Hypovolemia

This code represents a state of decreased intravascular fluid volume, often resulting from dehydration, hemorrhage, or excessive fluid loss. It signifies a reduction in the body's circulating blood plasma volume, which can lead to inadequate tissue perfusion and organ dysfunction if uncorrected.

Use this code when documentation clearly indicates a diagnosis of hypovolemia, such as in cases of severe dehydration due to vomiting/diarrhea, significant blood loss from trauma or surgery, or third-spacing of fluids. Supporting documentation should specify the cause or clinical indicators of reduced circulating volume.

• Differentiate from dehydration (E86.0) unless the physician specifically diagnoses hypovolemia.
• Always code the underlying cause of hypovolemia (e.g., hemorrhage, gastroenteritis) first, if known and applicable.
• Ensure documentation supports the diagnosis, including clinical signs like hypotension, tachycardia, or decreased urine output.
