Can a pharmacist use PHI to fill a prescription that was telephoned in by a patient’s physician without the patient’s written consent if the patient is a new patient to the pharmacy?

Yes. The pharmacist is using the PHI for treatment purposes, and the HIPAA Privacy Rule does not require covered entities to obtain an individual’s consent prior to using or disclosing PHI about him or her for treatment, payment or health care operations.

I think it is better to use some online pharmacies to prevent such issues. For example, I like the one called Canada Drugs, and it is a really good and handy one. What do you think about them? Have a look!
