Access to physicians' services for vulnerable Medicare beneficiaries
1Center for Health Economics Research, Waltham, MA 02452-8414, USA.
Summary
Changes to Medicare physician reimbursement did not significantly affect care access. However, substantial utilization gaps persist between vulnerable and nonvulnerable Medicare beneficiaries for primary care and high-cost procedures.
Area of Science:
- Health Services Research
- Health Economics
- Public Health Policy
Background:
- Physician reimbursement policies, such as the Medicare Fee Schedule (MFS), can influence healthcare access.
- Understanding differential impacts on vulnerable populations is crucial for equitable healthcare delivery.
Purpose of the Study:
- To investigate if Medicare Fee Schedule (MFS) payment changes differentially affected access to care for vulnerable versus nonvulnerable Medicare beneficiaries.
- To identify disparities in healthcare utilization between these groups.
Main Methods:
- Utilized a quasi-experimental research design leveraging cross-sectional payment variations.
- Employed a stratified random sample to ensure adequate representation of vulnerable Medicare beneficiaries.
- Developed service-specific measures of MFS payment changes.
Main Results:
- Few significant effects of MFS changes on overall access to care were identified.
- Substantial utilization gaps were observed between vulnerable and nonvulnerable subpopulations.
- Disparities were noted in primary care services and high-cost procedures during acute myocardial infarction episodes.
Conclusions:
- Medicare Fee Schedule (MFS) payment adjustments showed limited impact on healthcare access.
- Significant and persistent utilization gaps exist for vulnerable Medicare beneficiaries.
- Targeted interventions may be needed to address disparities in care for vulnerable populations.
