ICD-10 Code I16.0 – Hypertensive urgency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I16.0 – Hypertensive urgency
What it is
Hypertensive urgency is a severe elevation in blood pressure without clear evidence of acute target-organ damage. Use this code when the record documents urgent blood pressure elevation but not a hypertensive emergency.
Clinical signs
Clinical features vary; refer to documentation. Patients may have markedly elevated blood pressure and symptoms such as headache, anxiety, or shortness of breath, but there is no documented acute organ injury.
When to use this code
Use I16.0 when the provider documents hypertensive urgency, severe asymptomatic hypertension, or urgent blood pressure elevation without emergency findings. It is appropriate when the note clearly separates this condition from hypertensive emergency. Check documentation if the record is vague or mixed.
Do not use for
Do not use this code for hypertensive emergency or for hypertension without urgency. If acute target-organ damage is present or suspected, code the emergency condition instead. Check documentation.
Coding tip
Code only when the provider explicitly documents urgency and no acute organ damage.
