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)

T37.3X2S is a billable diagnosis code used to specify a medical diagnosis of poisoning by other antiprotozoal drugs, intentional self-harm, 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.

T37.3X2S 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 other antiprotozoal drugs intentional self-harm. 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

  • Emetine

    the principal alkaloid of ipecac, from the ground roots of uragoga (or cephaelis) ipecacuanha or u. acuminata, of the rubiaceae. it is used as an amebicide in many different preparations and may cause serious cardiac, hepatic, or renal damage and violent diarrhea and vomiting. emetine inhibits protein synthesis in eukaryotic cells but not prokaryotic cells.
  • Glaucarubin

    (1 beta,2 alpha,11 beta,12 alpha,15 beta(s))-11,20-epoxy-1,2,11,12-tetrahydroxy-15-(2-hydroxy-2-methyl-1-oxobutoxy)picras-3-en-16-one. a quassinoid (simaroubolide) from simaruba glauca, a tropical shrub. it has been used as an antiamebic agent and is found to be cytotoxic. it may be of use in cancer chemotherapy.
  • Melarsoprol

    arsenical used in trypanosomiases. it may cause fatal encephalopathy and other undesirable side effects.
  • Misonidazole

    a nitroimidazole that sensitizes normally radio-resistant hypoxic cells to radiation. it may also be directly cytotoxic to hypoxic cells and has been proposed as an antineoplastic.
  • Nifurtimox

    a nitrofuran thiazine that has been used against trypanosomiasis.
  • Nimorazole

    an antitrichomonal agent which is effective either topically or orally and whose urinary metabolites are also trichomonicidal.
  • Ornidazole

    a nitroimidazole antiprotozoal agent used in ameba and trichomonas infections. it is partially plasma-bound and also has radiation-sensitizing action.
  • Pentamidine

    antiprotozoal agent effective in trypanosomiasis, leishmaniasis, and some fungal infections; used in treatment of pneumocystis pneumonia in hiv-infected patients. it may cause diabetes mellitus, central nervous system damage, and other toxic effects.
  • Tinidazole

    a nitroimidazole alkylating agent that is used as an antitrichomonal agent against trichomonas vaginalis; entamoeba histolytica; and giardia lamblia infections. it also acts as an antibacterial agent for the treatment of bacterial vaginosis and anaerobic bacterial infections.

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)

T37.3X2S 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.

Convert T37.3X2S to ICD-9-CM

  • ICD-9-CM Code: 909.0 - Late eff drug poisoning
    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: E959 - Late eff of self-injury
    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 T37.3X2 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.
