Health Care Utilization of US Medicare Beneficiaries Living with Parkinson’s Disease

The number of people living with Parkinson’s disease (PD) is expected to rise in the coming years. This study analyzed health care utilization patterns of Medicare beneficiaries with a PD diagnosis (ICD-10 code G20) who were enrolled in 2019. Utilization analysis included PD-related specialists and primary care physicians, therapy services, and mental health services. We found 685,116 (1.2%) Medicare beneficiaries had PD (56.3% male, 77.9% over age 70, 85.3% White, and 16.0% rural residents). Few Medicare beneficiaries with PD sought care from a movement disorder specialist (MDS) (9.1%); another 50.9% visited a general neurologist. Results reveal low utilization rates for therapy and even lower rates for mental health services. Overall healthcare utilization varied significantly by demographic group with women, people of color, and rural residents being less likely to access specialist care. Our findings emphasize the need for further research on population-specific barriers to accessing PD-related health care.
