ICD-10 to 9 Mapping Client User Guide 1

Navicure ICD-10 to 9 Mapping Guide Background The transition from ICD-9 to ICD-10 greatly expands the number of available diagnosis codes from approximately 13,000 to 68,000 codes, thus potentially having a drastic impact on providers and health plans encountering billing and payment issues. Navicure is prepared to meet the current ICD-10 compliance date of October 1, 2015, and is committed to making the move to ICD-10 as smooth as possible for our clients. We have established the ICD-10 to 9 Mapping process to map certain professional claims containing ICD-10 codes to the corresponding ICD-9 codes. This automated solution is for clients that have Opted-in and utilizes the publicly available General Equivalence Mappings distributed by CMS ( GEMS ) to map backward from an ICD-10 code where there is a direct correlation to an ICD-9 code. When a Client that has Opted-in submits an ICD-10 coded claim(s) to a payer that requires an ICD-9 code, the code will be mapped if there is a one-to-one relationship between the ICD-10 code and the ICD-9 code. Navicure will store both ICD-10 and ICD-9 codes on the mapped claim(s) and can be viewed within Navicure s online HCFA. The mapping process will not occur if there are multiple matches, or if there are no matches, to the ICD-10 code. When an ICD-10 code cannot be directly correlated with an ICD-9 code, the claim will reject within the Navicure Application and Client will be directed to provide the appropriate ICD-9 code. It is important to note that Institutional and Paper Claims are not included in ICD-10 to 9 Mapping processes. Mapping Scenarios: Following are scenarios for ICD-10 to 9 mapping that will be encountered when ICD-10 claims are submitted and payer(s) are only able to receive ICD-9 codes: 1 to 1 Match o Able to map and proceeds through regular Navicure processes 1 to Many o Unable to map and will display in Rejections 1 to No Match o Unable to map and will display in Rejections Examples of ICD-10 to 9 Mapping: Mapping ICD-10 ICD-9 Ability to Map 1 to 1 Match E21.3 252 1 to 1 Match D35.00, D35.01, D35.02 227 1 to Many I10 401, 401.1, 401.9 X 1 to No Match R40.213 No Dx X 3
