ICD-10-CM Code I08.0

Rheumatic disorders of both mitral and aortic valves

Version 2020 Billable Code

Valid for Submission

I08.0 is a billable code used to specify a medical diagnosis of rheumatic disorders of both mitral and aortic valves. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code I08.0 might also be used to specify conditions or terms like aortic cusp regurgitation, aortic cusp regurgitation, diseases of mitral and aortic valves, mitral and aortic incompetence, mitral and aortic stenosis, mitral insufficiency and aortic stenosis, etc

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 I08.0:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Involvement of both mitral and aortic valves specified as rheumatic or unspecified

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I08.0 are found in the index:

Diagnostic Related Groups

The ICD-10 code I08.0 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).

Information for Patients

Heart Valve Diseases

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.

Streptococcal Infections

Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B.

Group A strep causes

  • Strep throat - a sore, red throat. Your tonsils may be swollen and have white spots on them.
  • Scarlet fever - an illness that follows strep throat. It causes a red rash on the body.
  • Impetigo - a skin infection
  • Toxic shock syndrome
  • Cellulitis and necrotizing fasciitis (flesh-eating disease)

Group B strep can cause blood infections, pneumonia and meningitis in newborns. A screening test during pregnancy can tell if you have it. If you do, intravenous (IV) antibiotics during labor can save your baby's life. Adults can also get group B strep infections, especially if they are 65 or older or already have health problems. Strep B can cause urinary tract infections, blood infections, skin infections and pneumonia in adults.

Antibiotics are used to treat strep infections.
