About coding Hypovolemia
The ICD-10-CM code for Hypovolemia is E86.1 (Hypovolemia). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E86.1.
Within E86 (volume depletion), E86.1 is specifically for Hypovolemia. Related codes cover Dehydration (E86.0) and unspecified (E86.9).
Use an additional code(s) for any associated disorders of electrolyte and acid-base balance (E87.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
