SC HealthViz Definition of Key Terms

June, 2017 Data Tables:

Source Data: Data were pulled using IBM Corporation, Truven Health Analytics Inc., Advantage Suite® Version 3.0.3-850, Adhoc Report Writer. Enrollment and demographic information were derived from the SC Medicaid Management Information System (MMIS). The MMIS is an integration of computer systems that work together to process Medicaid claims and other pertinent information related to the management of the SC Medicaid Program. Note: After the implementation of the Affordable Care Act, changes in the way race information is collected and reported in the system has resulted in a greater proportion of missing race and county demographic information during recent years. 

Enrollment Notes: These data are current as of June 15, 2017 and have been separated into two categories, full and limited benefits. To minimize duplication, the year represents data for one incurred month during each state fiscal year. Duplication may still exist; as such, do not sum subtotals to obtain total membership. Caution should be taken when comparing preliminary 2016 enrollment to prior years. Due to recent changes in the SC Medicaid managed care program, the presentation of data is as of 2013. Eligibility definitions may shift from year to year, accounting for differences in current data to archived. 

Benefits & Services Notes: These data are current as of June 15, 2017 and represent claims paid through May 31, 2017. The year represents data for the state fiscal year (July 1 – June 30). These data do not account for 90 days of retroactive eligibility. Although generally administrative claims or enrollment data is of high quality, some issues with these data may exist due to miscoding or misclassification. Aggregate totals by demographic or plan type may not match overall totals due to confidentiality rules being applied, missing values, or the fact that some members may be represented in more than one category in a single fiscal year, such as having lived in two counties. 

Confidentiality Rules: Benefits and services data with a value of less than 10 do not provide sufficient information to ensure the health information privacy of SC DHHS Medicaid clients; therefore, these data were rolled up to 10.
