PPRs and Mental Health  Readmissions for mental health conditions are treated no differently, from a preventability point of view, than any other chronic condition such as diabetes.  For example, all patients who have diabetes and are readmitted for virtually any chronic medical condition (e.g. CHF) are considered to have had a preventable readmission

The Actual To Expected Calculation IS Different for Mental Health/ Substance Abuse Services  The Actual To Expected calculation is adjusted for the presence/absence of principal and/or secondary diagnoses of MH/SA.  The reason is that patients with mental health conditions in the initial admission historically have had higher rates of readmissions.  Those institutions that take on larger numbers of MH/SA patients will have greater protection because the A/E computation adjustment takes into account the higher rates of readmissions for patients with significant MH/SA conditions.
