The ICD-10 code for essential (primary) hypertension is I10.
However, it's important to understand that "hypertension" is a broad term, and other ICD-10 codes exist for different types and classifications of hypertension. Here's a breakdown:
-
I10: Essential (primary) hypertension - This is the most common type of hypertension, where the cause is not directly attributable to another medical condition.
-
I15: Secondary Hypertension - This type of hypertension is caused by another medical condition. Subcategories include:
- I15.8: Other secondary hypertension
- I15.9: Secondary hypertension, unspecified
-
I16: Hypertensive Crisis - This category covers hypertensive emergencies and urgencies.
- I16.0: Hypertensive urgency
- I16.1: Hypertensive emergency
Therefore, while I10 is the code for essential hypertension, the specific ICD-10 code used will depend on the type of hypertension the patient has. A doctor must diagnose the specific type of hypertension before the correct ICD-10 code can be assigned.
