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 diuretics and other and unspecified drugs, medicaments and biological substances
        (T50)

T50.1X1A is a billable diagnosis code used to specify a medical diagnosis of poisoning by loop [high-ceiling] diuretics, 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.

T50.1X1A 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 loop [high-ceiling] diuretics 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Accidental bumetanide overdose
  • Accidental ethacrynic acid overdose
  • Accidental furosemide overdose
  • Accidental furosemide poisoning
  • Bumetanide overdose
  • Ethacrynic acid overdose
  • Ethacrynic acid poisoning
  • Furosemide overdose
  • Furosemide poisoning
  • Loop diuretic overdose

Clinical Information

  • Bumetanide

    a sulfamyl diuretic.
  • Sodium Potassium Chloride Symporter Inhibitors

    agents that inhibit sodium-potassium-chloride symporters which are concentrated in the thick ascending limb at the junction of the loop of henle and kidney tubules, distal. they act as diuretics. excess use is associated with hypokalemia and hyperglycemia.
  • Solute Carrier Family 12, Member 1

    na-k-cl transporter in the ascending limb of loop of henle. it mediates active reabsorption of sodium chloride and is inhibited by loop diuretics such as furosemide; and bumetanide. mutations in the gene encoding slc12a1 are associated with a bartter syndrome.
  • Solute Carrier Family 12, Member 2

    na-k-cl transporter ubiquitously expressed. it plays a key role in salt secretion in epithelial cells and cell volume regulation in nonepithelial cells.
  • Ethacrynic Acid

    a compound that inhibits symport of sodium, potassium, and chloride primarily in the ascending limb of henle, but also in the proximal and distal tubules. this pharmacological action results in excretion of these ions, increased urinary output, and reduction in extracellular fluid. this compound has been classified as a loop or high ceiling diuretic.
  • Furosemide

    a benzoic-sulfonamide-furan. it is a diuretic with fast onset and short duration that is used for edema and chronic renal insufficiency.
  • Ticrynafen

    a novel diuretic with uricosuric action. it has been proposed as an antihypertensive agent.

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

Convert T50.1X1A to ICD-9-CM

  • ICD-9-CM Code: 974.4 - Poisoning-diuretics NEC
    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: E858.5 - Acc poisn-metabol agnt

Table of Drugs and Chemicals

The parent code T50.1X1 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


Medication Errors

Medicines treat infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the health care provider's office, at the pharmacy, or at home. You can help prevent errors by:

  • Knowing your medicines. When you get a prescription, ask the name of the medicine and check to make sure that the pharmacy gave you the right medicine. Make sure that you understand how often you should take the medicine and how long you should take it.
  • Keeping a list of medicines.
    • Write down all of the medicines that you are taking, including the names of your medicines, how much you take, and when you take them. Make sure to include any over-the-counter medicines, vitamins, supplements, and herbs that you take.
    • List the medicines that you are allergic to or that have caused you problems in the past.
    • Take this list with you every time you see a health care provider.
  • Reading medicine labels and following the directions. Don't just rely on your memory - read the medication label every time. Be especially careful when giving medicines to children.
  • Asking questions. If you don't know the answers to these questions, ask your health care provider or pharmacist:
    • Why am I taking this medicine?
    • What are the common side effects?
    • What should I do if I have side effects?
    • When should I stop this medicine?
    • Can I take this medicine with the other medicines and supplements on my list?
    • Do I need to avoid certain foods or alcohol while taking this medicine?

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.
