ICD Code E87.0

ICD code E87.0 is hyperosmolality and hypernatremia, which refers to an abnormal increase in the concentration of sodium and other solutes in the blood, often due to dehydration or underlying medical conditions.

1. Serum sodium concentration greater than 145 mEq/L

2. Serum osmolality elevated above normal reference range

3. Clinical evidence of dehydration, such as dry mucous membranes, decreased skin turgor, or hypotension

4. Neurological symptoms including confusion, lethargy, irritability, or seizures

5. History of inadequate water intake, excessive water loss (e.g., fever, sweating, diarrhea), or impaired thirst mechanism

6. Laboratory findings excluding other causes of hyperosmolality (e.g., hyperglycemia, renal failure)

7. Absence of significant hyperglycemia or other solute diuresis as primary cause
