Final answer:
The correct code that indicates sinus arrest is 427.5. Sinus arrest is a condition where there is a pause in the normal electrical signal from the sinoatrial (SA) node. This pause can result in a temporary cessation of the heartbeat or a slowing down of the heart rate.
Step-by-step explanation:
The correct code that indicates sinus arrest is 427.5.
Sinus arrest is a condition where there is a pause in the normal electrical signal from the sinoatrial (SA) node, which is responsible for initiating the heartbeat. This pause can result in a temporary cessation of the heartbeat or a slowing down of the heart rate. In medical coding, the International Classification of Diseases (ICD) is used to assign codes to specific conditions, and in this case, the code 427.5 is used to indicate sinus arrest.
