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)

T37.0X4D is a billable diagnosis code used to specify a medical diagnosis of poisoning by sulfonamides, undetermined, subsequent 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. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T37.0X4D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like poisoning by sulfonamides undetermined. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Clinical Classification

Clinical Information

  • Acedapsone

    acetylated sulfone that is slowly metabolized to give long-term, low blood levels of dapsone. it has antimicrobial and antimalarial action, but is mainly used as a depot leprostatic agent.
  • Sulfachlorpyridazine

    a sulfonamide antimicrobial used for urinary tract infections and in veterinary medicine.
  • Silver Sulfadiazine

    antibacterial used topically in burn therapy.
  • Sulfadiazine

    one of the short-acting sulfonamides used in combination with pyrimethamine to treat toxoplasmosis in patients with acquired immunodeficiency syndrome and in newborns with congenital infections.
  • Sulfadimethoxine

    a sulfanilamide that is used as an anti-infective agent.
  • Sulfadoxine

    a long acting sulfonamide that is used, usually in combination with other drugs, for respiratory, urinary tract, and malarial infections.
  • Sulfaguanidine

    a sulfanilamide antimicrobial agent that is used to treat enteric infections.
  • Sulfalene

    long-acting plasma-bound sulfonamide used for respiratory and urinary tract infections and also for malaria.
  • Sulfamerazine

    a sulfanilamide that is used as an antibacterial agent.
  • Sulfameter

    long acting sulfonamide used in leprosy, urinary, and respiratory tract infections.
  • Sulfamethazine

    a sulfanilamide anti-infective agent. it has a spectrum of antimicrobial action similar to other sulfonamides.
  • Sulfamethizole

    a sulfathiazole antibacterial agent.
  • Sulfamethoxazole

    a bacteriostatic antibacterial agent that interferes with folic acid synthesis in susceptible bacteria. its broad spectrum of activity has been limited by the development of resistance. (from martindale, the extra pharmacopoeia, 30th ed, p208)
  • Trimethoprim, Sulfamethoxazole Drug Combination

    a drug combination with broad-spectrum antibacterial activity against both gram-positive and gram-negative organisms. it is effective in the treatment of many infections, including pneumocystis pneumonia in aids.
  • Sulfamethoxypyridazine

    a sulfanilamide antibacterial agent.
  • Sulfamonomethoxine

    long acting sulfonamide antibacterial agent.
  • Sulfamoxole

    a sulfanilamide antibacterial agent.
  • Sulfanilamide

    a short-acting sulfonamide used as an anti-infective agent. it has lower anti-bacterial activity than sulfamethoxazole.
  • Sulfanilamides

    compounds based on 4-aminobenzenesulfonamide. the '-anil-' part of the name refers to aniline.
  • Sulfaphenazole

    a sulfonilamide anti-infective agent.
  • Sulfapyridine

    antibacterial, potentially toxic, used to treat certain skin diseases.
  • Sulfasalazine

    a drug that is used in the management of inflammatory bowel diseases. its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see mesalamine) released in the colon. (from martindale, the extra pharmacopoeia, 30th ed, p907)
  • Sulfathiazole

    a sulfathiazole compound that is used as a short-acting anti-infective agent. it is no longer commonly used systemically due to its toxicity, but may still be applied topically in combination with other drugs for the treatment of vaginal and skin infections, and is still used in veterinary medicine.
  • Sulfathiazoles

    sulfanilamides consisting of a 4-aminobenzenesulfonamido group at the 2-position of 1,3-thiazole. they are often used as anti-infective agents.
  • Sulfisomidine

    a sulfanilamide antibacterial agent.
  • Sulfisoxazole

    a short-acting sulfonamide antibacterial with activity against a wide range of gram- negative and gram-positive organisms.

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)

T37.0X4D 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 IndicatorReason for CodeCMS will pay the CC/MCC DRG?
YDiagnosis was present at time of inpatient admission.YES
NDiagnosis was not present at time of inpatient admission.NO

Convert T37.0X4D to ICD-9-CM

  • ICD-9-CM Code: V58.89 - Other specfied aftercare
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Drugs and Chemicals

The parent code T37.0X4 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.
