ICD-10-CM Code I35

Nonrheumatic aortic valve disorders

Version 2021 Non-Billable Code

Not Valid for Submission

I35 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of nonrheumatic aortic valve disorders. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

ICD-10:I35
Short Description:Nonrheumatic aortic valve disorders
Long Description:Nonrheumatic aortic valve disorders

Consider the following ICD-10 codes with a higher level of specificity:

  • I35.0 - Nonrheumatic aortic (valve) stenosis
  • I35.1 - Nonrheumatic aortic (valve) insufficiency
  • I35.2 - Nonrheumatic aortic (valve) stenosis with insufficiency
  • I35.8 - Other nonrheumatic aortic valve disorders
  • I35.9 - Nonrheumatic aortic valve disorder, unspecified

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I35:

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • aortic valve disorder of unspecified cause but with diseases of mitral and/or tricuspid valves I08
  • aortic valve disorder specified as congenital Q23.0 Q23.1
  • aortic valve disorder specified as rheumatic I06
  • hypertrophic subaortic stenosis I42.1

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Other forms of heart disease (I30-I52)
      • Nonrheumatic aortic valve disorders (I35)

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.
