Some practices that use Athelas for billing can't select an appointment type when adding a walk-in patient from the Appointments page. The appointment type list shows "No Options". We've identified the cause, a recent update, and are rolling out a fix. Affected practices that have reported it should already be able to add walk-ins again after refreshing the page. Existing appointments, claims and patient data are not affected. We'll post another update once the fix is fully deployed.
