ICD-10-CM Code For Multiple Valve Diseases: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I08 includes chronic rheumatic involvement of multiple cardiac valves, such as combined mitral and aortic valve disorders, and other combinations of two or more valves affected by rheumatic disease. These ICD-10-CM diagnosis codes are used to document patient encounters where rheumatic heart disease affects multiple valves, capturing disease severity, valve involvement, and clinical complexity relevant to surgical planning or long-term management. Accurate coding within the ICD-10-CM I08 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM I08: Multiple Valve Diseases Overview

The ICD-10-CM I08 group represents chronic rheumatic involvement of two or more cardiac valves, including combinations of mitral, aortic, tricuspid, and pulmonary valve disease. These diagnoses target the cardiovascular system and reflect structural and functional valvular abnormalities due to rheumatic heart disease. Accurate coding matters for correct severity capture and reimbursement because it documents the complexity and organ systems affected.

When to Use

Use a code from this group when rheumatic heart disease is documented as involving multiple valves rather than an isolated single-valve lesion. Codes apply in clinical records that specify combinations of valve pathology, for example mitral and aortic regurgitation or stenosis attributable to rheumatic disease.

Typical Clinical Scenarios

An elderly patient with a history of untreated rheumatic fever presents for routine cardiology follow-up with progressive exertional dyspnea, a new holosystolic murmur, and echocardiography showing combined mitral stenosis with aortic regurgitation and reduced left ventricular function. The visit documents chronic valvular deformities due to rheumatic disease and guides long‑term medical management and surveillance for valve intervention, so a multiple rheumatic valve disease code is assigned. Typical codes: I08.0, I08.1
A middle‑aged patient arrives to the emergency department with acute pulmonary edema and hypotension after weeks of worsening fatigue; urgent echocardiogram reveals severe chronic rheumatic involvement of both mitral and tricuspid valves with new decompensation attributable to progressive regurgitation. Because the acute presentation is due to exacerbation of underlying chronic rheumatic multi‑valve disease, an appropriate code from this group is used to capture the rheumatic etiology of the multiple valve lesions driving the emergency admission. Typical codes: I08.2, I08.3
A younger adult with a known history of chronic rheumatic heart disease is hospitalized for infective endocarditis on a previously rheumatic mitral and aortic valve, complicating long‑standing multi‑valve rheumatic deformities; care documents both the infective process and the chronic rheumatic valve lesions as contributing factors to clinical management. The coder assigns a code for chronic rheumatic multiple valve disease to reflect the underlying structural valvular abnormalities that are comorbid with the acute infection. Typical codes: I08.8, I08.9
