Abstract
This study reviews Medicaid policies to restrict access to psychiatric medications. Policies on prior authorization, preferred drug lists, limitations on the number of prescriptions, fail-first requirements, and use of generics are reviewed. All states apply one or more of those policies to medications for mental illness, and many apply several. A large number of states have legislated exemptions from those policies for certain medications, particularly antipsychotics and antidepressants. Other psychiatric medications are less well protected. Some states appear to restrict access severely. Questions have been raised as to whether these policies actually save money in the long term.
