Clearinghouse/Direct Connections for Electronic Data Exchange

Kaiser Foundation Health Plan of Washington utilizes business-to-business electronic data interchange (EDI) to facilitate our claims processing, patient billing, and care management systems.

EDI exchanges include both ASC X12 formatted transactions and some non-X12 data exchanges. The X12 formatted transactions may be exchanged using a direct connection with Kaiser Permanente or an affiliated clearinghouse. (PDF)

A direct connection is available if you can answer Yes to all three of these questions:

  • Are you submitting more than 250 electronic claims per month?
  • Do you have the ability to process HIPAA-compliant X12 electronic transactions?
  • Can you submit secure file transfers (secure channel or encryption such as PGP or Gnu PG)?
