10.2 – MSP Contractor Electronic Correspondence Referral System (ECRS)
(Rev. 13856; Issued: 07-10-26; Effective:08-10-26; Implementation: 08-10-26)
The MSP Contractor (formerly known as the Coordination of Benefits Contractor (COBC)) assumes
responsibility for virtually all activities related to establishing MSP periods of coverage at CWF that
result from initial MSP development activities. Since the A/B MACs and DME MACs receive MSP
information, the MACs must utilize the ECRS Web application to send MSP information to the MSP
Contractor. The ECRS Web application allows A/B MAC and DME MAC MSP representatives and
Regional Office MSP staff to complete the online forms and electronically transmit information to
the MSP Contractor.
The ECRS is operational 24 hours a day, 7 days a week, except for maintenance. A/B MACs and
DME MACs shall report connection problems or systems failures directly to the MSP Contractor
EDI Hotline at 646-458-6740. If A/B MACs and DME MACs are unable to receive technical
assistance from the MSP Contractor EDI Hotline, or the issue has not been resolved, please E-mail
questions or issues should be forwarded to the MSP Contractor via Internet address at
ECRSHELP@ehmedicare.com.
