Providers can charge a reasonable amount that relates to their cost of providing the copy, however, no charge is allowable when providing data electronically from a certified EHR using the "view, download, and transfer" feature which is required for certification. When delivered to the individual in electronic form, the individual may authorize delivery using either encrypted or un-encrypted email, delivery using media (USB drive, CD, etc., which may involve a charge), direct messaging (a secure email technology in common use in the healthcare industry), or possibly other methods. When using un-encrypted email, the individual must understand and accept the risks to privacy using this technology (the information may be intercepted and examined by others). Regardless of delivery technology, a provider must continue to fully secure the PHI while in their system and can deny the delivery method if it poses additional risk to PHI while in their system.
