ICD Code I34.9

ICD code I34.9 is nonrheumatic mitral valve disorder, unspecified. This means there is a problem with the mitral valve of the heart that is not caused by rheumatic fever, but the exact nature of the disorder is not specified.

1. Presence of a mitral valve disorder that is not attributable to rheumatic heart disease

2. Clinical evidence of mitral valve dysfunction, such as regurgitation or stenosis, without a specified underlying cause

3. Absence of documentation specifying the exact type of nonrheumatic mitral valve disorder

4. Symptoms may include heart murmur, dyspnea, fatigue, palpitations, or signs of heart failure

5. Diagnostic imaging (e.g., echocardiogram) indicating mitral valve abnormality without clear etiology

6. No evidence or history of rheumatic fever or rheumatic heart disease

7. Provider documentation explicitly states a nonrheumatic mitral valve disorder but does not further specify the condition

Relevant CPT codes that may be used to treat ICD code I34.9 include:

- 93306 – Echocardiography, transthoracic, real-time with image documentation (2D), includes M-mode recording, complete, with spectral Doppler echocardiography and with color flow Doppler echocardiography

- 93451 – Right heart catheterization

- 93452 – Left heart catheterization

- 93458 – Catheter placement in coronary arteries for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation

- 33430 – Replacement, mitral valve, with cardiopulmonary bypass

- 33426 – Mitral valve repair, with cardiopulmonary bypass

- 93567 – Injection procedure during cardiac catheterization; for selective coronary angiography (in addition to primary procedure)

- 93568 – Injection procedure during cardiac catheterization; for pulmonary angiography (in addition to primary procedure)

- 93580 – Percutaneous transcatheter closure of congenital interatrial communication (e.g., Fontan fenestration, atrial septal defect), with implant

These CPT codes are commonly associated with the evaluation and management of I34.9.
