Effective April 1, 2008, Medicaid requires all written prescriptions to be on tamper-resistant presciption pads. Prescriptions submitted via fax, e-prescribing, or telephone are exempt from the requirements, as are prescriptions in long-term care facilities and hospitals.

·  CMS' guidance on the tamper-resistant law, set forth in an August 17, 2007 State Medicaid Director letter, contains two phases.  For the first, a prescription must contain at least one of the three tamper-resistant characteristics in order to be considered "tamper resistant."  For the second, prescriptions must contain all three characteristics.
