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)

T50.1X5S is a billable diagnosis code used to specify a medical diagnosis of adverse effect of loop [high-ceiling] diuretics, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

T50.1X5S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like adverse effect of loop [high-ceiling] diuretics. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Clinical Classification

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 an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.

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

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Present on Admission (POA)

T50.1X5S is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Convert T50.1X5S to ICD-9-CM

  • ICD-9-CM Code: 909.5 - Lte efct advrs efct drug
    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: E944.4 - Adv eff diuretics 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 T50.1X5 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.

Drug Reactions

Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.

What is a drug interaction?

A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:

  • Two drugs, such as aspirin and blood thinners
  • Drugs and food, such as statins and grapefruit
  • Drugs and supplements, such as gingko and blood thinners
  • Drugs and medical conditions, such as aspirin and peptic ulcers

Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.

What are side effects?

Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.

What are drug allergies?

Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.

How can I stay safe when taking medicines?

When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.

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.
