Certification Number (CCN) State Codes –State Operations Manual (SOM) Section 2779A Revisions
• SOM Section 2779A: The Centers for Medicare & Medicaid Services (CMS) has made revisions to this section in the SOM which
provides guidance regarding the numbering system for CCNs for Medicare-participating providers and suppliers. The revision,
specifically in Section 2779A1 for Medicare providers reflects the addition of new State Codes.
• Additional State Codes: Due to a lack of available CCNs for some providers wishing to enroll or modify their current certification
in Medicare, additional State codes are being added to the Automated Survey Processing Environment (ASPEN), the Accrediting
Organization System for Storing User Recorded Experiences (ASSURE), as well as Medicare payment processing systems, effective
April 4, 2016.
