychotic phenothiazine derivative with actions and uses similar to those of chlorpromazine.Prochlorperazine
a phenothiazine antipsychotic used principally in the treatment of nausea; vomiting; and vertigo. it is more likely than chlorpromazine to cause extrapyramidal disorders. (from martindale, the extra pharmacopoeia, 30th ed, p612)Promazine
a phenothiazine with actions similar to chlorpromazine but with less antipsychotic activity. it is primarily used in short-term treatment of disturbed behavior and as an antiemetic.Thiethylperazine
a dopamine antagonist that is particularly useful in treating the nausea and vomiting associated with anesthesia, mildly emetic cancer chemotherapy agents, radiation therapy, and toxins. this piperazine phenothiazine does not prevent vertigo or motion sickness. (from ama drug evaluations annual, 1994, p457)Thioridazine
a phenothiazine antipsychotic used in the management of phycoses, including schizophrenia.Trifluoperazine
a phenothiazine with actions similar to chlorpromazine. it is used as an antipsychotic and an antiemetic.Triflupromazine
a phenothiazine used as an antipsychotic agent and as an antiemetic.
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
Convert T43.3X2A to ICD-9-CM
- ICD-9-CM Code: 969.1 - Pois-phenothiazine tranq
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment. - ICD-9-CM Code: E950.3 - Poison-psychotropic agt
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
Table of Drugs and Chemicals
The parent code T43.3X2 of the current diagnosis 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.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
