ICD-10-CM Code For Rheumatic Aortic Valve Diseases: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I06 includes chronic rheumatic aortic valve conditions such as rheumatic aortic stenosis, rheumatic aortic insufficiency, and combined aortic valve lesions resulting from prior rheumatic fever. These ICD-10-CM diagnosis codes are used to document chronic valvular dysfunction of the aortic valve, capturing severity, valve involvement, and related cardiac complications such as heart failure or arrhythmia. Accurate coding within the ICD-10-CM I06 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM I06: Rheumatic Aortic Valve Diseases Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I06 represents chronic rheumatic disease affecting the aortic valve, including aortic stenosis, regurgitation, and combined lesions secondary to rheumatic fever. These diagnoses target the cardiovascular system, specifically valvular structure and function of the aortic valve. Accurate coding ensures clinical records reflect disease severity and comorbid cardiac involvement and supports appropriate reimbursement for services related to long-term management and interventions.

When to Use

Use a code from this group when the medical record documents chronic rheumatic disease of the aortic valve with specified stenosis, insufficiency, or combined lesion. Select the code that matches the documented valve lesion and laterality or combined presentation to reflect clinical severity and support claim processing.

ICD-10-CM Code	Description
I06.0	Rheumatic aortic stenosis
I06.1	Rheumatic aortic insufficiency
I06.2	Rheumatic aortic stenosis with insufficiency
I06.8	Other rheumatic aortic valve diseases

Typical Clinical Scenarios

An elderly patient with a history of rheumatic fever presents for routine cardiology follow-up with progressive exertional dyspnea and a new blowing systolic murmur radiating to the carotids. Echocardiography demonstrates thickened, retracted aortic valve leaflets with hemodynamically significant stenosis and reduced valve area consistent with chronic rheumatic aortic stenosis; the visit documents chronic rheumatic involvement of the aortic valve. Typical codes: I06.0, I06.1
A middle-aged patient with long-standing rheumatic heart disease is evaluated for worsening heart failure symptoms including orthopnea and lower extremity edema; imaging reveals mixed aortic valve disease with predominant regurgitation causing volume overload. The clinician documents chronic rheumatic aortic insufficiency as a contributing cause of the cardiac decompensation and schedules valve surveillance and medical optimization. Typical codes: I06.2, I06.8
A young adult with prior untreated rheumatic fever presents to the emergency department with infective endocarditis and acute-on-chronic aortic valve dysfunction leading to hypotension. The record notes chronic rheumatic involvement of the aortic valve as the underlying structural lesion complicating the acute infectious process and guiding surgical consultation. Typical codes: I06.8, I06.9
