Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    (R00–R99)
    • Symptoms and signs involving the circulatory and respiratory systems
      (R00-R09)
      • Abnormalities of heart beat
        (R00)

R00 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of abnormalities of heart beat. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The code is commonly used in cardiology medical specialties to specify clinical concepts such as abnormalities of heart rhythm.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Specific Coding Applicable to Abnormalities of heart beat

Non-specific codes like R00 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for abnormalities of heart beat:

  • Use R00.0 for Tachycardia, unspecified - BILLABLE CODE

  • Use R00.1 for Bradycardia, unspecified - BILLABLE CODE

  • Use R00.2 for Palpitations - BILLABLE CODE

  • Use R00.8 for Other abnormalities of heart beat - BILLABLE CODE

  • Use R00.9 for Unspecified abnormalities of heart beat - BILLABLE CODE

Patient Education


Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include:

  • Fast or slow heart beat
  • Skipping beats
  • Lightheadedness or dizziness
  • Chest pain
  • Shortness of breath
  • Sweating

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.
