Review of Existing Data Sources to Assess the Impacts of the Affordable Care Act Medicaid Expansions: Working Paper. STATE POLICY CHOICES

04/01/2012

The Affordable Care Act's impacts on individuals and providers will be influenced by states' policy choices, such as decisions about Medicaid benefit levels, outreach strategies, and provider reimbursement rates. Table 13 presents a list of key policy choices that will be important to track in order to understand how states' decisions are influencing the Affordable Care Act's impacts on individuals and providers. The table also includes ongoing data sources that track the relevant information, to the degree that they currently exist.

In some cases, the variables of interest relate to specific policy decisions that states must make to implement the Affordable Care Act. For example, states will need to decide what benefits are covered in Medicaid benchmark plans and whether to establish a Basic Health Plan. Because these decisions will be made in the future, no existing data source describes them. This information could be obtained by modifying existing data sources (see below) or through new data collection. Much of this information will be available to CMS through states' amendments to their Medicaid state plans; in addition, the Affordable Care Act specifically requires states to report to the Secretary of Health and Human Services (HHS) each year on their outreach activities. It would be helpful if this information were reported in a standardized way that can be easily accessed by the evaluation team.

For the policy variables where data are currently available, the data come from several sources. The first of these sources is existing HHS public reporting. For example, data about Medicaid managed care is currently available through CMS Medicaid Managed Care Enrollment Reports, and HHS already publishes information about Federal Medical Assistance Percentagesand Disproportionate Share Hospital Allotments. A second major source of existing data about state policy decisions is the annual 50-state survey conducted by the Kaiser Commission on Medicaid and the Uninsured and the Georgetown University Center for Children and Families.12 This survey collects detailed information about Medicaid eligibility rules, enrollment and renewal procedures, and cost-sharing practices. Finally, information about the numbers of health care providers by type is available from various sources, including the AHA annual survey and AMA Physician Masterfile described earlier in this report; these provider data are also available aggregated to the county level through the Area Resource File (ARF) made available by HRSA, although the ARF data are not available in as timely a way as the source data. Similar to the ARF, CMS's Environmental Scanning and Program Characteristics (ESPC) Database aggregates state-level information from a variety of sources on the characteristics of state Medicaid programs and a variety of other factors from existing publicly available data sources. An advantage of the ESPC database is that it aggregates relevant information into a single database; a disadvantage, however, is that it lags behind the availability of the source data.
