- Code Navigator:
T37.4X4S is a billable diagnosis code used to specify a medical diagnosis of poisoning by anthelminthics, undetermined, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T37.4X4S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like poisoning by anthelminthics undetermined. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

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)Chenopodium
a plant genus in the chenopodiaceae family.Chenopodium album
a plant species in the chenopodium genus known for edible greens.Chenopodium ambrosioides
a plant species of the genus chenopodium known for toxicity to intestinal worms and other simple organisms.Chenopodium quinoa
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)Pyrantel Pamoate
broad spectrum antinematodal anthelmintic used also in veterinary medicine.Pyrantel Tartrate
broad spectrum anthelmintic for livestock.Santonin
anthelmintic isolated from the dried unexpanded flower heads of artemisia maritima and other species of artemisia found principally in russian and chinese turkestan and the southern ural region. (from merck, 11th ed.)Tetramisole
Thiabendazole
2-substituted benzimidazole first introduced in 1962. it is active against a variety of nematodes and is the drug of choice for strongyloidiasis. it has central nervous system side effects and hepatototoxic potential. (from smith and reynard, textbook of pharmacology, 1992, p919)
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
Present on Admission (POA)
T37.4X4S is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
POA Indicator | Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |

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 T37.4X4 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.
