RT Welter & Associates is excited to present our monthly Code Spotlight! Each month, RT Welter & Associates will spotlight a unique CPT or ICD-10 code to profile and discuss practice applications of the code, as well as pertinent guideline reminders.
ICD-10 Code I16 – Hypertensive Crisis
- I16.0 — Hypertensive Urgency, which should be reported when a patient has a systolic blood pressure equal to or greater than 180 or a diastolic pressure greater than 110 in the absence of associated organ damage or dysfunction, he or she is said to be in hypertensive urgency. Immediate blood pressure reduction is often not necessary and acute complications are unlikely, but the patient will need his or her medication adjusted and blood pressure monitored more closely to ensure it continues to stay at a suitable level.
- I16.1— Hypertensive emergency, which should be reported when a patient is experiencing a hypertensive emergency when blood pressure levels exceed 180 systolic over 120 diastolic and organ damage is present. The organ systems typically affected include cardiac, renal, and neurologic, manifested as coronary ischemia, disturbed cerebral function, renal failure, cerebrovascular events, and pulmonary edema. These cases require intensive care hospital admission for immediate but controlled blood pressure reduction via IV medications. Complete work-up and evaluation should be completed to determine the underlying cause or trigger of the hypertensive emergency.
- I16.9 — Hypertensive crisis NOS, which should be reported when there is a life-threatening rapid increase in a patient’s blood pressure. The presence or absence of associated organ damage further classifies the type of hypertensive crisis as urgent or emergent.
