The ICD-10 code for essential (primary) hypertension is I10. However, it is important to note that other ICD-10 codes exist for different types of hypertension.
Hypertension, or high blood pressure, is a common condition, and its classification within the International Classification of Diseases, Tenth Revision (ICD-10) involves several specific codes to distinguish between different types and severities. The most commonly used code is I10, which specifically refers to essential or primary hypertension, meaning high blood pressure that doesn't result from an identifiable underlying cause.
Here's a breakdown of some relevant ICD-10 codes related to hypertension:
- I10: Essential (Primary) Hypertension: This is the most common type of hypertension, where no specific cause can be identified.
- I15.8: Other Secondary Hypertension: This code is used when hypertension is caused by another identifiable condition, such as endocrine disorders or certain medications.
- I15.9: Secondary Hypertension, Unspecified: Used when hypertension is known to be secondary to another condition, but the specific underlying cause is not specified.
- I16.0: Hypertensive Urgency: This code is applied when there is a severe elevation in blood pressure without target organ damage.
- I16.1: Hypertensive Emergency: Used when severe hypertension is accompanied by acute target organ damage (e.g., stroke, heart attack, kidney failure).
Therefore, while I10 is the code for essential hypertension, the appropriate ICD-10 code depends on the specific diagnosis and underlying cause of the high blood pressure. Accurate coding requires a complete medical evaluation to determine the specific type of hypertension.
