Understanding ICD-10 Code for Mitral Regurgitation
ICD-10 code mitral regurgitation refers to the specific classification used within the International Classification of Diseases, Tenth Revision (ICD-10), to identify and categorize cases of mitral regurgitation (MR). Accurate coding is essential for clinical documentation, billing, epidemiological studies, and health data analysis. Mitral regurgitation, a common valvular heart disorder, involves the backward flow of blood from the left ventricle into the left atrium during systole. Properly understanding the ICD-10 coding for this condition helps healthcare professionals communicate effectively, ensure proper reimbursement, and contribute to health statistics tracking.
Overview of Mitral Regurgitation
What is Mitral Regurgitation?
Mitral regurgitation (also called mitral insufficiency) is a valvular heart disease characterized by the incomplete closure of the mitral valve during systole. This defect allows blood to flow backward into the left atrium, leading to volume overload, atrial dilation, and potentially heart failure if left untreated.
Types of Mitral Regurgitation
Mitral regurgitation can be classified based on its etiology:
1. Primary (Organic) Mitral Regurgitation: Due to structural abnormalities of the mitral valve apparatus, including leaflet prolapse, rheumatic disease, or infective endocarditis.
2. Secondary (Functional) Mitral Regurgitation: Usually caused by left ventricular dilation or dysfunction, leading to papillary muscle displacement and annular dilation without intrinsic valve disease.
Symptoms and Diagnosis
Patients with mitral regurgitation may be asymptomatic initially. As the disease progresses, symptoms may include:
- Fatigue
- Shortness of breath, especially with exertion
- Palpitations
- Swelling in the legs and abdomen
Diagnosis involves echocardiography, which assesses the severity of regurgitation, the size of the ventricles and atria, and the function of the heart.
ICD-10 Coding for Mitral Regurgitation
ICD-10 Codes for Mitral Regurgitation
The ICD-10 coding system classifies mitral regurgitation under the umbrella of valvular heart diseases. The primary codes include:
- I34.0: Nonrheumatic mitral valve insufficiency
- I34.1: Rheumatic mitral valve insufficiency
- I34.2: Mitral valve prolapse
- I34.8: Other nonrheumatic mitral valve diseases
- I34.9: Mitral valve disease, unspecified
Note: These codes are part of the broader category of I34, which encompasses nonrheumatic mitral valve disorders. Rheumatic mitral regurgitation has its specific code, I05.0, under rheumatic mitral disease.
Distinguishing Between Rheumatic and Nonrheumatic Mitral Regurgitation
The differentiation is essential because it affects coding:
- Rheumatic mitral regurgitation: Usually associated with rheumatic fever, and coded under I05.0.
- Nonrheumatic mitral regurgitation: Often due to degenerative changes, prolapse, or other causes, coded under I34.x.
Additional Coding Considerations
Clinicians should specify:
- Severity of regurgitation (mild, moderate, severe)
- Presence of complications such as atrial fibrillation
- Associated conditions like heart failure or atrial dilation
While the ICD-10 does not specify severity in the codes, documentation should reflect it for clinical purposes.
Clinical Significance of Accurate ICD-10 Coding
Impact on Patient Care and Management
Precise coding ensures that the patient's medical record accurately reflects their condition, influencing treatment plans, surgical decisions, and follow-up strategies.
Billing and Reimbursement
Correct ICD-10 coding is crucial for insurance claims processing. Errors can lead to claim denials or delays, affecting hospital revenue and patient billing.
Epidemiological and Public Health Data
Accurate coding enables health authorities to monitor disease prevalence, identify trends, and allocate resources effectively for valvular heart diseases.
Common Coding Scenarios for Mitral Regurgitation
Scenario 1: Primary Nonrheumatic Mitral Regurgitation
- Code: I34.0
- Description: Used when a patient has degenerative mitral regurgitation without rheumatic involvement.
- Documentation: Echocardiogram confirming mitral insufficiency, no evidence of rheumatic disease.
Scenario 2: Rheumatic Mitral Regurgitation
- Code: I05.0
- Description: When mitral regurgitation is due to rheumatic heart disease.
- Documentation: History of rheumatic fever, echocardiography findings.
Scenario 3: Mitral Valve Prolapse
- Code: I34.2
- Description: When prolapse is identified as the primary pathology causing regurgitation.
- Documentation: Clinical findings and echocardiography.
Scenario 4: Other or Unspecified Mitral Valve Disease
- Code: I34.8 or I34.9
- Description: When the specific etiology is unclear or other nonrheumatic causes are present.
Special Considerations in ICD-10 Coding
Concurrent Conditions
When coding for mitral regurgitation, clinicians should also document and code:
- Heart failure (e.g., I50.x)
- Atrial fibrillation (e.g., I48.x)
- Endocarditis (e.g., I33.x) if applicable
This comprehensive documentation ensures accurate representation of the patient's clinical picture.
Severity and Stage Documentation
While ICD-10 codes do not specify severity, clinical records should note the regurgitation's severity, as it impacts management and prognosis.
Use of Additional Codes
In some cases, additional codes may be necessary to specify complications or procedural interventions, such as mitral valve repair or replacement.
Conclusion
Accurate coding of mitral regurgitation using ICD-10 codes is vital for effective clinical communication, appropriate billing, and epidemiological data collection. Understanding the distinctions between different types of mitral regurgitation, the relevant codes, and the importance of detailed documentation enhances patient care and health system efficiency. Healthcare providers should stay current with coding guidelines and ensure comprehensive medical records to facilitate proper classification of this common valvular disorder.

Frequently Asked Questions
What is the ICD-10 code for mitral regurgitation?
The ICD-10 code for mitral regurgitation varies depending on its severity and whether it is acute or chronic. The most common code is I34.0 for nonrheumatic mitral (valve) prolapse, but for general mitral regurgitation, you might use I34.1 (nonrheumatic mitral (valve) insufficiency) or I34.8 (other nonrheumatic mitral valve disorders).
How is chronic mitral regurgitation coded in ICD-10?
Chronic mitral regurgitation is typically coded as I34.1, which refers to nonrheumatic mitral (valve) insufficiency, unless specified otherwise by the clinician.
What ICD-10 codes are used for acute mitral regurgitation?
Acute mitral regurgitation may be coded as I34.0 for nonrheumatic mitral (valve) prolapse with acute mitral regurgitation or other specific codes depending on the cause and presentation, often using I34.8 for other nonrheumatic mitral valve disorders.
Are there specific ICD-10 codes for rheumatic mitral regurgitation?
Yes, rheumatic mitral regurgitation is coded under I05.0 (rheumatic mitral insufficiency) or I05.1, depending on the specifics of the disease process.
How does ICD-10 distinguish between mitral regurgitation and mitral stenosis?
ICD-10 codes differentiate between mitral regurgitation (e.g., I34.1, I34.8) and mitral stenosis (e.g., I05.0, I05.1). Each condition has distinct codes reflecting the specific valve pathology.
Can ICD-10 codes for mitral regurgitation be used for billing and documentation?
Yes, accurate ICD-10 coding for mitral regurgitation is essential for billing, documentation, and ensuring proper classification of the patient's condition during medical record keeping.
Are there any recent updates to ICD-10 codes related to mitral regurgitation?
As of October 2023, the ICD-10 codes for mitral regurgitation remain consistent, but clinicians should consult the latest ICD-10 updates or coding guidelines for any recent revisions or clarifications.
What factors influence the choice of ICD-10 code for a patient with mitral regurgitation?
The choice of ICD-10 code depends on factors such as the cause of regurgitation (rheumatic, degenerative, ischemic), severity (acute or chronic), presence of complications, and whether the condition is primary or secondary.
