The account owner can change the credit card used for monthly CabMD billing by going to the Dashboard and clicking the 'Billing Settings' tab under 'Account'. Once on the info screen, click the 'Update' button under the care provider entry in the table. This will open a secure link to allow you to update your credit card easily.
Once the new window appears, fill in the mandatory information with the *s next to them. When you are finished filling out all of the information, click "Finish" to save the update.
When you have added the new credit card to the CabMD account, you have to associate that credit card with your account. In the second step, use the drop down menu to highlight and select the new credit card. After you select the card, the CabMD billing settings will be updated.
