Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Toxic effects of substances chiefly nonmedicinal as to source
      (T51-T65)
      • Toxic effect of other and unspecified substances
        (T65)

T65.91XA is a billable diagnosis code used to specify a medical diagnosis of toxic effect of unspecified substance, accidental (unintentional), 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.

T65.91XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like toxic effect of unspecified substance accidental (unintentional). 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.

Unspecified diagnosis codes like T65.91XA are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

  • Fluoride Poisoning

    poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of fluoride compounds.
  • Foodborne Diseases

    acute illnesses, usually affecting the gastrointestinal tract, brought on by consuming contaminated food or beverages. most of these diseases are infectious, caused by a variety of bacteria, viruses, or parasites that can be foodborne. sometimes the diseases are caused by harmful toxins from the microbes or other chemicals present in the food. especially in the latter case, the condition is often called food poisoning.
  • Gas Poisoning

    poisoning that results from exposure to gases such as carbon monoxide; noble gases; oxygen; or natural gas.
  • Heavy Metal Poisoning

    poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of heavy metals. acute and chronic exposures can cause anemia; kidney and liver damage; pulmonary edema; memory loss and behavioral changes; bone deformities in children; and miscarriage or premature labor in pregnant women.
  • Heavy Metal Poisoning, Nervous System

    conditions associated with damage or dysfunction of the nervous system caused by exposure to heavy metals, which may cause a variety of central, peripheral, or autonomic nervous system injuries.

    poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of lead or lead compounds.
  • Lead Poisoning, Nervous System

    injury to the nervous system secondary to exposure to lead compounds. two distinct clinical patterns occur in children (lead poisoning, nervous system, childhood) and adults (lead poisoning, nervous system, adult). in children, lead poisoning typically produces an encephalopathy. in adults, exposure to toxic levels of lead is associated with a peripheral neuropathy.
  • Lead Poisoning, Nervous System, Adult

    neurologic conditions in adults associated with acute or chronic exposure to lead or any of its salts. the most common lead related neurologic syndrome in adults consists of a polyneuropathy involving motor fibers. this tends to affect distal nerves and may present as wrist drop due to radial neuropathy. additional features of chronic lead exposure include anemia; constipation; colicky abdominal pain; a bluish lead line of the gums; interstitial nephritis (nephritis, interstitial); and saturnine gout. an encephalopathy may rarely occur. (from adams et al., principles of neurology, 6th ed, p1212)
  • Lead Poisoning, Nervous System, Childhood

    neurologic disorders occurring in children following lead exposure. the most frequent manifestation of childhood lead toxicity is an encephalopathy associated with chronic ingestion of lead that usually presents between the ages of 1 and 3 years. clinical manifestations include behavioral changes followed by lethargy; convulsions; hallucinations; delirium; ataxia; and vomiting. elevated intracranial pressure (hypertension, intracranial) and cerebral edema may occur. (from adams et al., principles of neurology, 6th ed, p1210-2)
  • Manganese Poisoning

    manganese poisoning is associated with chronic inhalation of manganese particles by individuals who work with manganese ore. clinical features include confusion; hallucinations; and an extrapyramidal syndrome (parkinson disease, secondary) that includes rigidity; dystonia; retropulsion; and tremor. (adams, principles of neurology, 6th ed, p1213)
  • Mercury Poisoning

    poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of mercury or mercury compounds.

(from joynt, clinical neurology, 1997, ch20, pp10-15)
  • MPTP Poisoning

    a condition caused by the neurotoxin mptp which causes selective destruction of nigrostriatal dopaminergic neurons. clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (parkinson disease, secondary). mptp toxicity is also used as an animal model for the study of parkinson disease. (adams et al., principles of neurology, 6th ed, p1072; neurology 1986 feb;36(2):250-8)

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of other and unspecified substances (T65). Use the following options for the aplicable episode of care:

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

Convert T65.91XA to ICD-9-CM

  • ICD-9-CM Code: 989.9 - Tox eff nonmed subst NOS
    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: E866.8 - Acc pois-solid/liq 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 T65.91 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.
