History of Enrollment or Denominator Information for use in Part D studies Until recently there was a single Denominator File created originally to work with Part A and Part B data; thin (80 columns), and we suggested that everyone get a copy of it for every study. Now different denominator files may be mentioned: The old Denominator File is no longer available The Part D Denominator short lived Beneficiary Summary File (BSF) the next one Master Beneficiary Summary File (MBSF) -- this is it! (for now) 5
Master Beneficiary Summary File Segments There are 4 segments to the Master Beneficiary Summary File Beneficiary Summary File or Medicare Enrollment (A/B/C/D information) Chronic Conditions Cost & Utilization NDI Death Information (includes ICD-10 Cause of Death) ; through 2008. This presentation is about the Beneficiary Summary File (BSF) segment; sometimes shown as Part A/B or Part A/B/D 6
Beneficiary Summary File (BSF) Segment of the MBSF Similar to the traditional Medicare Denominator File 100% of all Medicare beneficiaries enrolled in that year Annual, calendar year file one record per beneficiary Information is what is known by CMS as of 12/31/20XX Traditional denominator information available by end of summer of 20XX+1 in what is now called the Beneficiary Summary File (BSF) segment of the MBSF Part D denominator information added in January or February/March 20XX+2, also, to the BSF segment of the MBSF So, you could have received the BSF segment for one year in 1 or 2 pieces depending on when you request data. May not be true in 2013 and forward. 7
Traditional Demographic and Enrollment Information in BSF Segment of MBSF Unique beneficiary identification number Demographics Medicare Part A, Part B, and Medicare Advantage Plan enrollment information by month and annually Information about death Died during that year (yes/no) Date the person died Whether the beneficiary is in the 5% CCW random sample or the enhanced 5% CCW random sample Note: Part D data, unless otherwise specified in the Data Use Agreement (DUA) will be on the 5% samples 8
Identification Number and Demographic Information A beneficiary identification number: encrypted BENE_ID is unique to each Data Use Agreement (DUA); created by CCW/Buccaneer Date of birth and Age as of 12/31/20XX Gender Race/ethnicity a one column field Place of residence state, county and zip code 9
Agreement Between Demographic Information in BSF and in Claims Files All demographic information in BSF and claims files comes from the Enrollment Database (EDB) maintained at CMS Data Center As claims are processed, the demographic information known to CMS at that time overwrites any demographic information in the claim Therefore, there is agreement between BSF and claims unless change in status during the year essentially talking about change in residency PDE File gender and date of birth variables from a different source; therefore, recommend linking PDE and BSF for all demographic information. 10
Residency in BSF State, county and ZIP code of residence are the mailing address for official correspondence Some persons have their mail sent to another person (e.g., son, daughter, guardian) Because residency in BSF is based on the information available at the end of the calendar year, there may be some mismatch with residence on a claim from earlier in year. No residency variables in PDE or other Part D data files. 11
Traditional Enrollment Information A variable for each month and one indicting the total number of months enrolled in that year Enrolled in Medicare Part A Enrolled in Medicare Part B State buy-in did a state pay Medicare for beneficiary s Part B coverage in traditional Medicaid Program or in a Medicare Savings Program (QMB, SLMB, QI) Enrolled in Medicare Advantage (Part C); a.k.a. managed care, HMO 12
Medicare Savings Programs http://www.medicare.gov/publications/pubs/pdf/10126.pdf http://www.medicareinteractive.org/page2.php?t opic=counselor&page=script&slide_id=390 and link to the individual state requirements New York state (see handout in this tab) - http://www.health.ny.gov/health_care/medicaid/program /update/savingsprogram/medicaresavingsprogram.htm QMB Qualified Medicare Beneficiary SLIMB Specified Low-income Medicare Beneficiary QI Qualifying Individuals QDWI Qualified Disabled and Working Individuals 13
State Buy-in Variable Values 0 = NOT ENTITLED 1 = PART A ONLY 2 = PART B ONLY 3 = PART A AND PART B A = PART A, STATE BUY-IN B = PART B, STATE BUY-IN C = PARTS A AND B, STATE BUY-IN 14
State Buy-In Indicator Values, June 2008 5% Sample, all ages State Buy-In Frequency Percent 0 = Not entitled (Why?) 126,068 4.82 1 = Part A only 164,463 6.28 2 = Part B only 3,826 0.15 3 = Part A and Part B 1,913,210 73.07 A = Part A, State Buy-in 58 0.00 B = Part B, State Buy-in 13,603 0.52 C = Parts A & B, State Buy-in 396,942 15.16 15
How ResDAC Recommends You Use the State Buy-In Variable 1. Use it to select those with both Part A and Part B coverage State Buy-in Variable values of 3 and C Do all of your studies on those who have both Part A and Part B coverage. Why? see next slide» Those with Part A only have lower rates of utilization (of hospitalization, e.g.» Not many beneficiaries with only Part B, and probably have different health utilization patterns 2. To identify those with less resources (will discuss in Segments C and D of this workshop) 16
Hospitalization rates by type of Medicare coverage (per 100 enrollees) supports the conclusion that persons with A-only coverage probably have incomplete claims, even for Part A services 35 30 25 20 15 10 A+B A only 5 0 65-74 75-84 85+ 17
Part D-related Denominator and Enrollment Information in the BSF Segment of the MBSF Types of information RTI race variable (RTI = Research Triangle Institute) Additional enrollment information Information for linking with the Part D Characteristics Files Enrollment information is presented in 2 different ways For each month of the year; therefore, 12 variables Number of months (0-12), 1 variable 18
Race A One Column Variable Hispanic ethnicity not asked nor coded separately Originally, race coded as: white, black, other, unknown Effective 1994, race codes were expanded to: white, black, Asian, Hispanic, Native American, other, unknown the old race variable. New RTI Race Code variable is available in the Beneficiary Summary File segment of the Master Beneficiary Summary File (The old race code information is available, also.) Was in the Part D sub-segment, but now in the Part A/B subsegment. 19

Extra help Low Income Subsidy (LIS) Benefits Help paying Medicare drug plan s monthly premium, any yearly deductible, coinsurance, and/or copayments No coverage gap liability No late enrollment penalty Major Effort on the part of CMS and advocacy groups to inform beneficiaries about the Low Income Subsidy available to them to help pay for Part D services. Low Income Subsidy (LIS) only relates to Part D services, but this information is known for all beneficiaries 27
Extra Help Low Income Subsidy - Repeat Repeat: Major Effort on the part of CMS and advocacy groups to inform beneficiaries with incomes and/or assets above levels that would qualify them for the above programs about the subsidy(ies) available to beneficiaries to help pay for Part D services Medicare & You 2013 - http://www.medicare.gov/pubs/pdf/10050.pdf National Council on Aging - http://www.ncoa.org/assets/files/pdf/center-forbenefits/part-d-lis-eligibility-and-coverage.pdf http://www.ncoa.org/assets/files/pdf/center-forbenefits/part-d-lis-eligibility-and-benefits-chart.pdf See handout at end of this tab for next 2 slides 28

State Reported Dual Status Eligible Code Variable Occurs 12 times Can finally tell who has traditional Medicaid versus one of the Medicare Savings Programs (QMB, SLMB, QI, QDWI). As described earlier, formerly, the Medicare Denominator File and the BSF only had a State buy-in variable that lumped together Medicaid recipients and those in Medicare Savings Programs (QMB, SLMB, QI, QDWI). 40
State Reported Dual Eligible Status Code Variable Values 00 = Not Medicare enrolled for the month XX = Enrolled in Medicare A and/or B, but no MIIR record for the month NA = Non-Medicaid 01 = QMB only 02 = QMB and Medicaid coverage including RX 03 = SLMB only 04 = SLMB and Medicaid coverage including RX 05 = QDWI 06 = Qualified Individuals 08 = Other Dual Eligibles (Non-QMB, SLMB, QWDI, or QI) w/medicaid coverage including RX 09 = Other Dual Eligibles but without Medicaid coverage 99 = Unknown 41
