AWS will be deprecating the aws-portal:ViewBilling and aws-portal:ViewUsage permissions which are currently used in CloudHealth IAM policies.

https://aws.amazon.com/blogs/aws-cloud-financial-management/changes-to-aws-billing-cost-management-and-account-consoles-permissions/

CloudHealth is aware of this change and has determined that these permissions are no longer used for CloudHealth.  These permissions will be removed from the default policies, and should not affect AWS integration when they are deprecated.
