  3. OVERVIEW OF DRG PAYMENT MODELS

  4. OVERVIEW OF DRG MODELS DRG models generally pay a fixed amount, which is known in advance, on a per discharge basis, and based on the patient s DRG assignment DRG Patient Classifications Systems, or Groupers , assign each patient discharge to a DRG, based on the patient s diagnoses, surgical procedures performed, age, gender, birth weight and discharge status Each DRG has a relative weight factor, which recognizes the differences in resource requirements based on patient s assigned DRG Page 4

  5. OVERVIEW OF DRG MODELS Payment is generally determined by multiplying a hospital s base rate by the assigned DRG s relative weight factor An outlier payment provision is typically incorporated to provide additional payments where the base DRG amount is not appropriate generally cases with extraordinarily high costs Payment models are also commonly modified to affect payment for specialty services or providers, including behavioral health, rehabilitation, neonatal, pediatric and others Page 5

  6. OVERVIEW OF DRG MODELS There are two DRG grouper models that are broadly used by public and commercial payers for classifying patients into DRGs All Patient Refined DRGs (APR-DRGs) Medicare Severity DRGs (MS-DRGs) While a number of state Medicaid programs rely on MS- DRGs for DRG payment models, the APR-DRG groper is considered to be a superior model for payments targeted to the Medicaid (i.e., non-aged) population Page 6

  7. OVERVIEW OF DRG GROUPERS MS-DRGs APR-DRGs (3M and NACHRI) Description (CMS - Maintained by 3M) Medicare (age 65+ or under age 65 with disability) All patient (based on the Nationwide Inpatient Sample) Intended Population Intended for use in Medicare Population. Includes 335 base DRGs, initially separated by severity into no CC , with CC or with major CC . Low volume DRGs were then combined. Structure unrelated to Medicare. Includes 314 base DRGs, each with four severity levels. The is no CC or major CC list; instead, severity depends on the number and interaction of CCs. Overall approach and treatment of complications and comorbidities (CCs) Number of DRGs 746 1,256 28 base DRGs, each with four levels of severity (total 112) Newborn DRGs 7 DRGs, no use of birth weight Source: Quinn, K, Courts, C.

  8. OVERVIEW OF DRG GROUPERS MS-DRGs APR-DRGs (3M and NACHRI) Description (CMS - Maintained by 3M) 9 DRGs; most stays group to psychoses 24 DRGs, each with four levels of severity (total 96) Psychiatric DRGs Payment Use by Medicaid (or Moving Toward Use) AZ, CA, CO, FL, IL, KY, MA, MD, MN, MS, MT, ND, NE, NY, OH, PA, RI, SC, TX, WA KS, MI, NC, NH, NM, OK, OR, SD, WI, WV Payment use by other payers Commercial plan use Commercial plan use Hospitals, AHRQ, MedPAC, JCAHO, various state report cards Other users Medicare, hospitals Used as risk adjustor in measuring mortality, readmissions, complications. Can also be used to reduce payment for hospital-acquired conditions. Used as a risk adjustor in measuring readmissions. Used to reduce payment for hospital- acquired conditions. Uses in measuring hospital quality Source: Quinn, K, Courts, C. Sound Practices in Medicaid Payment for Hospital Care. CHCS: November 2010, updated with current information by Navigant. Page 8

  9. OVERVIEW OF DRG GROUPERS What Are Other State Medicaid Programs Doing? APR-DRGs (Using or Moving Toward Use) MS-DRGs (Using or Moving Toward Use) CMS-DRGs AP or Tricare DRGs Per Stay/Per Diem/Cost Reimbursement/Other Page 9

  10. OVERVIEW OF DRG GROUPERS Enhances Homogeneity of Classifications Superior Measurement of Resources Enhances Recognition of Resources Necessary for High Severity Patients Benefits of Migrating to APR-DRGs Enhances Recognition of Acuity Related to Specialty Hospitals, Including Children s and Teaching Hospitals Incorporates Age into Classification Process Critical for Neonatal Cases Facilitates Measurement of Potentially Preventable Readmissions and Complications Reduces Occurrences of Outlier Cases Page 10

  11. OVERVIEW OF DRG GROUPERS MS-DRGs designed for classification of Medicare patients The MS-DRGs were specifically designed for purposes of Medicare hospital inpatient services payment We do not have comprehensive data from non- Medicare payers to use for this purpose. The Medicare program only provides health insurance benefits for people over the age of 65 or who are disabled or suffering from end-stage renal disease. Therefore, newborns, maternity, and pediatric patients are not well represented in the MedPAR data that we used in the design of the MS DRGs. We simply do not have enough data to establish stable and reliable DRGs and relative weights to address the needs of non- Medicare payers for pediatric, newborn, and maternity patients. For this reason, we encourage those who want to use MS-DRGs for patient populations other than Medicare [to] make the relevant refinements to our system so it better serves the needs of those patients.

  12. GUIDING PRINCIPLES AND CONSIDERATIONS FOR DESIGN AND IMPLEMENTATION BY AHCCCS

  13. GUIDING PRINCIPLES AND CONSIDERATIONS Guiding Principles for Evaluating Options Is the option aligned with incentives for providing cost effective care? Cost Effectiveness Does the option promote access to quality care, consistent with federal requirements? Access Does the option promote equity of payment through appropriate recognition of resource intensity and other factors? Equity Resource Recognition Does the option recognize measurable differences in resource requirements? Does the option provide predictable and transparent payment for providers and the State? Predictability Does the option enhance transparency, and contribute to an overall methodology that is easy to understand and replicate? Transparency and Simplicity Does the option promote and reward high value, quality-driven healthcare services? Quality Page 13

  14. GUIDING PRINCIPLES AND CONSIDERATIONS Other Design Considerations Budget Neutrality Funding is not unlimited goal for design is to be budget neutral. Does the option promote adaptability for future changes in utilization and the need for regular updates? Adaptability Forward Compatibility Is the option flexible enough to support payment structures in anticipated future service models? Policy Is the option consistent with State and Federal policy priorities? Page 14

  15. NEW DRG SYSTEM PRICING FORMULAS

  16. NEW DRG SYSTEM PRICING FORMULAS DRG base payment formula ( x ) Provider DRG Transition Multiplier = + Outlier Add- on Payment (If applicable) Claim Payment DRG Base Payment DRG Base Payment = x x DRG Base Rate DRG Relative Weight Policy Adjustor Note: DRG base payment is sometimes reduced on transfer and partial eligibility claims. Page 16

  17. NEW DRG SYSTEM PRICING FORMULAS DRG base rate DRG base rates are based on a statewide standardized amount of $5,295.40 The labor portion of the statewide standardized amount is adjusted by each hospital s Medicare wage index Wage index is a factor that represents differences the relative hospital wage level in the geographic area compared to the national average hospital wage level Example base rate calculation: ($5,295.40 X 0.696 labor portion X 1.0366 wage index) + ($5,295.40 X 0.304 non-labor portion) = 5,430.29 DRG base rate High volume hold harmless adjustment applied to providers who meet specific Medicaid volume criteria and are projected to incur a loss under the new system ADD SPECS Page 17

  18. NEW DRG SYSTEM PRICING FORMULAS DRG relative weights DRG relative weight is a factor that represents the average resource requirements for each DRG DRG relative weight of 1.0 indicates average resource requirements (relative to all other inpatient services) The new system APR-DRG relative weights are based on the National Weights calculated annually by 3M using a national dataset 15 million inpatient claims Example APR-DRG Weight Low weight DRG 640-1 Normal newborn 0.0969 Average weight DRG 225-2 Appendectomy 1.0240 High weight DRG 002-4 Heart transplant 21.2277 Page 18

  19. USE OF POLICY ADJUSTORS Policy adjustor factors Key Medicaid services targeted for enhanced payment to ensure access to care Policy adjustor factors applied to DRG base payments: Normal newborn DRGs: 1.55 factor Neonate DRGs: 1.10 factor Obstetric DRGs: 1.55 factor Psychiatric/Rehabilitation DRGs: 1.65 factor Other pediatric cases (age 18 and under): 1.25 factor Policy adjustor values set at levels for each service to achieve same pay- to-cost ratio as statewide average (including allocated static payments) Exception: Psychiatric/Rehabilitation policy adjustor set to achieve current system spending Page 19

  20. POLICY ADJUSTORS IMPACT Policy adjustor modeled results Policy Adjustor Current System Model Estimated Model Policy Adjuster Estimated Estimated Payment (Based on APR-DRG APR-DRG Case Payment-to- Payment-to- Change Assignment and Age) FFY 2011 Cases Mix Index Cost Ratio Cost Ratio Percentage Neonate 3,988 2.509 70.3% 72.7% 3.4% Normal newborn 42,394 0.123 76.0% 72.9% -4.1% Obstetrics 49,192 0.399 67.0% 72.5% 8.3% Psychiatric/Rehabilitation 890 1.046 69.6% 70.8% 1.8% Other pediatric services 26,474 0.826 65.2% 74.0% 13.6% Other adult services 74,953 1.123 76.8% 72.0% -6.3% Inpatient Total 197,891 0.717 72.5% 72.5% 0.0% Page 20

  21. NEW DRG SYSTEM PRICING FORMULAS Outlier add-on payment formula ( x ) Provider DRG Transition Multiplier = + Outlier Add- on Payment (If applicable) Claim Payment DRG Base Payment ) ( Outlier Add-on Payment (if claim qualifies) DRG Marginal Cost Percentage - x = Claim Cost Outlier Threshold Note: Outlier payments are only applied if claim cost is greater than the outlier threshold. Page 21

  22. NEW DRG SYSTEM PRICING FORMULAS Outlier add-on payment components Outlier add-on payment made for extraordinary cost cases where the claim cost exceeds the outlier threshold for a DRG Outlier threshold equal to the base DRG payment plus the fixed loss threshold Provider must incur a fixed loss on the claim for costs exceeding the base DRG payment Fixed Loss Amount is $5,000 for Critical Access Hospitals (CAH)/small rural providers and $65,000 for all other providers. Outlier add-on payment calculated as the cost exceeding the outlier threshold, multiplied by the DRG marginal cost percentage DRG marginal cost percentage is 90% for burn DRGs and 80% for all other DRGs Page 22

  23. NEW DRG SYSTEM PRICING FORMULAS Transition adjustment factor formula ( x ) Provider DRG Transition Multiplier = + Outlier Add- on Payment (If applicable) Claim Payment DRG Base Payment Documentation and Coding Improvement Factor Provider DRG Transition Multiplier x Transition Impact Factor = Note: Outlier payments are only applied if claim cost is greater than the outlier threshold.

  24. NEW DRG SYSTEM PRICING FORMULAS Provider DRG transition multiplier components Transition adjustment factor is a temporary (first two years only) provider-specific factor that limits the payment gain or loss under the new system based on the payment simulation model Year 1 factor limits the gain or loss to 33% of the full estimated gain/loss Year 2 factor limits the gain or loss to 66% of the full estimated gain/loss Documentation and coding improvement factor is a statewide factor that is a preemptive adjustment for an expected 3 percent increase in DRG case mix over real case mix increases as a result of improved documentation and coding under the new system 0.9739 factor in Year 1 Adjustments in future periods may depend on actual trends Page 24

  25. NEW DRG SYSTEM PRICING FORMULAS Transfer payment formula Claim payment where an acute patient is transferred to another hospital is pro-rated based on claim length of stay Transfer payment cannot exceed the full DRG base payment ) ( DRG National Average Length of Stay Claim Length of Stay +1 x Transfer DRG Base Payment= / DRG Base Payment Page 25

  26. AHCCCS DRG PRICING MODEL

  27. AHCCCS DRG PRICING MODEL New system DRG payment simulation DRG pricing model simulates payments under the new DRG system, including the DRG base payment, outlier payment and policy adjusters, using historical claims data Model used to establish what the DRG base rates can be given all other payment methodology parameters, while maintaining budget neutrality Model also compares simulated payments under the new system to payments under the current system and estimated provider costs, at the following levels: Provider level Service line level System aggregate Page 27

  28. AHCCCS DRG PRICING MODEL Standardized amount determination DRG pricing model is based on FFY 2011 Arizona Medicaid FFS claims and managed care encounter data and Medicare cost report data for in- state providers and critical out-of-state providers Funding pool for determination of budget neutrality is based on FFY 2011 model claim/encounter total reported payments, with reductions applied to reflect payment rate/methodology changes since 2011 DRG base rates solved for to be budget neutral to current system payments DRG base rates result in aggregate simulated DRG payments that are approximately equal to FFY 2011 aggregate adjusted reported payments Page 28

  29. POLICY ISSUES

  30. POLICY ISSUES ENROLLMENT CHANGE DURING HOSPITAL STAY Recipient may change payers during a single hospital stay, while maintaining Medicaid eligibility throughout entire stay This may occur under a variety of scenarios including Enrollment change from fee-for-service to managed care plan Enrollment change from managed care plan to fee-for-service Enrollment change between managed care plans within the same program Enrollment change between managed care plans in different programs, for example moving from an Acute MCO to the Arizona Long Term Care System (ALTCS) Services paid via DRG method will be paid by the payer to which the recipient is enrolled at the date of discharge Providers to submit a claim to the appropriate payer Page 30

  31. POLICY ISSUES MEDICARE PART A BENEFITS EXHAUSTED In the event recipient exhausts Medicare Part A benefits during a single hospital stay, providers must submit a second claim for the Medicaid covered portion of the stay A full DRG payment will be paid for the Medicaid claim Page 31

  32. POLICY ISSUES ADMINISTRATIVE DAYS AHCCCS may offer reimbursement for Medicaid recipients occupying a bed while not in need of care These days are referred to as administrative days Administrative days must be prior authorized by AHCCCS Administrative days will be reimbursed using a negotiated per diem rate Reimbursement for administrative days will be separate from DRG reimbursement for acute care services and provider must bill such days on a separate claim Page 32

  33. POLICY ISSUES INTERIM CLAIMS A recipient may be in the hospital for an extended period of time If patient stay exceeds a 29 day period, hospitals may submit interim claims related to the patient stay in increments of 30 days Interim claims will be reimbursed under a per diem rate of $500 per day Hospitals must submit a final claim associated with the patient stay upon the patient s discharge all previously submitted interim claims will be voided and final claim will be paid Page 33

  34. POLICY ISSUES RECIPIENT GAINS ELIGIBILITY AFTER ADMISSION A recipient may be ineligible for Medicaid upon admission, however, may become eligible for Medicaid during the hospital stay Providers will be reimbursed for the Medicaid covered days of the hospital stay The DRG payment designed to cover the full hospital will be prorated based on the number of Medicaid covered days This prorated payment to providers will not exceed the full DRG payment Only claims with dates of service where the recipient is an eligible member will be accepted Page 34

  35. POLICY ISSUES RECIPIENT LOSES ELIGIBILITY PRIOR TO DISCHARGE A recipient may be eligible for Medicaid upon admission, however, may lose eligibility for Medicaid prior to being discharged Providers will be reimbursed for the Medicaid covered days of the hospital stay The DRG payment designed to cover the full hospital will be prorated based on the number of Medicaid covered days This prorated payment to providers will not exceed the full DRG payment Only claims with dates of service where the recipient is an eligible member will be accepted Page 35

  36. POLICY ISSUES SAME DAY ADMISSION AND DISCHARGE A recipient may be admitted and discharged on the same day Inpatient claims with a date of admission matching the date of the discharge will be paid under the reimbursement policy that is currently in place for AHCCCS, with one exception. Maternity and nursery claims will be reimbursed under the AHCCCS Outpatient Hospital Fees Schedule Methodology (OPFS) Page 36

  37. POLICY ISSUES HEALTH CARE ACQUIRED CONDITIONS (HCAC S) For claims paid via DRG methodology, AHCCCS will utilize DRG assignment to determine payment reductions in cases of health care acquired conditions A present on admission (POA) indicator will continue to be required on all inpatient claims as the HCAC payment reduction policy only applies if the HCAC condition(s) were acquired in the hospital after admission Under the DRG methodology, two DRGs will be assigned to every claim ( pre-HCAC and post-HCAC ). The DRG will the lower relative weight will be used to price the claim. Page 37

  38. POLICY ISSUES READMISSION POLICY A recipient may be readmitted to a hospital after receiving a service or treatment For claims paid under DRG methodology, the Administration will identify certain readmission cases and conduct a medical review to determine if the readmission was preventable by the hospital The following criteria will prompt a medical review Recipient is readmitted to the same hospital within 72 hours, and The base DRG assignment on the readmission claim must match the base DRG assignment on the initial claim, and The readmission claim has not been prior authorized Page 38

  39. POLICY ISSUES READMISSION POLICY Claims which meet the criteria described, will be pended for medical review The payment associated with the readmission claim will be held until the completion of the medical review process If the claim is determined to have been preventable by the hospital, the payment associated with the readmission claim will be disallowed Alternatively, if upon the medical review it is determined the hospital would not have been able to prevent the readmission, the claim will be paid under DRG methodology Page 39

PRICING EXAMPLE FINAL REIMBURSEMENT AMOUNT The Final Reimbursement Amount will be calculated as: Final Reimbursement Amount = Final Allowed Amount - Other Insurance Payment + / - Prompt Pay Adjustment Note: The current prompt pay policy (slow pay penalties and quick pay discounts) will continue to apply.

  48. DOCUMENTATION AND CODING IMPROVEMENT

  49. DOCUMENTATION AND CODING IMPROVEMENT The Need for a Documentation and Coding Adjustment: Documentation and Coding Improvement (DCI) is necessary, and as such are expected to be made by providers as an appropriate response to the coding requirements under the APR-DRG model Because the same level of coding rigor was not required for payment purposes under the legacy per diem model, AHCCCS expects that case mix will increase as a result of DCI coding once the system is implemented beyond actual increases in acuity To maintain budget neutrality, it will be necessary to incorporate an adjustment to offset increases in case mix after implementation AHCCCS expects that actual payments, in the aggregate, will be greater than simulated amounts, and as such, resulting actual payments will remain budget neutral Page 49

  50. DOCUMENTATION AND CODING IMPROVEMENT Preemptive adjustment Up-front 3 percent adjustment for expected Documentation and Coding Improvement (DCI) Simulate a 3% casemix increase and determine an adjustment factor ( DCI Factor ) that would be necessary to maintain budget neutrality Claim allowed amounts (including the base DRG payment, outlier payment or transfer payment) will be reduced by the DCI factor With a 3% casemix increase, the DCI factor is 0.974 Page 50
