Valid for Submission
R00.1 is a billable diagnosis code used to specify a medical diagnosis of bradycardia, unspecified. The code R00.1 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code R00.1 might also be used to specify conditions or terms like abnormal pulse rate, borderline slow pulse, bradycardia, bradycardic cardiac arrest, drug-induced bradycardia , o/e - pulse borderline slow, etc.
The code is commonly used in cardiology medical specialties to specify clinical concepts such as abnormalities of heart rhythm.
Unspecified diagnosis codes like R00.1 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
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.
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 R00.1:
Inclusion TermsInclusion 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.
- Sinoatrial bradycardia
- Sinus bradycardia
- Slow heart beat
- Vagal bradycardia
Use Additional CodeUse Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
Type 1 ExcludesType 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.

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 R00.1 are found in the index:
- - Brachycardia - R00.1
- - Bradycardia (sinoatrial) (sinus) (vagal) - R00.1
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Abnormal pulse rate
- Borderline slow pulse
- Bradycardic cardiac arrest
- Drug-induced bradycardia
- O/E - pulse borderline slow
- O/E - pulse rate
- O/E - pulse rate
- O/E - pulse rate
- O/E - pulse rate - bradycardia
- O/E - pulse rate very slow
- Persistent sinus bradycardia
- Pulse slow
- Reflex bradycardia
- Severe sinus bradycardia
- Sinus bradycardia
- Symptomatic sinus bradycardia
- Vagal autonomic bradycardia
- Vagal autonomic bradycardia of prematurity
- BRADYCARDIA-. 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.

Convert R00.1 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code R00.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Also called: Irregular heartbeat
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
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.
