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. A large number 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 beginning at 7:10 PM ET and anticipates that service will be restored by 8:10 PM ET.
Please contact the Help Desk if you need additional information.
