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:
- Hypernatremia of newborn (KB63.21)
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:
- Hyponatremia of newborn (KB63.20)
Acidosis
Definition of Acidosis: Acidosis is an abnormally acidic state of the blood and tissues.
ICD 11 Code For Acidosis
5C73 Acidosis
Exclusions:
- diabetic acidosis (BlockL2‑5A1)
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.
