Notes
Data include individuals ages 19-64 who received full Medicaid benefits for at least one month during the calendar year. These data exclude Medicaid enrollees who also have Medicare.
Chronic condition counts used the CCW algorithm for identifying chronic conditions (updated in 2020). This analysis also included in its definition of chronic conditions substance use disorder, mental health, obesity , HIV , hepatitis C, and intellectual and developmental disabilities . In total, 35 chronic conditions were included. See 5 Key Facts About Medicaid Coverage for Adults with Chronic Conditions for methods and more information.
Claims data reflect only diagnoses recorded during medical visits and do not measure overall prevalence. Prevalence rates from surveys are generally higher than claims-based estimates because not everyone is screened, treated, or has a recorded diagnosis for their chronic conditions in claims data in any given year.
Enrollment data are rounded to the nearest 100. State totals may not sum to national total due to rounding.
States with "Unusable" data quality according to the CMS DQ Atlas indicators "Medicaid-Only Enrollment", "Claims Volume - OT", "Claims Volume - IP", "Claims Volume - LT" and "Claims Volume - RX." are not included in these tables and are not included in national totals. For more information on data quality issues that may lead to unusual spending or enrollment, see CMS DQ Atlas. Caution is recommended when comparing data between years since different states may be included in each year due to data quality.
