Understanding The Health Language SNOMED CT To ICD-10 Maps

As specified by Meaningful Use Stage 2, the 2014 edition of EHR certification will require problem list entries to have SNOMED CT encoding. Since October 1, 2014, diagnoses must be encoded in ICD-10-CM for billing. After that time personnel and systems will need to convert problem list entries (in SNOMED CT) to billing diagnoses (in ICD-10-CM). Sophisticated SNOMED CT / ICD-10-CM mapping is required to allow this task to be done efficiently and accurately.

THE NLM MAPS

To meet this need, the NLM (National Library of Medicine) has released maps from over 35,000 SNOMED CT concepts to ICD-10-CM concepts (for details, see www.nlm.nih.gov/ research/umls/mapping_projects/ snomedct_to_icd10cm.html).

These are rules-based maps that allow algorithmic derivation of an ICD-10-CM target from a given SNOMED CT source concept.
