Patients trust you with their prescriptions. The payment side should never give that away.
Keep drug names off statements
Use your pharmacy's name and a phone number as the billing descriptor. A medication name on a card statement is a privacy problem and a reason for disputes.
Keep health details out of payment data
Card payments are exempt from HIPAA, but your order data isn't private by default. Keep diagnoses and drug names out of receipts, order notes and chargeback evidence.
Make refills easy to manage
Get consent to the refill schedule, remind patients before each charge and let them cancel online. Most refill disputes come from patients who forgot they signed up.
