Final answer:
Federal law requires tamper-resistant forms for outpatient Medicaid prescriptions to prevent duplication, erasure/modification, and counterfeit forms.
Step-by-step explanation:
Federal law requires that a tamper-resistant form be used for outpatient Medicaid prescriptions. This is to ensure the safety and security of the prescriptions and prevent duplication, erasure/modification, and counterfeit forms.
An example of a feature that prevents duplication is the appearance of the word 'VOID' when the prescription is photocopied. An example of a feature that prevents erasure/modification is the use of special ink that cannot be altered. And an example of a feature that prevents counterfeit forms is the use of unique watermarks and security features.
In addition, some states also require tamper-resistant security forms for prescriptions written for schedule II drugs, all controlled substances, or for all drugs in order to further protect against fraud and ensure patient safety.
