2025 ICD-10-CM code I16
(Active) Effective Date: N/A Diseases of the circulatory system - Hypertensive diseases IX Feed
Hypertensive crisis. Code also any identified hypertensive disease (I10-I15, I1A).
Medical necessity for the use of I16 is established by the documentation of a hypertensive emergency or urgency. This is typically determined by significantly elevated blood pressure readings accompanied by target organ damage or severe symptoms.
Clinicians should document the specific type of hypertensive disease along with any underlying causes or contributing factors. Accurate recording of blood pressure readings, signs, and symptoms associated with the crisis is essential.
In simple words: This code represents a hypertensive crisis, a severe increase in blood pressure that can lead to serious complications.It's used along with other codes to specify what kind of high blood pressure problem the patient has.
Hypertensive crisis. This code should be used in conjunction with codes I10-I15 or I1A to specify the type of hypertensive disease present.
Example 1: A patient with pre-existing essential hypertension (I10) presents to the emergency room with severely elevated blood pressure (220/120 mmHg), headache, and blurred vision, indicative of a hypertensive crisis (I16)., A pregnant woman with pre-eclampsia (O14.93) develops a sudden, dangerous spike in blood pressure, qualifying as a hypertensive crisis (I16), requiring immediate medical intervention., A patient with chronic kidney disease (N18.9) and known renovascular hypertension (I12.0) experiences a hypertensive crisis (I16) with symptoms of dizziness and shortness of breath.
Documentation should include the patient's blood pressure readings, the presence and severity of symptoms (e.g., headache, chest pain, vision changes), and any associated conditions or triggers. Any treatment provided and the patient's response should also be documented.
** Excludes1: neonatal hypertension (P29.2), primary pulmonary hypertension (I27.0). Excludes2: hypertensive disease complicating pregnancy, childbirth, and the puerperium (O10-O11, O13-O16).
