ICD-10-CM Coding Resources
THINGS HAVE CHANGED. It's never been more important to code correctly.
In the United States, we’ve been using the ICD-9-CM code set since the late 1970s. We transitioned to the new system, ICD-10-CM on October 15, 2015.
The ICD-10-CM diagnosis classification system was developed by the Centers for Disease Control and Prevention for use in all U.S. health care treatment settings. Diagnosis coding under this system uses an alpha-numeric numbering system to report a condition and vastly expands the number of diagnosis codes that may be reported.
The following resources will help your practice answer common questions and troubleshoot issues after moving to ICD-10-CM.
- Center for Disease Control PDFs are available for the ICD-10-CM tabular list, alphabetical list, as well as the tables of neoplasms, drugs, and external causes. Most files are provided in compressed zip format for ease in downloading.
- ICD-10 Conversion Tool This site breaks down ICD-10-CM by chapter and includes a searchable ICD-10-CM alphabetical list, table of drugs, neoplasms and external causes. It also converts, when possible, ICD-9-CM codes to ICD-10-CM codes.
