ICD Code I35.9

ICD code I35.9 is nonrheumatic aortic valve disorder, unspecified. This means there is a problem with the aortic valve of the heart that is not caused by rheumatic fever, but the exact nature of the disorder is not specified.

1. Presence of aortic valve abnormality not attributed to rheumatic fever or rheumatic heart disease

2. Clinical evidence of aortic valve dysfunction, such as stenosis, regurgitation, or other structural abnormality

3. Absence of clear etiology for the aortic valve disorder after evaluation

4. Patient may present with symptoms such as chest pain, dyspnea, syncope, or heart murmur

5. Diagnostic imaging (e.g., echocardiogram) confirms aortic valve disorder without specific underlying cause

6. No documentation of rheumatic origin or other specified cause for the aortic valve disorder

Relevant CPT codes that may be used to treat ICD code I35.9 include:

- 33405: Replacement, aortic valve, with cardiopulmonary bypass

- 33430: Replacement, aortic valve, with cardiopulmonary bypass and removal of prosthesis

- 33361: Transcatheter aortic valve replacement (TAVR/TAVI), percutaneous femoral artery approach

- 33362: Transcatheter aortic valve replacement (TAVR/TAVI), transapical exposure

- 93306: Echocardiography, transthoracic, real-time with image documentation, complete

- 93451: Right heart catheterization

- 93452: Left heart catheterization

- 93567: Injection procedure during cardiac catheterization; for selective coronary angiography

- 93580: Percutaneous transcatheter closure of congenital cardiac defect

These CPT codes are commonly associated with the management and treatment of I35.9.
