Stereotactic Pallidotomy
Stereotactic pallidotomy is a surgical technique used in the treatment of severe Parkinson’s disease. Pallidotomy is defined as the surgical creation of a lesion in a globus pallidus in the basal ganglia.
Exclusions
Stereotactic Pallidotomy is limited to one unit of servicea. Stereotactic pallidotomy is not covered when performed with radiation. This is considered investigational and is therefore non-covered by Medicaid.
Bilateral pallidotomy on the same date of service is not covered.
Stereotactic pallidotomy is not covered when any of the following conditions exist:
- 1. Advanced cerebral atrophy, focal lesion, or lacuna of the basal ganglia.
- 2. Advanced disease or other conditions that could explain the neurological
symptoms.
- 3. Atypical Parkinson’s disorder.
- 4. Dementia, cerebral atrophy, or confused state.
Place of Service
Inpatient.

Deep Brain Stimulation (DBS)
Deep brain stimulation (DBS) consists of electrical stimulation of specific sites in the brain with implanted electrodes to reduce the symptoms of movement disorders such as Parkinson’s disease and Essential Tremor. DBS can be done on one or both sides of the brain, depending on the disorder and the beneficiary's symptoms. Once implanted, noninvasive programming of the stimulator can be adjusted to the patient’s symptoms. This is an important feature for patients, whose disease may progress over time, requiring different stimulation parameters. Setting the best stimulation parameters may involve the balance between optimal symptom control and the appearance of side effects of stimulation, such as dysarthria, disequilibrium, or involuntary movements.
Limits
1 unit per date of service
Exclusions
DBS is contraindicated when any of the following are true:
- a. Medical, surgical, neurologic, or orthopedic co-morbidities exist
contraindicating DBS surgery or stimulation.
- b. One or more medical conditions exist that require repeated magnetic
resonance imaging (MRI). MRI can be safely performed under specialized protocols.
- c. Cognitive impairment, dementia, or depression would be worsened by or
would interfere with the beneficiary’s ability to benefit from DBS.
- d. Botulinum toxin injections have been given within the last 4 months.
- e. Diathermy will be used in the future.
Place of Service
Inpatient, Outpatient, and Independent Diagnostic Testing Facilities (IDTF). CPT codes 95970, 95976 and 95977 may be billed in the office setting. CPT codes 95976 and 95977 may be billed in IDTF Centers.
