I16.9
ICD-10-CMThis code represents a severe and acute elevation in blood pressure without further specification of whether it constitutes a hypertensive urgency or emergency. It indicates a significant, sudden rise in blood pressure that requires prompt medical attention but lacks details regarding target organ damage.
Use this code when documentation clearly states "hypertensive crisis" but does not specify the presence or absence of acute target organ damage (e.g., encephalopathy, acute kidney injury, pulmonary edema). It is appropriate when the provider has not differentiated between hypertensive urgency and emergency.
