ICD-10-CM Code For Hypertensive Heart Disease: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I11 includes diagnoses of hypertensive heart disease, covering heart conditions caused by long-standing hypertension such as left ventricular hypertrophy and heart failure attributable to high blood pressure. These ICD-10-CM diagnosis codes are used to document clinical scenarios where cardiac involvement is secondary to systemic hypertension, capturing disease severity, organ involvement, and clinical complexity relevant to this group. Accurate coding within the ICD-10-CM I11 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM I11: Hypertensive Heart Disease Overview

This group represents heart disease caused by chronic high blood pressure affecting cardiac structure and function, including hypertrophy and heart failure related to hypertension. It targets the cardiovascular system and specifically the heart complications secondary to systemic hypertension. Accurate coding matters for reimbursement because it documents the link between hypertension and cardiac complications, which affects claim processing and severity capture.

When to Use

Use a code from this group when clinical documentation indicates that heart disease is caused by or directly related to systemic hypertension. Select the code that reflects the specific cardiac manifestation and whether heart failure or other complications are present.

I11.9	Hypertensive heart disease without heart failure

DRG Codes

DRG Code	Description
291	Heart Failure and Shock with MCC

305	Hypertension without MCC
791	Prematurity with Major Problems
793	Full Term Neonate with Major Problems

Typical Clinical Scenarios

An older adult with a long history of poorly controlled hypertension presents to the clinic with progressive exertional dyspnea and lower extremity edema. Echocardiography shows concentric left ventricular hypertrophy and reduced diastolic function consistent with hypertensive heart disease without acute heart failure; the visit documents chronic cardiac changes attributed to systemic hypertension. Typical codes: I11.9.
A middle-aged patient arrives to the emergency department with acute onset shortness of breath, orthopnea, and bibasilar crackles; blood pressure is markedly elevated and chest x-ray demonstrates pulmonary edema. The presentation is interpreted as hypertensive heart disease manifesting as acute congestive heart failure requiring urgent medical management, so a code indicating hypertensive heart disease with heart failure is assigned. Typical codes: I11.0.
A patient with chronic kidney disease and long-standing hypertension is seen during a nephrology follow-up; chart review documents left ventricular hypertrophy attributed to the hypertension and notes it as a comorbid cardiac diagnosis impacting overall management. Because the cardiac condition is secondary to systemic hypertension and recorded as hypertensive heart disease, the corresponding diagnosis code is used. Typical codes: I11.9.
