Findings (3)

Each finding has a stable link.

  1. F-1417

    CMS performed only limited accuracy checks on the four required MLR data elements, and those checks showed that some State-submitted MLR data may be inaccurate.

  2. F-1418

    CMS did not follow up with States that submitted potentially inaccurate MLR data.

  3. F-1419

    Results of MLR accuracy checks were not shared across CMS staff, limiting the ability to inform capitation-rate reviews.

Recommendations (3)

  1. R-1274

    CMS should establish procedures that outline the steps to be taken to address potentially inaccurate Medicaid MLR data submitted by States and follow up with States, as needed.
