The magnitude of case-mix adjustments, the effects of adjustments on plan rankings, and the homogeneity of these effects across plans were examined.<bold>Data Extraction: </bold>All ratings and reports were linearly transformed to a possible range of 0 to 100 for comparability.<bold>Principal Findings: </bold>Case-mix adjusters, especially self-rated health, have substantial effects, but these effects vary substantially from plan to plan, a violation of standard case-mix assumptions.<bold>Conclusion: </bold>Case-mix adjustment of CAHPS data needs to be re-examined, perhaps by using demographically stratified reporting or by developing better measures of response bias.
