Medicaid patients increasingly concentrated among physicians

Area of Science:

• Health Services Research
• Physician Practice Patterns
• Medicaid Policy

Background:

• Medicaid payment rates and enrollment have increased nationally.
• Physician participation in Medicaid is a key factor in patient access to care.

Purpose of the Study:

• To analyze trends in U.S. physician acceptance of Medicaid patients over the past decade.
• To identify factors influencing physician participation in Medicaid.

Main Methods:

• Analysis of national survey data on physician practice and payment.
• Comparison of physician acceptance rates between 1996-97 and 2004-05.

Main Results:

• The percentage of physicians receiving no Medicaid revenue increased from 12.9% to 14.6%.
• Physician care for Medicaid patients is concentrating in larger group practices, hospitals, and health centers.
• Low payment rates and high administrative costs are associated with reduced Medicaid participation, especially in solo/small practices.

Conclusions:

• Physician acceptance of Medicaid patients has declined despite policy changes.
• Care delivery for Medicaid beneficiaries is becoming increasingly concentrated, potentially impacting access.
• Addressing payment rates and administrative burden is crucial for improving physician participation.
