ICD-10-CM Code E87.6


Version 2020 Billable Code

Valid for Submission

E87.6 is a billable code used to specify a medical diagnosis of hypokalemia. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code E87.6 might also be used to specify conditions or terms like acute hypokalemia, chronic hypokalemia, dietary potassium - low, dietary potassium intake - finding, dietary potassium intake - finding, drug-induced hypokalemia, etc

Short Description:Hypokalemia
Long Description:Hypokalemia

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code E87.6:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

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

  • Acute hypokalemia
  • Chronic hypokalemia
  • Dietary potassium - low
  • Dietary potassium intake - finding
  • Dietary potassium intake - finding
  • Drug-induced hypokalemia
  • Hypokalemia
  • Hypokalemia with normal acid-base balance
  • Hypokalemia, ECF to ICF shifts
  • Hypokalemia, gastrointestinal losses
  • Hypokalemia, inadequate intake
  • Hypokalemic acidosis
  • Inadequate dietary intake of potassium
  • Nutritional myopathy
  • Paraneoplastic hypokalemia
  • Potassium depletion myopathy

Clinical Information

  • HYPOKALEMIA-. abnormally low potassium concentration in the blood. it may result from potassium loss by renal secretion or by the gastrointestinal route as by vomiting or diarrhea. it may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis by electrocardiographic abnormalities depression of the t wave and elevation of the u wave by renal disease and by gastrointestinal disorders. dorland 27th ed
  • GITELMAN SYNDROME-. an inherited renal disorder characterized by defective nacl reabsorption in the convoluted distal kidney tubule leading to hypokalemia. in contrast with bartter syndrome gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria and is caused by mutations in the thiazide sensitive sodium potassium chloride symporters.

Diagnostic Related Groups

The ICD-10 code E87.6 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2019 through 09/30/2020.

Information for Patients

Fluid and Electrolyte Balance

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help

  • Balance the amount of water in your body
  • Balance your body's acid/base (pH) level
  • Move nutrients into your cells
  • Move wastes out of your cells
  • Make sure that your nerves, muscles, the heart, and the brain work the way they should

Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.

The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

Potassium is a mineral that your body needs to work properly. It is a type of electrolyte. It helps your nerves to function and muscles to contract. It helps your heartbeat stay regular. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium's harmful effects on blood pressure.

Many people get all the potassium they need from what they eat and drink. Sources of potassium in the diet include

  • Leafy greens, such as spinach and collards
  • Fruit from vines, such as grapes and blackberries
  • Root vegetables, such as carrots and potatoes
  • Citrus fruits, such as oranges and grapefruit

Your kidneys help to keep the right amount of potassium in your body. If you have chronic kidney disease, your kidneys may not remove extra potassium from the blood. Some medicines also can raise your potassium level. You may need a special diet to lower the amount of potassium that you eat.
