Make the call count.

Find technical support for portal access and electronic transactions. Clearinghouse acceptance is separate from payer claim acceptance.

Have ready in your secure workspace

  • Portal name or transaction type
  • Error code and timestamp without patient data
  • Account administrator and transaction trace reference

Questions to resolve

  • Is this a portal permission, clearinghouse or payer issue?
  • What trace identifier is needed through the secure support channel?
  • How will the office confirm the issue is resolved?

This is a general administrative checklist, not payer policy or advice about a particular patient. Confirm the current plan instructions.
