- Aortic Stenosis ICD10 I35.0 belongs to a specific classification category associated with disorders involving the aortic valve; specifically, it indicates nonrheumatic valve stenosis.
- 0 is an official ICD-10-CM medical system code used by healthcare professionals to define diagnoses for billing and reimbursement purposes.
- I35.0 belongs to the American version of ICD-10-CM and may vary slightly between countries due to differing implementation of it and codes being different across borders.

NOTE: When converting between ICD-9-CM and ICD-10-CM codes, it’s important to consider clinical context for the most accurate conversion.
Clinical Information:
- The heart contains four valves; these include the tricuspid, mitral, pulmonary, and aortic valves, which each open or close as necessary to allow bloodflow or protect it against backflow. All four of these are necessary for regulating the proper functions within its chambers.
- The tricuspid and mitral valves both open and close based on the tension of the muscles that surround them. Both valves have collagen fibres that connect directly to the papillary muscles through tendon connections.
- Semilunar valves include those found on the aortic and pulmonary arches; on the other hand, tricuspid and mitral (known collectively as “atrioventricular”) valves are believed to help move blood from the atria into the ventricles more effectively.
- Aortic stenosis is the realization that the size of the aortic valve opening is narrow, and its operation is impaired. The heart works with more effort in order to pump the blood while the pressure increases on the left ventricle, resulting in thickening.
