ICD-9-CM↔ICD-10-CM Crosswalk


Comprehensive ICD-9-CM to ICD-10-CM crosswalk — developed by coding experts!

Simplify translating ICD-9-CM to ICD-10-CM (and vice versa) with the crosswalk that covers all the bases. Our crosswalk includes results based on the CMS GEMs crosswalk and on our own extended logics. The 2018 GEMs provide the CMS ICD-9 to ICD-10 crosswalk. Our own extended logics go one step further, providing more specific ICD-10-CM code options for each ICD-9-CM code. Why? Diagnosis code specificity is key to supporting medical necessity for claims and accurate payment.


Providers, payers, billing companies, EHR vendors, and practice management software vendors can count on our customized ICD-10 crosswalk to navigate ICD-10-CM. Choose the ICD-9 to ICD-10 crosswalk download for quick access and easy integration with your specific system.

The information in our data files is a combination of official data and the TCI team’s expert analysis. For instance, we have official data such as AMA’s code descriptors for the CPT® code set and Medicare’s relative value units from the physician fee schedule. Our medical coding and IT teams then take that information and create files that make the data easily accessible. We are also able to combine and add to the official data to make it more useful. An example is the CPT® ↔ ICD-10-CM Crosswalk, featuring official codes and short descriptors as well as code combinations carefully reviewed by our experienced medical coding team.

To create our data files, our internal IT and medical coding teams take the information provided from the data source and compile that data based on your specific requirements. The data source may be CMS, an official code set, TCI-created databases (such as crosswalks), or a combination of the above, depending on the specific data file requested. To ensure quality, an auditor from the coding team reviews the data file. We then go the extra mile with an additional QC check of the data file by a certified professional expert on TCI SuperCoder’s content team.
The answer is specific to your agreement with TCI SuperCoder and the particular data files you select. For instance, if you choose a data file with data that CMS updates quarterly (such as MPFS RVUs or NCCI), you have the option to include quarterly updates in your agreement. Be sure to discuss update options with your dedicated sales representative.
