This extension enables payers to provide an image of the QR code found on a member’s physicial insurance card. This image may be displayed by consuming applications when rendering the coverage information for use by the health plan member. Often there are data elements relevant to the health plan coverage encoded in the QR code. The extension also allows for the health plan to provide a Label for the image which can be displayed in the consuming application as well as a Description of the content in the image file. Detailed descriptions are encouraged to assist with accessibility.
