Medical Policy Statement:
Implantable carotid sinus baroreflex activation therapy will not be considered medically
reasonable and necessary. A review of the current literature shows that the evidence is
insufficient to determine that this service is standard medical treatment. There remains
an absence of randomized, blinded clinical studies examining benefit and long-term
outcomes establishing the value of this service in clinical management.
Definitions:
The Barostim Neo System Kit - Is a medical device designed to treat CHF. The
kit includes an implantable pulse generator (IPG), an implant adapter and implant
tool, a carotid sinus lead (CSL), a CSL repair kit, and a wireless programmer
system (consisting of a programmer interface, software, and a computer). The
IPG is surgically inserted under the collar bone and connected to the carotid
artery via a 2 millimeter (mm) electrode. The IPG stimulates the baroreceptors
approximately 40 times more frequently than a pacemaker
CHF- Congestive Heart Failure
Description:
Barostim was FDA approved in 2019 as an implanted device for patients with systolic
heart failure. The device sends electrical signals to trigger the body’s own natural blood
flow regulation system. Unlike a pacemaker, it is not connected to the heart. The
device utilizes neuromodulation, the power of the brain and nervous system, to improve
the symptoms of patients with systolic heart failure. A person’s body senses changes in
blood pressure and other blood flow changes through pressure sensors (baroreceptors)
that are found on the carotid artery and in the carotid sinus. These sensors measure

and report blood flow to the brain, which compares it to the body’s needs. The Barostim
device is implanted under the collarbone and attached with thin leads to the carotid
artery. The implanted device communicates with an external device doctors use to
noninvasively regulate the activation energy therapy from the device to the leads. The
device sends electrical pulses to baroreceptors located in the wall of the carotid artery.
Baroreceptors trigger the body’s main cardiovascular reflex called the baroreflex, which
in turn triggers an autonomic response to the heart. “Autonomic” means it is part of the
body’s systems that are not consciously controlled by the brain. When activated,
signals are sent through neural pathways to the brain that responds by telling the:
• Arteries to relax, making it easier for blood to flow through the body and reducing
cardiac exertion
• Heart to slow down, allowing more time for the organ to fill with blood
• Kidneys to reduce fluid in the body, lowering both excessive blood pressure and
workload on the heart
The therapy is designed to restore balance to the autonomic nervous system and
reduce the symptoms of heart failure.
