About ICD-10-CM To ICD-9-CM Conversion Tool

The US. Center for Medicare and Medicaid Services released General Equivalency Mappings (GEMS). We utilized the science of networks to quantify the proportion of ambiguities arising from abstruse CMS translations. This analysis was performed with codes as nodes and translations as directional arrows and synthesized five translation pattern categories: one-to-one, class-to-subclass, subclass-to-class, convoluted and no translation. Four different views are possible. One is a network view showing all of the translations in a graphical format with the appropriate labels for the transitions. The second is an online table that will also input the value submitted with the codes for additional analysis, in a tablular form all of the translations associated with the ICD-10-CM codes of interest are included. The third method is the same as table as in method two, but is stored as a tab delaminated file. The fourth method only lists the ICD-10-CM codes of interst, submitted values, and Translation Category as a tab delimitate file.
