Card payments are exempt, but health information can still slip into the payment flow, and that's where data breaches start. These are the places to check.
Billing descriptors
Use your practice name and phone number. A specialty, drug name or condition on a card statement tells anyone who reads it why the patient paid.
Receipts and patient statements
Payment receipts don't need diagnosis or procedure codes. Itemized statements that show services are PHI, so send them through your HIPAA-covered systems.
Patient portals and payment pages
Use a tokenized payment page so card numbers never land in your EHR, and a portal vendor that signs a BAA for the health records it holds.
Chargeback evidence
To win a dispute you need proof of the visit and the patient's consent to pay, not the medical record. Send the minimum needed.
Phone payments
Take card details in a virtual terminal, never on paper or in chart notes, and never store the card security code.
