What I05 covers · when clinicians use it
ICD-10 code I05 identifies Rheumatic mitral valve diseases in the U.S. ICD-10-CM clinical and billing record set. It sits within the Circulatory System chapter (I00–I99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply I05 when an encounter's findings match the Rheumatic mitral valve diseases description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify I05 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for I05 and is a coding reference, not clinical, diagnostic, or billing advice.
I05 refers to Rheumatic mitral valve diseases, which are long-term complications of rheumatic fever affecting one or more heart valves. These disorders often result in valvular stenosis, regurgitation, or a combination of both, leading to impaired cardiac function and increased risk of heart failure, arrhythmias, and stroke.
Symptoms
- Shortness of breath – Especially with exertion or when lying down
- Fatigue – Due to reduced cardiac output
- Palpitations – From arrhythmias like atrial fibrillation
- Chest pain – May occur in advanced valvular disease
- Swelling in legs or abdomen – Sign of heart failure, especially with I07 tricuspid involvement
- Murmurs – Audible on auscultation depending on the valve affected
- Dizziness or fainting – Especially in severe aortic stenosis (I06)
Diagnosis
Diagnosis of Rheumatic mitral valve diseases includes echocardiography (to assess valve function and structure), electrocardiogram, chest X-ray, and clinical evaluation of murmurs. Cardiac MRI or catheterization may be required in complex or surgical cases. A history of rheumatic fever often guides diagnosis.
ICD10 Code Usage
ICD10 code I05 is used by cardiologists, internists, and cardiothoracic surgeons. It aids in documenting valve pathology, treatment planning (medications, valve repair/replacement), eligibility for long-term anticoagulation, and insurance coding for follow-up and procedures.
Related Codes
- I06 – Rheumatic aortic valve diseases
- I07 – Rheumatic tricuspid valve diseases
- I08 – Multiple valve diseases
- I09 – Other rheumatic heart diseases
FAQs
Q1: What is ICD10 code I05?
A: It refers to Rheumatic mitral valve diseases, which are chronic valvular diseases caused by prior rheumatic fever, affecting mitral, aortic, tricuspid, or multiple valves.
Q2: Can these conditions be cured?
A: Damage is permanent but symptoms can be managed with medication or surgery (e.g., valve repair or replacement).
Q3: What is the most commonly affected valve?
A: The mitral valve (I05) is most frequently involved, especially in young adults from regions with high rheumatic fever prevalence.
Q4: Are these conditions preventable?
A: Yes—early treatment of streptococcal infections and long-term antibiotic prophylaxis can prevent rheumatic heart disease.
Q5: Who manages these conditions?
A: Cardiologists manage the condition, with surgeons involved if valve replacement is needed.
Conclusion
ICD10 code I05 plays a key role in diagnosing and managing Rheumatic mitral valve diseases, ensuring proper care planning, long-term monitoring, and surgical intervention when needed to maintain cardiac function and prevent complications.
