The compliance date for the ICD9-ICD10 transition is October 1, 2015. The hospitals have started the ICD9-ICD10 transition. However, not all data providers will transition the data at the same time. In order to facilitate some coherence to the data during this transition period, user interface and data processing functionalities have been developed in ESSENCE to allow usage of both classification systems simultaneously. This capability will allow users to perform ICD10- based queries across all the hospitals in their system, irrespective of the exact number of hospitals that have completed the ICD10 transition.
Objective
To help users seamlessly query and analyze data in disease surveillance systems using both ICD9 and ICD10 codes during the transition period. Additionally, the mappings between ICD9 and ICD10 codes must be flexible enough to support locally required changes based upon a user’s needs.
