The State of Georgia established a Medicaid Managed Care Program known as Georgia Better Health Care (GBHC) in 1994. Recipients were phased into GBHC by groups of counties over a 16 quarter period.

A goal of GBHC was to reduce unnecessary utilization of medical services. Prior to GBHC, many Medicaid recipients received primary care services from hospital emergency departments (ED.) A significant reduction in ED utilization was a measurable objective of GBHC.

GBHC was phased in over an extended period, making possible comparisons in ED utilization rates between GBHC members and non-members for the total Medicaid population and the TANF, SOBRA and SSI sub-populations. Non-GBHC members had a mean rate of 0.1983 per member for the first four quarters of the phase-in period. Sub-population rates were 0.1707, 0.1811 and 0.2390 for TANF, SOBRA and SSI .

For the four quarter period after the phase-in was completed, utilization rates declined to 0.1254, 0.1163, 0.1118 and 0.1611 for the population, TANF, SOBRA and SSI sub-populations, respectively.

Prior to the fourth quarter of 1996, GBHC paid for ED care only if approved by the recipient’s primary care provider. The Balanced Budget Act of 1997 required reimbursement by GBHC if the recipient reasonably believed that emergency care was necessary. Georgia Medicaid officials were concerned that ED utilization rates would return to pre-GBHC levels, CY99 (last year of available data) mean rates of 0.1264, 0.1355, 0.1178 and 0.1571 for the population, TANF, SOBRA and SSI sub-populations suggest that this has not been the case.
