MassHealth Prior (Rx) Authorization Form

Updated June 02, 2022

A MassHealth Prior Authorization Form is used by a medical office when they wish to request coverage from MassHealth for a prescription not listed on the formulary on behalf of a patient. This action is usually taken when other medications have been unsuccessful in treating their patient for a particular diagnosis. By filling and submitting this form, the medical professional may be able to secure coverage of a particular prescription for their patient.
