Clinical Information

  • Acetazolamide

    one of the carbonic anhydrase inhibitors that is sometimes effective against absence seizures. it is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. however, its usefulness is transient often because of rapid development of tolerance. its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition. (from smith and reynard, textbook of pharmacology, 1991, p337)
  • Amiloride

    a pyrazine compound inhibiting sodium reabsorption through sodium channels in renal epithelial cells. this inhibition creates a negative potential in the luminal membranes of principal cells, located in the distal convoluted tubule and collecting duct. negative potential reduces secretion of potassium and hydrogen ions. amiloride is used in conjunction with diuretics to spare potassium loss. (from gilman et al., goodman and gilman's the pharmacological basis of therapeutics, 9th ed, p705)
  • Bendroflumethiazide

    a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. it has been used in the treatment of familial hyperkalemia, hypertension, edema, and urinary tract disorders. (from martindale, the extra pharmacopoeia, 30th ed, p810)
  • Chlormerodrin

    a mercurial compound that has been used as a diuretic but is now superseded by more potent and less toxic drugs. the radiolabeled form has been used as a diagnostic and research tool.
  • Chlorothiazide

    a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p812)
  • Chlorthalidone

    a benzenesulfonamide-phthalimidine that tautomerizes to a benzophenones form. it is considered a thiazide-like diuretic.
  • Clopamide

    a sulfamoylbenzamide piperidine. it is considered a thiazide-like diuretic.
  • Cyclopenthiazide

    thiazide diuretic also used as an antihypertensive agent.
  • Dichlorphenamide

    a carbonic anhydrase inhibitor that is used in the treatment of glaucoma.
  • Ethoxzolamide

    a carbonic anhydrase inhibitor used as diuretic and in glaucoma. it may cause hypokalemia.
  • Hydrochlorothiazide

    a thiazide diuretic often considered the prototypical member of this class. it reduces the reabsorption of electrolytes from the renal tubules. this results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. it is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.
  • Hydroflumethiazide

    a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p822)
  • Mefruside

    a benzene-sulfonamide-furan. it is used as a diuretic that affects the concentrating ability of the kidney, increases sodium chloride excretion, but may not spare potassium. it inhibits carbonic anhydrases and may increase the blood uric acid level.
  • Mersalyl

    a toxic thiol mercury salt formerly used as a diuretic. it inhibits various biochemical functions, especially in mitochondria, and is used to study those functions.
  • Methazolamide

    a carbonic anhydrase inhibitor that is used as a diuretic and in the treatment of glaucoma.
  • Methyclothiazide

    a thiazide diuretic with properties similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p825)
  • Metolazone

    a quinazoline-sulfonamide derived diuretic that functions by inhibiting sodium chloride symporters.
  • Polythiazide

    a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p826)
  • Triamterene

    a pteridinetriamine compound that inhibits sodium reabsorption through sodium channels in renal epithelial cells.
  • Trichlormethiazide

    a thiazide diuretic with properties similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p830)
  • Fosfomycin

    an antibiotic produced by streptomyces fradiae.
  • Tromethamine

    an organic amine proton acceptor. it is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer. (from merck, 11th ed; martindale, the extra pharmacopoeia, 30th ed, p1424)
  • Xipamide

    a sulfamoylbenzamide analog of clopamide. it is diuretic and saluretic with antihypertensive activity. it is bound to plasma proteins, thus has a delayed onset and prolonged action.

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 diuretics and other and unspecified drugs, medicaments and biological substances (T50). Use the following options for the aplicable episode of care:

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

Table of Drugs and Chemicals

The 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.
