CONNECTION OVERVIEW

Trading Partners will access the CMS Data Center, via the AT&T communication Extranet, over the Medicare Data Communication Network (MDCN) to send their eligibility request. This Extranet is a secure, closed, private network currently used to transmit data between Medicare Fee-for-Service (FFS) contractors and CMS.

For a 270 real-time inquiry, the software at the CMS data center will translate the incoming 270, perform validations, request Beneficiary eligibility information from the CMS eligibility database, and create either a 271, 997, TA1 or a proprietary response.

CMS will continue to hold the Clearinghouses responsible for the privacy and security of eligibility transactions sent directly to them from Providers, and require them to be able to associate each inquiry with a Provider. Provider authentication must be established outside of the transaction. Trading Partners must not send User IDs and passwords within the 270 eligibility transaction.

HOW TO OBTAIN A CONNECTION TO THIS SERVICE

To sign up as an extranet eligibility submitter, your organization must complete the following forms to obtain a connection to the Medicare Data Communication Network (MDCN) via an AT&T Global Network Service (AGNS) connection: Trading Partner Agreement for Submission of 270s to Medicare on a Real-Time Basis, Eligibility Rules of Behavior, and MDCN Connectivity Form. You can obtain an AGNS connection from one of the approved AT&T resellers: AAMVA, IVANS or McKesson. Contact information for each company is available on the "Sign Up Now" page. Please contact the AT&T resellers for pricing and additional information.

Once you have reached the MDCN via an AGNS connection, you can then access the Medicare HETS 270/271 Eligibility system to inquire for eligibility.

WHAT TO DO IF YOUR CONNECTION CLOSES

The Extranet eligibility system will automatically terminate a session (without notice) if the socket has been idle for more than 5 seconds. If this occurs, open a new socket and resume sending transactions
