Of course, new HIPAA laws require that businesses use caution when sending any correspondence to a patient that might expose private health information. Please consult with a professional that is qualified to advise you on proper HIPAA protocols when sending postcards. With that in mind, you can add custom postcard templates for any HIPAA compliant reason to send postcards. HearForm allows you to print to part and four-port postcards to a large group of patients easily. Avery and other companies offer ready to print postcards.
