Medicare HETS 270/271 Submitters:

The Medicare 270/271 Eligibility system is currently returning responses with higher than normal average response times. Some requests are receiving a proper 271 response from Medicare, but the average response time for these requests is higher than normal. The majority of requests are receiving AAA03=42 'System Unavailable' time out responses from the system.

This issue has been escalated to CMS IT for review and resolution. CMS will perform emergency maintenance on the HETS 270/271 Eligibility system and anticipates that service will be restored by 3:00 PM ET.

Please contact the Help Desk if you need additional information.
