Payment source and provider type in the US healthcare system

Area of Science:

• Health Services Research
• Healthcare Policy
• Medical Economics

Background:

• Growing demand for healthcare services in the US necessitates innovative care delivery models.
• Physician assistants (PAs) and nurse practitioners (NPs) are integral to expanding healthcare access and managing costs.
• Existing evidence suggests disparities in healthcare provider reimbursement based on provider type.

Purpose of the Study:

• To investigate variations in medical visit payment sources based on the type of healthcare provider (physician, PA, or NP).
• To understand how insurance and payment models align with different provider roles in ambulatory care settings.

Main Methods:

• Analysis of data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) spanning 2006-2010.
• Statistical examination of payment sources (private insurance, Medicare, Medicaid, out-of-pocket) in relation to the primary provider of care.
• Comparative analysis of care delivery by physicians, PAs, and NPs.

Main Results:

• Physicians were disproportionately more likely to provide care for visits covered by private insurance or Medicare.
• PAs and NPs were more frequently the providers for visits compensated through Medicaid or out-of-pocket payments.
• Significant differences observed in payment structures associated with provider type.

Conclusions:

• Payment sources for medical visits differ significantly based on whether the care is delivered by a physician, PA, or NP.
• These payment variations may influence healthcare access and resource allocation within the US healthcare system.
• Understanding these payment dynamics is crucial for equitable healthcare delivery and policy development.
