This data set includes monthly counts and rates (per 1,000 beneficiaries) of vaccinations provided to Medicaid and CHIP beneficiaries under age 19 (as of the first day of the month), by state. The following vaccinations are included: Chickenpox, DTaP, HPV, Hepatitis A, Hepatitis B, Influenza, MMR, Meningococcal, Meningococcal B, Pneumococcal conjugate, Pneumococcal polysaccharide, Polio, Rotavirus, Tdap, and all vaccinations.

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 vaccination measures. To assess data quality, analysts adapted measures featured in the DQ Atlas. Data for a state and month are considered unusable if at least one of the following topics meets the DQ Atlas threshold for unusable: Total Medicaid and CHIP Enrollment, Procedure Codes - OT Professional, Claims Volume - OT. Please refer to the DQ Atlas at http://medicaid.gov/dq-atlas for more information about data quality assessment methods. Cells with a value of “DQ” indicate that data were suppressed due to unusable data.

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

State-reported data on Medicaid and CHIP eligibility renewals that reflect the outcomes of previously pending renewals three months after the renewal was due and also any corrections to the original renewal data submitted to CMS. See here for original renewal data.

CMS renewal data specifications require states to update and submit to CMS their monthly renewal outcome metrics - metric 5 data and its submetrics (monthly metrics 5a, 5a(1), 5a(2), 5b, 5c, and 5d) - after the original monthly report submission. The “updated” renewal data reflect the outcomes of renewals previously reported as pending (monthly metric 5d of the original monthly report) as of three months after the renewal was due. For more information about this data set and considerations for users when reviewing, please see the Medicaid and CHIP Unwinding: Data Sources and Metrics Definitions Overview found here.
