I15.91: Secondary hypertension, unspecified With mention of hypertensive urgency
You have high blood pressure. Your blood pressure is very high at the moment.
The heart pumps blood through the arteries to every part of the body. The pressure in the arteries must be enough for all the organs to get enough blood. On the other hand, if the blood pressure is too high, the heart, kidneys or other organs may get damaged. Under stress, our blood pressure naturally rises. During the night, our blood pressure usually falls.
The metric for blood pressure always consists of two figures. The first figure is the maximum pressure in the arteries. It occurs when the heart pumps blood out. The second value is the minimum pressure in the arteries. It occurs when the heart is filling up with blood again. A normal blood pressure can be around 120 over 80. Depending on age or pre-existing conditions, a normal blood pressure can also be slightly higher or lower.
High blood pressure is when the blood pressure in the arteries is too high for a long period of time. Your high blood pressure is being caused by another disorder.
Initially, high blood pressure often causes no, or few, appreciable symptoms. If the blood pressure is high over a long period, over time blood vessels and organs can become damaged. It can particularly affect the heart and kidneys.
If the blood pressure increases dramatically, headaches, nosebleeds, dizziness or chest pain may result. And organs such as the heart and brain can quickly become damaged.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

- V: Tentative diagnosis
