Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of other systemic anti-infectives and antiparasitics
        (T37)

T37.4X1 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 anthelminthics, accidental (unintentional). 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 anthelminthics, accidental (unintentional)

Non-specific codes like T37.4X1 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 anthelminthics, accidental (unintentional):

  • Use T37.4X1A for initial encounter - BILLABLE CODE

  • Use T37.4X1D for subsequent encounter - BILLABLE CODE

  • Use T37.4X1S for sequela - BILLABLE CODE

Clinical Information

  • Albendazole

    a benzimidazole broad-spectrum anthelmintic structurally related to mebendazole that is effective against many diseases. (from martindale, the extra pharmacopoeia, 30th ed, p38)

    a species of the chenopodium genus which is the source of edible seed called quinoa. it contains makisterone a and other steroids, some having ecdysteroid activity on insects.
  • 2,6-Dichloroindophenol

    a dye used as a reagent in the determination of vitamin c.
  • Dichlorophen

    nontoxic laxative vermicide effective for taenia infestation. it tends to produce colic and nausea. it is also used as a veterinary fungicide, anthelmintic, and antiprotozoan. (from merck, 11th ed.)
  • Diethylcarbamazine

    an anthelmintic used primarily as the citrate in the treatment of filariasis, particularly infestations with wucheria bancrofti or loa loa.
  • Fenbendazole

    antinematodal benzimidazole used in veterinary medicine.
  • Ivermectin

    a mixture of mostly avermectin h2b1a (rn 71827-03-7) with some avermectin h2b1b (rn 70209-81-3), which are macrolides from streptomyces avermitilis. it binds glutamate-gated chloride channel to cause increased permeability and hyperpolarization of nerve and muscle cells. it also interacts with other chloride channels. it is a broad spectrum antiparasitic that is active against microfilariae of onchocerca volvulus but not the adult form.
  • Levamisole

    an antihelminthic drug that has been tried experimentally in rheumatic disorders where it apparently restores the immune response by increasing macrophage chemotaxis and t-lymphocyte function. paradoxically, this immune enhancement appears to be beneficial in rheumatoid arthritis where dermatitis, leukopenia, and thrombocytopenia, and nausea and vomiting have been reported as side effects. (from smith and reynard, textbook of pharmacology, 1991, p435-6)
  • Lucanthone

    one of the schistosomicides, it has been replaced largely by hycanthone and more recently praziquantel. (from martindale the extrapharmacopoeia, 30th ed., p46)
  • Mebendazole

    a benzimidazole that acts by interfering with carbohydrate metabolism and inhibiting polymerization of microtubules.
  • Niclosamide

    an antihelmintic that is active against most tapeworms. (from martindale, the extra pharmacopoeia, 30th ed, p48)
  • Niridazole

    an antischistosomal agent that has become obsolete.
  • Oxamniquine

    an anthelmintic with schistosomicidal activity against schistosoma mansoni, but not against other schistosoma spp. oxamniquine causes worms to shift from the mesenteric veins to the liver where the male worms are retained; the female worms return to the mesentery, but can no longer release eggs. (from martindale, the extra pharmacopoeia, 31st ed, p121)
  • Diketopiperazines

    piperazines with two keto oxygens.
  • Piperazine

    an anti-nematodal agent effective against the intestinal nematodes ascaris lumbricoides (roundworm) and enterobius vermicularis (pinworm, threadworm). it produces a neuromuscular block leading to flaccid muscle paralysis in susceptible worms, which are then dislodged from the gut and expelled in feces.
  • Piperazines

    compounds that are derived from piperazine.
  • Praziquantel

    an anthelmintic used in most schistosome and many cestode infestations.
  • Pyrantel

    a depolarizing neuromuscular-blocking agent, that causes persistent nicotinic activation resulting in spastic paralysis of susceptible nematodes. it is a drug of second-choice after benzimidazoles for treatment of ascariasis, hookworm, and pinworm infections, being effective after a single dose. (from smith and reynard, textbook of pharmacology, 1992, p920)

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 other systemic anti-infectives and antiparasitics (T37). 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 Terms
These 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.
  • Poisoning by anthelminthics NOS

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.

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?
