Claims: Authorization, Referral, or EAP Numbers
Whether you have a number for a prior authorization, single case agreement, referral, EAP, or something else, you may add this to a claim prior to submitting it. When creating a claim, navigate to the Details > Other tab.
In the Additional Claims Information panel, click Edit. Next, check the Include additional claims field box. Scroll down to the Prior Authorization Number field, enter your authorization number, and click Save.

Your authorization code will then be included when you submit the claim.
Note: When you add a prior authorization number to a claim, each consecutive claim will include that number until you remove it. You may also add a Prior Authorization Number in a client's Billing > Settings page and any claims generated will automatically include that Prior Authorization Number.
