Medicaid Payment Delays Deter Physician Participation
Health Affairs Study: Slow Payment Offset Lure of Higher Medicaid Physician Fees
FURTHER INFORMATION, CONTACT:
Previous research has shown that about half of U.S. physicians accept all new Medicaid patients, compared with more than 70 percent of physicians accepting all new privately insured and Medicare patients. Medicaid fee levels vary considerably across states, and research has consistently shown that Medicaid participation by physicians is higher in states with higher fees than in states with lower fees.
While state policy makers often use higher payment rates to increase physician participation and improve access for Medicaid patients, less attention has been paid to the role of administrative burdensincluding payment delayson physicians decisions to treat Medicaid patients.
The new Health Affairs study, titled "Do Reimbursement Delays Discourage Medicaid Participation by Physicians?" examined the effect of variation in average reimbursement times across states on physicians willingness to accept Medicaid patients. The study demonstrates that payment delays can offset the effects of higher Medicaid payment rates on physician participation.
"Medicaid payment rates matter, but the hassle factor also matters, and this study strongly suggests that higher Medicaid fees wont have the desired effect of increasing access if physicians have to wait months to get paid," said HSC Senior Fellow Peter J. Cunningham, Ph.D., coauthor of the study with HSC Senior Researcher Ann S. OMalley, M.D., M.P.H.
The study, funded by the Robert Wood Johnson Foundation, linked information from the nationally representative 2004-05 Community Tracking Study Physician Survey on physician willingness to treat Medicaid patients with 2006 state-level Medicaid claims data on average reimbursement times from athenahealth Inc., a firm that contracts with physician practices to process Medicaid and commercial insurance claims. The study included about 4,900 physicians in 21 states, including most of the largest states, such as New York, California, Texas, Florida, Illinois, Pennsylvania and Michigan.
