Dual Status Information for Medicaid and CHIP Beneficiaries by Year

This data set presents annual enrollment counts of Medicaid and CHIP beneficiaries by dual eligibility status for Medicaid and Medicare (full dual eligibility, partial dual eligibility, or not dually eligible). There are three metrics presented: (1) the number of beneficiaries ever dually eligible for Medicaid and Medicare over the year (duplicated count); (2) the number of beneficiaries dually eligible for Medicaid and Medicare as of an individual’s last month of enrollment (unduplicated count); and (3) average monthly eligibility for Medicaid and Medicare.

These metrics are based on data in the T-MSIS Analytic Files (TAF). Some states have serious data quality issues for one or more months, making the data unusable for calculating these measures. To assess data quality, analysts adapted measures featured in the DQ Atlas. Data for a state and month are considered unusable or of high concern based on DQ Atlas thresholds for the topic Dually Enrolled in Medicare. Please refer to the DQ Atlas at http://medicaid.gov/dq-atlas for more information about data quality assessment methods.

Some cells have a value of “DS”. This indicates that data were suppressed for confidentiality reasons because the group included fewer than 11 beneficiaries.

本数据集展示了按双重资格状态（包括全面双重资格、部分双重资格或非双重资格）划分的Medicaid和CHIP受益人年度注册人数。数据集包含三个指标：（1）全年内曾双重符合Medicaid和Medicare资格的受益人数（重复计数）；（2）截至个人最后一个月注册时双重符合Medicaid和Medicare资格的受益人数（不重复计数）；以及（3）Medicaid和Medicare的平均月资格人数。这些指标基于T-MSIS分析文件（TAF）中的数据。部分州在一个月或几个月内存在严重的数据质量问题，导致无法计算这些指标。为了评估数据质量，分析师采用了DQ Atlas中的指标。如果一个州和月份的数据根据DQ Atlas中关于Medicare双重注册主题的阈值被认为不可用或高度关注，则该数据被视为不可用。请参阅http://medicaid.gov/dq-atlas以获取有关数据质量评估方法的更多信息。某些单元格的值为“DS”，这表示由于包含的受益人少于11人，出于保密原因对数据进行压制。
