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 affecting the cardiovascular system
        (T46)

T46.6X4A is a billable diagnosis code used to specify a medical diagnosis of poisoning by antihyperlipidemic and antiarteriosclerotic 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.

T46.6X4A 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 antihyperlipidemic and antiarteriosclerotic 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

  • Bezafibrate

    an antilipemic agent that lowers cholesterol and triglycerides. it decreases low density lipoproteins and increases high density lipoproteins.
  • Clofibrate

    a fibric acid derivative used in the treatment of hyperlipoproteinemia type iii and severe hypertriglyceridemia. (from martindale, the extra pharmacopoeia, 30th ed, p986)
  • Colestipol

    highly crosslinked and insoluble basic anion exchange resin used as anticholesteremic. it may also may reduce triglyceride levels.
  • Fenofibrate

    an antilipemic agent which reduces both cholesterol and triglycerides in the blood.
  • Gemfibrozil

    a lipid-regulating agent that lowers elevated serum lipids primarily by decreasing serum triglycerides with a variable reduction in total cholesterol.
  • Halofenate

    an antihyperlipoproteinemic agent and uricosuric agent.
  • Linoleic Acid

    a doubly unsaturated fatty acid, occurring widely in plant glycosides. it is an essential fatty acid in mammalian nutrition and is used in the biosynthesis of prostaglandins and cell membranes. (from stedman, 26th ed)
  • Linoleic Acids

    eighteen-carbon essential fatty acids that contain two double bonds.
  • Linoleic Acids, Conjugated

    a collective term for a group of around nine geometric and positional isomers of linoleic acid in which the trans/cis double bonds are conjugated, where double bonds alternate with single bonds.
  • Linoleoyl-CoA Desaturase

    an enzyme that catalyzes the syn-dehydrogenation of linoleol-coa gamma-linolenoyl-coa. it was formerly characterized as ec 1.14.99.25.
  • Lovastatin

    a fungal metabolite isolated from cultures of aspergillus terreus. the compound is a potent anticholesteremic agent. it inhibits 3-hydroxy-3-methylglutaryl coenzyme a reductase (hydroxymethylglutaryl coa reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. it also stimulates the production of low-density lipoprotein receptors in the liver.
  • Oleic Acid

    an unsaturated fatty acid that is the most widely distributed and abundant fatty acid in nature. it is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. (stedman, 26th ed)
  • Oleic Acids

    a group of fatty acids that contain 18 carbon atoms and a double bond at the omega 9 carbon.
  • Ricinoleic Acids

    eighteen carbon fatty acids that comprise the great majority of castor oil, which is from the seed of ricinus.
  • Pravastatin

    an antilipemic fungal metabolite isolated from cultures of nocardia autotrophica. it acts as a competitive inhibitor of hmg coa reductase (hydroxymethylglutaryl coa reductases).
  • Probucol

    a drug used to lower ldl and hdl cholesterol yet has little effect on serum-triglyceride or vldl cholesterol. (from martindale, the extra pharmacopoeia, 30th ed, p993).
  • Safflower Oil

    an oily liquid extracted from the seeds of the safflower, carthamus tinctorius. it is used as a dietary supplement in the management of hypercholesterolemia. it is used also in cooking, as a salad oil, and as a vehicle for medicines, paints, varnishes, etc. (dorland, 28th ed & random house unabridged dictionary, 2d ed)
  • Simvastatin

    a derivative of lovastatin and potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme a reductase (hydroxymethylglutaryl coa reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. it may also interfere with steroid hormone production. due to the induction of hepatic ldl receptors, it increases breakdown of ldl cholesterol.
  • Sitosterols

    a family of sterols commonly found in plants and plant oils. alpha-, beta-, and gamma-isomers have been characterized.
  • Triparanol

    antilipemic agent with high ophthalmic toxicity. according to merck index, 11th ed, the compound was withdrawn from the market in 1962 because of its association with the formation of irreversible cataracts.

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 affecting the cardiovascular system (T46). Use the following options for the aplicable episode of care:

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

Convert T46.6X4A to ICD-9-CM

    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 T46.6X4 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.
