CMS Pub. 100-04, ch. 24, § 50.3
Combined Common Edits/Enhancements Module (CCEM) -
General Description Across All Versions
(Rev. 13105; Issued- 04-10-25; Effective: 05-12-25; Implementation: 05-12-25)
The CCEM establishes consistent editing, acknowledgments, and error handling of the
electronic data interchange (EDI) transactions across Medicare Administrative Contractor
(MAC) jurisdictions. The CCEM is implemented by each A/B MAC in their local data
center (LDC). The Part A and Part B CCEMs were developed by their corresponding
Medicare Shared System Maintainers (SSMs). The Durable Medical Equipment (DME)
MACs editing, acknowledgment, and error handling of EDI transactions is processed by
the Common Electronic Data Interchange (CEDI) contractor. Each A/B MAC has
integrated the CCEM into its Front-End Systems for both inbound and outbound EDI
transaction processing. The CCEM, in conjunction with the A/B MAC Commercial Off-the-Shelf (COTS) translator and any additional Front End Solution, is responsible for
editing current ASC X12 standard transactions established under HIPAA via Technical
Report Type 3 (TR3s).
The CCEM provides submitters with quicker acknowledgments for the claim
transaction(s) ASC X12 version(s) 005010 and beyond inclusive of any adopted errata
under HIPAA. This allows submitters to correct any errors and resubmit their
transactions without having to wait for a batch cycle.
The CCEM includes the following capabilities:
• Code set editing
• Medicare-specific editing
• Duplicate submission checking
• Claim Control Number assignment of Internal Control Number (ICN) or
Document Control Number (DCN)
• Creation of the ASC X12 277CA claim acknowledgment (flat file)
• Creation of a CCEM-edited transaction flat file
• Receipt/Control/Balancing between the local data centers (LDCs) and EDCs for
claims, claim status request and responses, and remittance advice
• Reporting Capabilities based on the Control Record database
