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 agents primarily acting on smooth and skeletal muscles and the respiratory system
        (T48)

T48.0X4A is a billable diagnosis code used to specify a medical diagnosis of poisoning by oxytocic 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.

T48.0X4A 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 oxytocic 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

  • Carboprost

    a nonsteroidal abortifacient agent that is effective in both the first and second trimesters of pregnancy.
  • Dinoprost

    a naturally occurring prostaglandin that has oxytocic, luteolytic, and abortifacient activities. due to its vasocontractile properties, the compound has a variety of other biological actions.
  • Dinoprostone

    the most common and most biologically active of the mammalian prostaglandins. it exhibits most biological activities characteristic of prostaglandins and has been used extensively as an oxytocic agent. the compound also displays a protective effect on the intestinal mucosa.
  • Ergonovine

    an ergot alkaloid (ergot alkaloids) with uterine and vascular smooth muscle contractile properties.
  • Methylergonovine

    a homolog of ergonovine containing one more ch2 group. (merck index, 11th ed)
  • Cytochrome P-450 CYP2D6

    a cytochrome p450 enzyme that catalyzes the hydroxylation of many drugs and environmental chemicals, such as debrisoquine; adrenergic receptor antagonists; and tricyclic antidepressants. this enzyme is deficient in up to 10 percent of the caucasian population.
  • Sparteine

    a quinolizidine alkaloid isolated from several fabaceae including lupinus; spartium; and cytisus. it has been used as an oxytocic and an anti-arrhythmia agent. it has also been of interest as an indicator of cyp2d6 genotype.

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 agents primarily acting on smooth and skeletal muscles and the respiratory system (T48). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Convert T48.0X4A to ICD-9-CM

  • ICD-9-CM Code: 975.0 - Poisoning-oxytocic agent
    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: E980.4 - Undet pois-med agnt NEC
    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 T48.0X4 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.
