National Review of Opioid Prescribing in Medicaid Is Not Yet Possible

Historically, national Medicaid data—a collection of data submitted by all States—have not been complete, accurate, and timely. These data have not yet been adequate for national analysis and oversight, even though some States' data have been sufficient for individual State analysis. Because of concerns with the quality and completeness of the national Medicaid claims database-the Transformed Medicaid Statistical Information System (T-MSIS)-we assessed the completeness of variables needed to monitor national opioid prescribing in Medicaid.
