I10 is a valid billable ICD-10 diagnosis code for Essential (primary) hypertension. It is found in the 2020 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2019 - Sep 30, 2020. Essential hypertension is high blood pressure that doesn't have a known secondary cause.
Instead, use the following codes:
ICD-10 code Z01. 30 for Encounter for examination of blood pressure without abnormal findings is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
That code is I10, Essential (primary) hypertension. As in ICD-9, this code includes “high blood pressure” but does not include elevated blood pressure without a diagnosis of hypertension (that would be ICD-10 code R03. 0).
R03. 0: Elevated blood-pressure reading, without diagnosis of hypertension.
401.9 - Unspecified essential hypertension | ICD-10-CM.
ICD-10 Code for Secondary hypertension, unspecified- I15. 9- Codify by AAPC.
0 until the formal diagnosis is established. Although various sources define hypertension slightly differently, the provider should document elevated systolic pressure above 140 or diastolic pressure above 90 with at least two readings on separate office visits.
0.
It's also known as idiopathic or essential hypertension. Above-normal blood pressure is typically anything over 120/80 mmHg. This means that the pressure inside your arteries is higher than it should be.
This category is to be used to record an episode of elevated blood pressure in a patient in whom no formal diagnosis of hypertension has been made, or as an isolated incidental finding.

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 796.2 was previously used, R03.0 is the appropriate modern ICD10 code.
ICD-10-CM classifies HTN by type as essential or primary (categories I10–I13) and secondary (category I15). Report code I10 Essential (primary) hypertension for individuals who meet the criteria for hypertension and do not have any comorbid cardiac or renal disease. This code includes “high blood pressure” but is not meant to be used when elevated blood pressure is noted in an individual that has not been diagnosed with HTN. Report cases of transient HTN with R03.0 Elevated blood-pressure reading, without diagnosis of hypertension.
Hypertension is the medical term for elevated blood pressure — a serious medical condition in which the pressure of the circulating blood against the arterial walls is high enough that it may eventually cause health problems such as heart disease and stroke.
Codes for the three-disease combination are numerically arranged by the degree of CKD and then further differentiated by the presence or absence of heart failure.
But don’t stress; there are a limited number of codes for HTN — only nine codes for primary hypertension and five codes for secondary hypertension.
Coding Hypertensive Heart Disease. Hypertensive heart disease can cause serious health problems and is the No. 1 cause of death associated with HTN. It refers to heart conditions caused by elevated blood pressure.
Hypertension (HTN) is a worldwide epidemic, affecting an estimated 1.13 billion people globally and nearly half of all adults in the United States. That’s roughly 108 million Americans, and only about one in four have their blood pressure under control.
If the provider specifically documents a different cause for the heart condition unrelated to high blood pressure, then the HTN and heart condition should be coded separately and not linked via a combination code. In such cases, sequence according to the circumstances of the admission/encounter.
