Disorders Of Fluid Electrolyte Or Acid-Base Balance – ICD 11 Codes

Volume depletion

ICD 11 Code For Volume depletion

5C70  Volume depletion

Exclusions:

  • Hypovolaemic shock (MG40.1)

5C70.0 Dehydration

Definition of Dehydration: Dehydration occurs when there is an insufficient amount or excessive loss of water in the body. This can be caused by vomiting, diarrhoea, fever, use of diuretics, profuse sweating, or decreased water intake.

Coded Elsewhere:

  • Dehydration of newborn (KB63.1)

5C70.1 Hypovolaemia

Definition of Hypovolaemia: This is a state of decreased blood volume; more specifically, decrease in volume of blood plasma. It is thus the intravascular component of volume contraction (or loss of blood volume due to things such as haemorrhaging or dehydration), but, as it also is the most essential one, hypovolemia and volume contraction are sometimes used synonymously.

Exclusions:

  • Traumatic shock, not elsewhere classified (NF0A.4)
  • Hypovolaemic shock (MG40.1)

5C70.Y Other specified volume depletion

5C70.Z Volume depletion unspecified

Hyperosmolality or hypernatraemia

Definition of Hyperosmolality or hypernatraemia: Serum sodium concentrations in excess of 145 mmol/L; increased serum concentration of osmotically active particles

ICD 11 Code For Hyperosmolality or hypernatraemia

  5C71  Hyperosmolality or hypernatraemia

Coded Elsewhere:

Hypo-osmolality or hyponatraemia

Definition of Hypo-osmolality or hyponatraemia: Serum sodium concentrations of less than 135 mEq/L; decreased serum concentration of osmotically active particles

ICD 11 Code For Hypo-osmolality or hyponatraemia

  5C72  Hypo-osmolality or hyponatraemia

Inclusions:

  • sodium [na] deficiency

Exclusions:

Coded Elsewhere:

Acidosis

Definition of Acidosis: Acidosis is an abnormally acidic state of the blood and tissues.

ICD 11 Code For Acidosis

  5C73  Acidosis

Exclusions:

Coded Elsewhere:

  • Kussmaul respiration (5A22.Y)

5C73.0 Acute respiratory acidosis

Definition of Acute respiratory acidosis: This is an acute condition in which decreased ventilation (hypoventilation) causes increased blood carbon dioxide concentration and decreased pH (a condition generally called acidosis). Carbon dioxide is produced continuously as the body’s cells respire, and this CO2 will accumulate rapidly if the lungs do not adequately expel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased PaCO2 (called hypercapnia). The increase in PaCO2 in turn decreases the HCO3-/PaCO2 ratio and decreases pH.

5C73.1 Chronic respiratory acidosis

Definition of Chronic respiratory acidosis: This is a chronic condition in which decreased ventilation (hypoventilation) causes increased blood carbon dioxide concentration and decreased pH (a condition generally called acidosis). Carbon dioxide is produced continuously as the body’s cells respire, and this CO2 will accumulate rapidly if the lungs do not adequately expel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased PaCO2 (called hypercapnia). The increase in PaCO2 in turn decreases the HCO3?/PaCO2 ratio and decreases pH.

5C73.2 Anion gap metabolic acidosis

Definition of Anion gap metabolic acidosis: This is a form of metabolic acidosis characterised by a high anion gap. The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap.

5C73.Y Other specified acidosis

5C73.Z Acidosis unspecified

Alkalosis

Definition of Alkalosis: Alkalosis is an abnormally basic state of the blood and tissues.

ICD 11 Code For Alkalosis

  5C74  Alkalosis

Mixed disorder of acid-base balance

Definition of Mixed disorder of acid-base balance: This is a condition where more than one of the normal mechanisms that regulate the amount of acid or base content in the body are dysfunctional.

ICD 11 Code For Mixed disorder of acid-base balance

  5C75  Mixed disorder of acid-base balance

Hyperkalaemia

ICD 11 Code For Hyperkalaemia

  5C76  Hyperkalaemia

Inclusions:

  • Potassium [K] excess
  • Potassium [K] overload

Coded Elsewhere:

  • Hyperkalaemia of newborn (KB63.31)

Hypokalaemia

ICD 11 Code For Hypokalaemia

  5C77  Hypokalaemia

Coded Elsewhere:

  • Hypokalaemia of newborn (KB63.30)

Fluid overload

Definition of Fluid overload: This is the condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in extracellular body water. The mechanism usually stems from compromised regulatory mechanisms for sodium handling as seen in congestive heart failure (CHF), kidney failure, and liver failure. It may also be caused by excessive intake of sodium from foods, intravenous (IV) solutions and blood transfusions, medications, or diagnostic contrast dyes.
