The ICD-10 deadline is here and Apex EDI realizes that you may need additional resources to help make the transition smooth. We have compiled three fact sheets identifying commonly used ICD-9-CM codes and matching them with their possible ICD-10-CM equivalents, one sheet for General Medicine codes, one for Ophthalmology codes, and one for Chiropractic codes.
Please note this tool is not designed to provide perfect matches between the two coding systems. In fact, except for a minority of cases, perfect matches between the ICD-9-CM and ICD-10-CM coding systems do not exist. Given the significant increase in detail and specificity in the ICD-10-CM coding system, in most cases there is no direct match between ICD-9 and ICD-10 codes. A clinical analysis is required to determine which code or codes should be used. It is important to remember that even when there is only one ICD-10 code, it is not necessarily completely equivalent to the source ICD-9 code. This tool is not designed to replace proper training and documentation.
Proper coding begins with the doctor and documentation. While Medicare Part B is not going to deny claims based solely on the specificity of the ICD-10 diagnosis code as long as the codes are from the right family, they may pay less than what they have paid in the past based on the specificity of the diagnosis code. These tools are meant to shorten the amount of time spent looking up codes for best specificity. Most of the conversions identify the family where the appropriate crosswalk can be found. In the rare occasions where there is a direct crosswalk a clinical analysis is still required to determine if the crosswalk is appropriate for the billing situation.
