Medi-Cal Subscription Service (MCSS) is Live

Published May 31, 2022


The Department of Health Care Services (DHCS) is pleased to announce that the Medi-Cal Subscription Service (MCSS) is up and running.

For providers and Medi-Cal stakeholders unfamiliar with the service, MCSS is a free service that sends subscribers subject-specific emails based on the provider communities they have subscribed to. This keeps subscribers up-to-date when urgent announcements and other updates post to the Medi-Cal Providers website.

DHCS took the service down in October 2021 to address some necessary changes. The returning MCSS retains the functionality and look-and-feel of the service subscribers are familiar with. However, DHCS wishes to highlight one change and one action required of subscribers to ensure they receive MCSS emails once the service is turned back on:

  • Sent From Email Changed: Emails received via MCSS will be sent from the following email address:

  • Subscriber Action: The first few messages from MCSS may appear in spam or promotional inboxes. To avoid this, and to ensure they receive the latest messages from Medi-Cal fee-for-service, subscribers are instructed to add to their list of approved senders. Note that the exact instructions on how to add an email to the list of approved senders, will change depending on the email client in use. Medi-Cal has identified some frequently used email domains and resources on how to manage an approved senders list:

  • Without taking action to add to the list of approved senders, it is possible that MCSS messages will either be blocked from the subscriber’s account or be filtered into Spam/Promotional folders.

Returning MCSS Subscribers

Subscribers should keep an eye out for a “Welcome Back” email to verify receipt of MCSS emails.

DHCS recommends existing subscribers add to their approved sender list to resume receiving MCSS emails. This is the only action needed. You do not need to re-subscribe for MCSS. To verify if subscribers have appropriately added to an approved senders list check that the “Welcome Back” email is in the inbox as opposed to spam, promotional or junk folders.

DHCS will not send MCSS emails for publications published between October 2021 and May 2022. Instead, the “Welcome Back” email will highlight major changes and point to additional resources on any missed updates. Medi-Cal apologizes for any inconvenience this may cause.

Existing subscribers can update their subscription preferences through a link in the footer of MCSS emails they receive. Only the most recent MCSS email will properly update subscription preferences.

New MCSS Subscribers

New subscribers can sign up now using the current MCSS Subscription Form. Upon subscribing, subscribers will receive a “Welcome to MCSS” email. Refer to the above resources under the subscriber action bullet for resources on managing an approved senders list. should be added as an approved sender.
