ICD-10-CM Code I35.2

Nonrheumatic aortic (valve) stenosis with insufficiency

Version 2021 Billable Code Cardiology

Valid for Submission

I35.2 is a billable code used to specify a medical diagnosis of nonrheumatic aortic (valve) stenosis with insufficiency. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code I35.2 might also be used to specify conditions or terms like aortic incompetence, non-rheumatic, aortic stenosis, non-rheumatic, aortic valve stenosis with insufficiency, aortic valve stenosis with insufficiency, disorder of aortic valve prosthesis, non-rheumatic aortic valve stenosis with regurgitation, etc

The code is commonly used in cardiology medical specialties to specify clinical concepts such as nonrheumatic valve disorders - aortic valve disorders.

Information for Patients

Heart Valve Diseases

Also called: Valvular heart disease

Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. If they don't, you could have

  • Regurgitation - when blood leaks back through the valve in the wrong direction
  • Mitral valve prolapse - when one of the valves, the mitral valve, has "floppy" flaps and doesn't close tightly. It's one of the most common heart valve conditions. Sometimes it causes regurgitation.
  • Stenosis - when the valve doesn't open enough and blocks blood flow

Valve problems can be present at birth or caused by infections, heart attacks, or heart disease or damage. The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. Heart tests can show if you have a heart valve disease. Some valve problems are minor and do not need treatment. Others might require medicine, medical procedures, or surgery to repair or replace the valve.
