ICD-10-CM Master Mapping Reference Table

ICD-10-CM Master Mapping Reference Table

The ICD-10-CM Master Mapping Reference Table (MMRT) is a tool and resource to assist public health professionals in code-mapping conversion between ICD-9-CM to ICD-10-CM.

Background

The upcoming ICD-9/ICD-10 transition will have a significant impact on public health surveillance systems and activities that involve coded clinical data. It is imperative that public health agencies begin to prepare their systems, modify current business processes, and train their workforce to ensure a seamless transition to ICD-10-CM coded data. To address this urgent need, CDC worked with clinicians and public health professionals to develop ICD-9-CM to ICD-10-CM translations based on conceptual mapping for 140 syndromes arranged into 16 broader syndrome groupings. ISDS coordinated the community input on these codesets and concepts, to ensure that they reflect how public health agencies use diagnostic codes for syndromic surveillance activities. Three reviews for each syndrome chapter were compiled, and a panel of syndromic surveillance experts subsequently assessed that the reviews for inclusion. The resulting reference tables, which include 90 syndromes grouped into 13 chapters, serve as a resource for public health agencies looking to ensure a smooth transition between ICD-9-CM and ICD-10-CM code-mapping.

Best utilizing the MMRT to assist in the transition from ICD-9-CM to ICD-10-CM codes will look different in every jursidiction. The following is an example of New Hampshire's ICD-10 transition process:

How to Prepare for the ICD-10-CM Transition with the MMRT - New Hampshire Example

1.  Identify how ICD diagnosis codes are used in your syndromic surveillance system.

2.  If used for surveillance, alerting, reporting, analysis, download ICD codes from CMS to add to your database. Additional ICD-10-CM fields will be added to the database based on needs; data is not formattted and special processing is needed to format the data.

3. Once codes have been downloaded and ICD-10 field/s have been added to the database, a reportable disease alert table was created using ICD-9-CM to ICD-10-CM conversion tools, then ICD-10-CM alerting was added to the system

4.  Decide how to transmit ICD codes (for instance, will hospital providers send both ICD-9-CM and ICD-10-CM codes or only send one format); and how to differentiate in HL7 messaging (i.e. use of DG1 field 3.3 values of I10 for ICD-10-CM codes or I9CDX).

5.  Decide how to handle comparisons with prior years (convert new data to ICD-9-CM format to  match prior years or convert prior years to ICD-10-CM format); and how to handle processing for 2015 which is a mixed ICD-9-CM/ICD-10-CM coding year.

6.  Review and modify reporting forms, caveats, other documents.
