The ICD-10 code for essential (primary) hypertension is I10. However, it is important to note that hypertension can also be classified into different categories, each with its own specific ICD-10 code.
Here's a breakdown of some hypertension-related ICD-10 codes:
- I10: Essential (primary) hypertension
- I15.8: Other secondary hypertension
- I15.9: Secondary hypertension, unspecified
- I16.0: Hypertensive urgency
- I16.1: Hypertensive emergency
It is critical to use the most accurate and specific code based on the type of hypertension diagnosed. The reference provided by CMS outlines these various classifications.
