Prepayment with office-based physicians in publicly funded programs: results from the Children's Medicaid Program

Area of Science:

• Health economics
• Pediatric healthcare policy
• Physician reimbursement models

Background:

• Medicaid physician payment structures impact healthcare delivery for children.
• Understanding the effects of alternative payment models is crucial for optimizing care.
• Physician financial incentives can influence service utilization and referrals.

Purpose of the Study:

• To provide empirical evidence on the effects of two alternative physician payment models for Medicaid pediatric care.
• To compare utilization and expenditures between visit fees, capitation with risk-sharing, and traditional fee-for-service Medicaid.
• To assess the impact of payment strategies on primary care access and specialist referrals.

Main Methods:

• A demonstration study randomly assigned physicians to two payment groups: higher visit fees or capitation with risk-sharing.
• Utilization and expenditures were compared between the two experimental groups and the standard Medicaid fee-for-service program.
• Data focused on primary care visits and specialist referrals for children in the Medicaid program.

Main Results:

• Capitation payment models showed no adverse impact on primary care office visits for children.
• Physician referrals to specialists significantly decreased under capitation compared to other payment models.
• Findings support the hypothesis that financial incentives in capitation influence primary care physician referral behaviors.

Conclusions:

• Alternative physician payment models, including capitation, can be implemented for Medicaid pediatric services without compromising primary care access.
• Capitation payment strategies may effectively manage specialist utilization, potentially reducing overall healthcare costs.
• Further research into the long-term effects and broader implications of these payment models is warranted.
