as a medic i can say its because doing transfers from one hospital to another hospital / pts name are given.
you said " communicate with hospitals for patient reports"that is not dispatch calls .
How does HIPAA apply to dispatch information and information discussed over the radio?
Generally, these communications are treatment-related disclosures. As long as they're related to treatment, those are generally permissible disclosures under HIPAA. Communications between field units and transporting entities communicating by radio to the hospital-these are all necessary for treatment so those are permitted disclosures. A lot of responders sort of assume they can no longer talk on the radio, which is not at all the case under HIPAA, but they should use discretion. It doesn't require that you build new towers and implement new technology, or that your transmissions be encrypted. There are no such requirements. If it's not necessary to give a name over the radio, just don't give a name. You can still transmit information to field responders and between field responders and other necessary entities when it's necessary for treatment. There really are no restrictions on that.
with that said most prob do chose to encrypt to cya
