In simple words: This code signifies a slower-than-normal heart rate, without specifying the underlying cause.It includes conditions like a slow heartbeat originating from the sinus node (the heart's natural pacemaker), or a slow heartbeat due to vagal nerve stimulation.

Bradycardia, unspecified.Includes:Sinoatrial bradycardia, Sinus bradycardia, Slow heart beat, Vagal bradycardia.Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).Excludes1: neonatal bradycardia (P29.12)

Example 1: A 70-year-old patient who exercises regularly presents with a heart rate of 50 beats per minute.The physician diagnoses sinus bradycardia., A patient experiences a slow heart rate after taking a new medication. The physician documents bradycardia, unspecified, and uses an additional code to identify the drug., A patient presents with fatigue and dizziness. An ECG reveals a slow heart rate.Further investigation is needed to determine the cause, so the physician initially codes it as bradycardia, unspecified.

Documentation should specify the type of bradycardia if known (e.g., sinus, sinoatrial, vagal).If a drug is suspected to be the cause, this should be documented as well.ECG findings supporting the diagnosis of bradycardia should be included.

** This code is used when a more specific diagnosis cannot be made after investigation, the bradycardia is transient and the cause cannot be determined, or as a provisional diagnosis.It is important to document all relevant findings and investigations to support the use of this code.
