An Essential Disclaimer At this time, no decisions have been made or even proposed by the Department of Health Care Services. This material is solely the responsibility of ACS, A Xerox Company, in its capacity as a consultant to DHCS. This simulation is for illustrative purposes only and also does not reflect an ACS recommendation. 2
Steps Toward Recommending Payment Policy 1. Criteria and context 2. Choice of APR-DRG relative weights 3. Taking into account the managed care transition 4. Initial simulation focuses on Medicaid care category 5. Impact evaluated on hospitals by geographic area and type of hospital to consider possibility of different base prices 6. Impact evaluated on hospitals in terms of magnitude of change => consider possibility of transition period 3 At this time, no payment policy decisions have been proposed or made by DHCS
Step 1: Criteria / Context for Inpatient Rates Medicaid goal is access to quality care for beneficiaries Assumed hospital goals are mission and margin Hospital mission (especially if tax-exempt) includes community service Hospital decisions to build, expand and promote services reflect relative margins by care category Medicaid payment rates matter most in care categories where Medicaid has significant market share Payment exceeding variable cost matters in the short term; payment exceeding total cost matters in the long term Planning for change negative or positive matters to hospitals 4 At this time, no payment policy decisions have been proposed or made by DHCS
National Market Shares by Care Category California data will be presented in September. Patterns are expected to be very similar. 5 At this time, no payment policy decisions have been proposed or made by DHCS
Steps 2-4: Initial Simulation 2) Choice of APR-DRG relative weights National weights based on NIS (including CA) Relative weights based on Medi-Cal historical data 3) Major transition between CY 2009 and FY 2013 Expansion of managed care by county and aid category MCO rates not part of FFS DRG payment project Need to model impact of DRG payment with view to FY 2013 4) Initial statewide simulation by Medicaid Care Category Do relative pay-to-cost ratios encourage access? If necessary, some states use budget-neutral policy adjustors to boost payment for specific care categories 6 At this time, no payment policy decisions have been proposed or made by DHCS
Steps 5-6: Evaluate Impact on Hosp Access 5) Evaluate impact by geographic area and hospital category Are groups of hospitals systematically advantaged or systematically disadvantaged? Does jeopardy to access (geographic or otherwise) justify different DRG base prices or other consideration? Medicare varies DRG base price for 29 wage areas in CA 6) Evaluate impact in terms of change management Hospitals typically need time to manage major changes Evaluate impacts in terms of magnitude of Medi-Cal payment change within overall financial picture Medicare (a significant larger payer for some, not all, services) typically allows transition period of several years 7 At this time, no payment policy decisions have been proposed or made by DHCS

Proposed Next Steps Try for consensus on approach Calculate CA relative weights as alternative to national Drill down into simulation results, e.g., patterns of outlier stays, individual stays with major dollar changes Updates as needed to hospital-specific CCRs, NPI consolidations, geographic and peer group assignments, etc. Re-do simulation, aiming for budget neutrality Evaluate impacts of simulation on various hospital groupings (e.g., wage area, hospital type) different base prices? Evaluate impacts of simulation in terms of percentage changes transition period? Consider documentation and coding adjustment 13 At this time, no payment policy decisions have been proposed or made by DHCS
