Medicaid Issue Briefs

What’s New in September 2013!

  • A new issue brief is now available titled “Home- and Community-Based Service Use Among Medicare-Medicaid Enrollees with Functional Limitations, 2007–2008.”  This issue brief presents the results of the first study conducted using data from MAX and the Medicare Current Beneficiary Survey (MCBS).  In the study, we assessed the use of home- and community-based services (HCBS) by the presence and level of functional limitations, as measured by limitations in activities of daily living (ADL).  We illustrated that these limitations appear to be common among Medicare-Medicaid enrollees and affect both the percentage of enrollees who use HCBS and the cost associated with that care.  This issue brief is available through the links in the “Downloads” section.

What’s New in August 2013!

  • A new issue brief is now available titled “The HCBS Taxonomy:  A New Language for Classifying Home and Community-Based Services.”  Because state Medicaid programs differ in the types of services they offer and in how they report these services in their data, analyzing HCBS at the national level has been challenging.  With the development of the HCBS taxonomy—a uniform classification system composed of 18 categories and over 60 services—states and CMS now have a common language for describing and categorizing community-based long-term care services.  This issue brief describes the HCBS taxonomy and presents findings on HCBS expenditures and service use for the 28 states in MAX 2010 that were approved for this analysis.  The issue brief is available through the links in the “Downloads” section below.  The HCBS taxonomy and the detailed HCBS crosswalk, which maps services into the HCBS taxonomy, are available through the MAX 2010 link in the “Downloads” section of the MAX General Information page.

What’s New in June 2013!

  • A new issue brief is now available titled, “Implications of State Methods for Offering Personal Assistance Services.”  This article examines the differences in the use and cost of personal assistance services in states that do and do not provide these services through their state plans. States that offer these services through their state plans appear to provide them to a greater number of beneficiaries at a lower cost per beneficiary than states that do not. These states also have long-term care systems that are more balanced toward home- and community-based rather than institutional long-term care services.  The issue brief is available through the links in the “Downloads” section.

What’s New in March 2013!

  • A new issue brief is now available titled “Trends and Patterns in the Use of Prescription Drugs Among Medicaid Beneficiaries: 1999 to 2009.”  This issue brief highlights the changes in volume of drugs used per person, changes in drug costs per person, and changes in the use of generic drugs between 1999 and 2009.  The analysis focuses in particular on drug use and costs for beneficiaries with disabilities and chronic illnesses, whose drug use is much more extensive than that of children and nondisabled adults.  It also focuses on some specific types of drugs that are especially costly for Medicaid:  antipsychotics, antiasthmatics, ulcer drugs, antidiabetics, and antidepressants. The issue brief is available through the links in the “Downloads” section.

What’s New in January 2013!

  • A new issue brief is now available titled “Using the MAX-NHANES Merged Data to Evaluate the Association of Obesity and Medicaid Costs.”  This issue brief presents the results of the first study conducted using the newly merged MAX-NHANES data. Using data from MAX-NHANES 1999-2004, we assessed the association of obesity on annual total fee-for-service Medicaid costs. While the estimated costs were higher for obese adults than non-obese adults, the differences in costs by obesity status were not significant at the 0.05 level. The results of the analysis demonstrate the hazard of using a small national survey (NHANES) with a state-based data system (MAX) to perform cost analyses, particularly when the range of realistic costs is large.  This issue brief is available through the links in the “Downloads” section.

What’s New in December 2012!

  • A new issue brief is now available titled “Assessing the Usability of Encounter Data for Enrollees in Comprehensive Managed Care Across MAX 2007–2009”.  This issue brief assesses the availability, completeness, and quality of encounter data in MAX 2007–2009.  The analysis builds on our previous reviews of MAX 2007 and 2008 encounter data by evaluating MAX 2009 physician, outpatient, and clinic services (OT), inpatient hospital services (IP), and prescription drug services (RX), and by assessing trends in the availability and usability of encounter data across the three year period.  The analysis provides tools to assist researchers and policymakers in determining which states’ encounter data to analyze.  The increase in reporting and usability makes the inclusion of encounter data in research studies a more viable option than in the past.  This issue brief is available through the links in the “Downloads” section.
  • A new issue brief is now available titled “The Availability and Usability of Behavioral Health Organization (BHO) Encounter Data in MAX 2009”.  The purpose of this issue brief is to provide a detailed analysis of the behavioral health organization (BHO) encounter data in MAX 2009 and assess the viability of using these data for research and policy analysis.  This issue brief is available through the links in the “Downloads” section.

What’s New in November 2012!

  • A new issue brief is now available titled “CHIP Data in the Medicaid Statistical Information System (MSIS): Availability and Uses.”  This issue brief discusses the increasing availability of Children’s Health Insurance Program (CHIP) data in the Medicaid Statistical Information System (MSIS) and potential uses for that data, including to monitor program performance, evaluate policy options, and help implement provisions of the Affordable Care Act (ACA).  It is available through the links in the “Downloads” section.
  • A new issue brief is now available titled “Best Practices for Linking Medicaid and Separate CHIP Eligibility Records.”  This issue brief provides guidance to states that have distinct eligibility determination systems for Medicaid and separate CHIP on how to link enrollment records across systems and report a unique, permanent identifier to MSIS.   It is available through the links in the “Downloads” section.

What’s New in October 2012!

  • Two new issue briefs are now available.  The first is titled “Utilization of Dental Services among Medicaid Enrolled Children.”   It includes an estimate of current rates of utilization for dental services among Medicaid-enrolled children in nine states and then evaluates how a child’s personal and community characteristics impact the likelihood that they utilize dental services.  The second is titled “Utilization of Well-Child Care among Medicaid Enrolled Children.”  It includes an estimate of current rates of utilization for well-child care among Medicaid-enrolled children in nine states and then evaluates how a child’s personal and community characteristics impact the likelihood that they utilize well-child services. These issue briefs demonstrate the use of Mini-MAX (MAX sample data) for research and demonstrate that Mini-MAX can produce useful analyses for policy makers.  Please see the “Downloads” section below.  
  • A new issue brief is now available titled “Physician Service Use and Participation in Medicaid, 2009.”  This issue brief presents an analysis of physician use and participation using the 2009 MAXPC data, Area Resource File (extracted from the American Medical Association master file), and National Plan and Provider Enumeration System data.  The analysis focuses on four major topic areas:  (1) the number of physicians serving Medicaid enrollees and average physician caseload, (2) the distribution of Medicaid physician caseload by physician, (3) enrollees served by in-state and out-of-state physicians, and (4) physician participation rates in Medicaid.  It is available through the links in the “Downloads” section.

Description

During this time of rapid health reform, researchers and policymakers want access to the latest information on Medicaid enrollment, expenditures, and service use. They also want reports that are shorter, more focused, and more relevant to today's challenges facing the Medicaid program. CMS, in collaboration with Mathematica, has started the MAX Medicaid policy issue brief series, which highlights the essential role MAX data can play in analyzing the Medicaid program.
