UCD System to Go Down for Maintenance

Friday, Aug. 22, 2008 through Monday, Sept. 1, 2008

As part of the previously announced transition to a new vendor, the CAQH Universal
Credentialing Datasource (UCD) service will be down for maintenance beginning
7:00 p.m., Friday, Aug. 22, 2008 through Monday, Sept. 1, 2008. CAQH expects the
service to be back up and available for use at 7:00 a.m. ET, Tuesday, Sept. 2, 2008.

According to CAQH, the following will occur during this maintenance period:

• The UCD Support Desk will not be available. When service resumes on
  Tuesday, Sept. 2, 2008, the UCD Support Desk will have a new email address:
  caqh.updhelp@acsgs.com. The toll-free phone number – (888) 599-1771 – will
  not change.
• The Universal Credentialing Datasource will be re-named the Universal Provider
  Datasource.
• The Online Application System (OAS) and Practice Administrator Module
  (PMM) will be moved to the new URLs below. Although providers will be
  redirected automatically to the new URLs for several months, CAQH
  recommends that providers change their browser bookmark(s) as soon as
  possible.

All supporting documents faxed to UCD between 9:00 p.m. ET, Wednesday, Aug. 20,
2008 and Monday, Sept. 2, 2008 will not be processed until after service resumes.
Additional provider information is available at www.caqh.org/ucdstatus/. Providers may
also contact CAQH at info@caqh.org for any other questions.
