T42.6X4A is a billable diagnosis code used to specify a medical diagnosis of poisoning by other antiepileptic and sedative-hypnotic drugs, undetermined, 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.
T42.6X4A 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 other antiepileptic and sedative-hypnotic drugs undetermined. 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
Bromine
a halogen with the atomic symbol br, atomic number 35, and atomic weight 79.904. it is a volatile reddish-brown liquid that gives off suffocating vapors, is corrosive to the skin, and may cause severe gastroenteritis if ingested.Bromine Compounds
inorganic compounds that contain bromine as an integral part of the molecule.Bromine Radioisotopes
unstable isotopes of bromine that decay or disintegrate emitting radiation. br atoms with atomic weights 74-78, 80, and 82-90 are radioactive bromine isotopes.Bromisovalum
a sedative and mild hypnotic with potentially toxic effects.Chlormethiazole
a sedative and anticonvulsant often used in the treatment of alcohol withdrawal. chlormethiazole has also been proposed as a neuroprotective agent. the mechanism of its therapeutic activity is not entirely clear, but it does potentiate gamma-aminobutyric acid receptors response and it may also affect glycine receptors.Chlormezanone
a non-benzodiazepine that is used in the management of anxiety. it has been suggested for use in the treatment of muscle spasm.Ethchlorvynol
a sedative and hypnotic that has been used in the short-term management of insomnia. its use has been superseded by other drugs.Glutethimide
a hypnotic and sedative. its use has been largely superseded by other drugs.Paraldehyde
a hypnotic and sedative with anticonvulsant effects. however, because of the hazards associated with its administration, its tendency to react with plastic, and the risks associated with its deterioration, it has largely been superseded by other agents. it is still occasionally used to control status epilepticus resistant to conventional treatment. (from martindale, the extra pharmacopoeia, 30th ed, p608-9)Primidone
a barbiturate derivative that acts as a gaba modulator and anti-epileptic agent. it is partly metabolized to phenobarbital in the body and owes some of its actions to this metabolite.Dipsacales
an order of dicotyledonous flowering plants which includes six families. it is best known for its ornamental plants such as lonicera (honeysuckle), viburnum (arrowwood and guelder rose), and scabiosa (scabious, or pincushion flower).Valerian
a plant genus of the family valerianaceae, order dipsacales, subclass asteridae, class magnoliopsida. it is best known for the sedative use and valepotriate content of the roots. it is sometimes called garden heliotrope but is unrelated to true heliotrope (heliotropium).Valerianaceae
the valerian plant family of the order dipsacales, subclass asteridae, class magnoliopsida that is characterized by 3-5-lobed tubular flowers, often spurred at the base and clustered in tight heads.Valerianella
a plant genus of the family valerianaceae. it is sometimes called goosefoot cornsalad but should not be confused with true goosefoot (chenopodium).Valproic Acid
a fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of epilepsy and bipolar disorder. the mechanisms of its therapeutic actions are not well understood. it may act by increasing gamma-aminobutyric acid levels in the brain or by altering the properties of voltage-gated sodium channels.Vigabatrin
an analogue of gamma-aminobutyric acid. it is an irreversible inhibitor of 4-aminobutyrate transaminase, the enzyme responsible for the catabolism of gamma-aminobutyric acid and is used as an anticonvulsant. (from martindale the extra pharmacopoeia, 31st ed)Zolpidem
an imidazopyridine derivative and short-acting gaba-a receptor agonist that is used for the treatment of insomnia.
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 antiepileptic, sedative- hypnotic and antiparkinsonism drugs (T42). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Table of Drugs and Chemicals
The parent code T42.6X4 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.
