2025 ICD-10-CM code I10
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Circulatory System - Hypertensive diseases Diseases of the circulatory system Feed
Essential (primary) hypertension; high blood pressure.
Modifiers may be applicable depending on the context of care (e.g., place of service) and the specific services performed. Consult official guidelines for appropriate modifier usage.
Medical necessity for coding I10 is established by sustained high blood pressure measurements exceeding normal ranges.Treatment is deemed medically necessary to prevent long-term complications such as stroke, heart disease, and kidney failure.
The clinical responsibility involves diagnosing hypertension through physical examination, blood pressure measurement, and possibly further investigations to rule out secondary causes.Ongoing monitoring, lifestyle modifications (diet, exercise), and medication management are crucial.
In simple words: This code means high blood pressure that doesn't have a known cause.It's a common condition, and doctors use this code when blood pressure is consistently high without any other clear reason.
This code signifies essential (primary) hypertension, which encompasses high blood pressure without an identifiable underlying cause.It includes hypertension classified as benign, malignant, or unspecified, and is characterized by elevated arterial blood pressure.The diagnosis excludes hypertension secondary to other conditions, such as pregnancy complications or kidney disease.
Example 1: A 55-year-old male presents with persistent elevated blood pressure readings (160/100 mmHg) on multiple occasions, with no clear underlying medical condition.I10 is used to code essential hypertension. , A 70-year-old female with a history of hypertension (I10) experiences a stroke (I61). Both I10 and I61 are coded to reflect both the underlying hypertension and the resulting cerebrovascular event., A 40-year-old patient presents with symptoms suggestive of hypertensive urgency, requiring immediate management to lower blood pressure. I10 is used along with codes indicating the urgency and treatment administered.
Detailed blood pressure readings over time;results of any relevant investigations (e.g., blood tests, echocardiogram) to rule out secondary causes; details of current medications; documentation of lifestyle factors (diet, exercise, smoking history); and any associated complications.
** Always ensure that the documentation supports the diagnosis of essential hypertension and excludes secondary causes.Consider using additional codes for associated comorbidities and complications.
