Specific code icon 2014 ICD-10-CM Diagnosis Code R00.1

Bradycardia, unspecified

  • R00.1 is a billable ICD-10-CM code that can be used to specify a diagnosis.
  • On October 1, 2014 ICD-10-CM will replace ICD-9-CM in the United States, therefore, R00.1 and all other ICD-10-CM codes should only be used for training or planning purposes until then.
Clinical Information
  • A disorder characterized by a dysrhythmia with a heart rate less than 60 beats per minute that originates in the sinus node.
  • A heart rate of less than 60 beats per minute, with its origin in the sinus node.
  • An abnormally slow heartbeat; as applied in adult medicine, it is generally defined as a heart rate of under 60 beats per minute.
  • Cardiac arrhythmias that are characterized by excessively slow heart rate, usually below 50 beats per minute in human adults. They can be classified broadly into sinoatrial node dysfunction and atrioventricular block.
  • Excessive slowness in the action of the heart, usually with a heart rate below 60 beats per minute.
  • Non-sinus origin slow heart rate.
