Medicaid Reimbursement for Common Orthopedic Procedures Is Not Consistent

Area of Science:

• Health Services Research
• Orthopedic Surgery
• Health Economics

Background:

• Physician reimbursement in the United States primarily consists of Medicare (federally funded) and Medicaid (state funded).
• Medicaid reimbursement oversight mandates that payments do not negatively affect patient care, but allows for significant state-level variability.
• Disparities in reimbursement rates between Medicare and Medicaid may influence healthcare access and provider participation.

Purpose of the Study:

• To quantify the variability of Medicaid reimbursement for common orthopedic procedures across different states.
• To compare state-specific Medicaid reimbursement rates with regional Medicare reimbursement rates.
• To identify specific orthopedic procedures with the greatest reimbursement discrepancies between Medicare and Medicaid.

Main Methods:

• Retrieved state-specific Medicaid reimbursement rates for ten common orthopedic procedures.
• Collected corresponding regional Medicare reimbursement rates for comparison.
• Calculated the average Medicaid reimbursement as a percentage of Medicare reimbursement for each procedure and across all states.
• Analyzed interstate variation in Medicaid reimbursement rates relative to Medicare rates.

Main Results:

• Average Medicaid reimbursement across all analyzed procedures was 81.9% of Medicare reimbursement.
• Significant interstate variation was observed, with Medicaid rates ranging from 37.7% to 147% of Medicare rates.
• Forty states reimbursed at less than 100% of Medicare rates, and twenty states reimbursed at less than 75%.
• Knee arthroplasty reimbursement was relatively high (91.4% of Medicare), while carpal tunnel release was lowest (74.1% of Medicare).
• Anterior cruciate ligament repair exhibited the widest interstate variation, from 20.6% to 229% of local Medicare rates.

Conclusions:

• Substantial and widespread disparities exist between Medicaid and Medicare reimbursement rates for orthopedic procedures.
• The significant variation in Medicaid reimbursement across states and procedures suggests potential inequities in patient access to care.
• Further research is warranted to understand the clinical and economic impact of these reimbursement differences on orthopedic patient outcomes.
