ASSESSMENT OF OVERALL DATA QUALITY AND COMPLETENESS

*INDIANA* 1999 TABLES

Nine tables for each State show the use of mental health and other
services by Medicaid beneficiaries with mental health diagnoses in 1999.
Enrollment and claims data from the Medicaid Analytic eXtract (MAX)
files from the Centers for Medicare & Medicaid Services (CMS) are the
source for these analyses. Because Medicaid programs differ across the
States, and because administrative data vary in completeness and
quality, caveats about the State's data should be considered in
interpreting the information contained in these tables.

  **Indiana Data Comments**
  -----------------------------------------------------------------------
  **Managed Care:** Many individuals are enrolled in fee-for-service
  Medicaid for at least one month, even if they eventually become managed
  care enrollees; these individuals, and utilization during their FFS
  months, appear on Tables 2 - 9.

  **Diagnosis Codes:** Diagnosis coding on claims was relatively
  complete, with no known quality problems.

  **Inpatient Days:** Indiana's inpatient crossover claims rarely
  included covered days. This causes inpatient hospital stays for groups
  of Medicaid beneficiaries that include a high proportion of dual
  eligibles (most aged and many disabled beneficiaries) to average "1"
  day in length, and explains the other low numbers that appear for some
  groups on Table 4.
