ICD-10-CM Code E87

Other disorders of fluid, electrolyte and acid-base balance

Version 2021 Non-Billable Code

Not Valid for Submission

E87 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of other disorders of fluid, electrolyte and acid-base balance. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

ICD-10:E87
Short Description:Other disorders of fluid, electrolyte and acid-base balance
Long Description:Other disorders of fluid, electrolyte and acid-base balance

Consider the following ICD-10 codes with a higher level of specificity:

  • E87.0 - Hyperosmolality and hypernatremia
  • E87.1 - Hypo-osmolality and hyponatremia
  • E87.2 - Acidosis
  • E87.3 - Alkalosis
  • E87.4 - Mixed disorder of acid-base balance
  • E87.5 - Hyperkalemia
  • E87.6 - Hypokalemia
  • E87.7 - Fluid overload
  • E87.70 - Fluid overload, unspecified
  • E87.71 - Transfusion associated circulatory overload
  • E87.79 - Other fluid overload
  • E87.8 - Other disorders of electrolyte and fluid balance, not elsewhere classified

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:

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!"

An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • diabetes insipidus E23.2
  • electrolyte imbalance associated with hyperemesis gravidarum O21.1
  • electrolyte imbalance following ectopic or molar pregnancy O08.5
  • familial periodic paralysis G72.3

Code Classification

  • Endocrine, nutritional and metabolic diseases (E00–E90)
    • Metabolic disorders (E70-E88)
      • Other disorders of fluid, electrolyte and acid-base balance (E87)

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, chlorine, 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.
