Use our ICD-9 conversion utility to convert legacy ICD-9 codes to ICD-10 codes using the General Equivalence Mappings (GEM). The purpose of the GEM is to create a useful and practical code to code translation from ICD-9 to ICD-10, and to offer alternatives wherever possible. Mappings from specific concepts to more general concepts are possible, however, it is not possible to use mappings to add specificity when the original information is general.
Convert any valid ICD-9 Diagnosis or Procedure code to ICD-10 (CM or PCS). The conversion is based on current code mappings in the General Equivalence Mappings from the CMS.
Care should be taken when converting legacy ICD-9 codes to ICD-10, as most DO NOT have equivalent mappings. In some cases, the correlation between codes is fairly close and translating between them is straightforward. In other cases, translating between them can offer only a series of possibilities rather than an exact translation of one code to the other.
