The guillotine is a machine used to execute people by decapitation (chopping off their heads). A guillotine is made of a heavy blade attached to a rack, which moves up and down on a vertical frame. When the rack is let go, it will fall down and the blade will cut the convict's head off.
A national producer number, or NPN, is a tool to protect individual insurance agents and agencies from identity theft and fraudulent representations made to the National Insurance Producer Registry, or NIPR.
The NPI replaced the UPIN (Unique Provider Identification Number) which was used in the past. Without the NPI, health care providers (including pharmacies) cannot be paid by their insurance companies. Insurance companies require the prescribers NPI and/or DEA Number transmitted to them each time a prescription is submitted to them for reimbursement.
